| ELB-1210 | New Feature | Drop Qt4 and Image Recipes Based on Qt4 | Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30, Apalis iMX8 | Buildsystem | Low | No |
Description: Qt 4 was first released in 2005 and has been unsupported since 2015.
For our 3.0 (thud based) release we remove meta-qt4 from the installed layers and
remove related image recipes. Workaround: Forward port applications to use Qt 5. |
| This release supports Apalis TK1, Apalis iMX6, Apalis iMX8, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7 and Colibri iMX8X in addition to Apalis iMX8QM V1.0B. See more at https://www.toradex.com/news/3-0b2-embedded-linux-bsps-for-apalis-colibri-system-on-modules |
| ELB-1078 | New Feature | Supported Modules: Colibri iMX6/6ULL/7/8X Apalis IMX8 / TK1 | Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: On the Colibri VF50, VF61, T20, T30 and Apalis T30 we will continue maintaining our long-term supported (LTS) BSP 2.8. We are providing updates when there are any HW changes on those platforms, and we will regularly provide critical bug fixes. Workaround: BSP 2.8 Long Term Support |
| 2.8 maintenance release. Learn more on https://www.toradex.com/news/2-8-7-embedded-linux-yocto-project-bsps-for-apalis-colibri-system-on-modules |
| ELB-1404 | New Feature | Toradex Linux BSP 2.8 Updating OpenSSL 1.1.1d | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Update OpenSSL to version 1.1.1d |
| 2.8 contains all changes up to 2.8b6. |
| ELB-980 | New Feature | 2.8 Stable Release | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: The 2.8 stable release contains all changes up to 2.8b6. |
| ELB-1139 | New Feature | Move from CRDA to in-kernel for Wi-Fi Regulatory Domain Database | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Wi-Fi | Low | No |
Description: We switched from CRDA to direct loading of the Wi-Fi regulatory domain database in-kernel. |
| ELB-1047 | Fixed | iptables Not Supported by Default Linux Kernel Configuration | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Ethernet | Low | No |
Description: iptables -L is not supported by our default Linux kernel configuration. Workaround: A custom Linux Kernel compilation with correct configuration can solve the issue. The correct Linux kernel configuration is e.g. described here:
https://wiki.gentoo.org/wiki/Iptables |
| ELB-1082 | Fixed | Capacitive Touch Not Working Reliably | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Capacitive Touch | Low | No |
Description: The touchscreen with 7" Capacitive Touch Display may not work well when used either on an Evaluation Board with the Capacitive Touch Adapter or on Aster or Ixora. |
| ELB-1051 | New Feature | Update Wi-Fi Backports to 4.18 | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Wi-Fi | Low | No |
Description: Update Wi-Fi Backports to 4.18 |
| ELB-1014 | New Feature | Add support for new [01491101] CSI Camera Module 5MP OV5640 V1.1B | Apalis iMX6, Apalis TK1, Apalis T30 | CSI | Low | No |
Description: The only difference from [01491101] CSI Camera Module 5MP OV5640 V1.1B to the old version V1.1A is about pin 12 (Master clock). This signal isn't used on V1.1B anymore as an oscillator is assembled on the V1.1B version. This improves EMI behavior and also works with SoMs which don't provide a master clock. |
| ELB-965 | Fixed | Legacy Update Procedure May Fail on Debian Stretch or Arch Linux | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Generating a legacy update media using Debian Stretch and subsequently updating an Apalis TK1 failed during mounting the root file system. Workaround: We recommend using the Toradex easy installer on platforms where it is supported.
For the legacy update procedure, the easiest is to use one of the supported distributions:
https://developer.toradex.com/knowledge-base/board-support-package/openembedded-(core)#Prerequisites
Other distributions may have the option metadata_csum enabled per default for mkfs.ext4 (Debian Stretch, Arch, ...). This option is not supported on Linux kernels below 3.18 and generates a kernel panic during boot after the legacy update. As a workaround, one can disable this option in /etc/mke2fs.conf before executing the update.sh script. The ext4 man page also has a list of options with their corresponding supported kernels, which may be helpful to refer to in case of legacy update attempts on more exotic systems. |
| ELB-951 | Fixed | Do Not Enforce Building 32-Bit Host Binaries | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Enforcing to build 32-bit binaries for native and portions thereof using -m32 in EXTRA_OEMAKE_class-native may lead to the following error when building e.g. u-boot-toradex:
cbootimage: Accessing a corrupted shared library Workaround: The -m32 as specified in EXTRA_OEMAKE_class-native in recipes-bsp/cbootimage/cbootimage.bb of meta-toradex-tegra may be overridden to your liking. The same applies to the following as well:
meta-toradex-demos: recipes-devtools/mtd/mtd-utils_%.bbappend
meta-toradex-nxp: recipes-devtools/imx-loader/imx-loader_git.bb
meta-toradex-tegra: recipes-bsp/tegrarcm/tegrarcm.bb
meta-toradex-tegra: recipes-support/libcryptopp/libcryptopp_5.6.4.bb |
| ELB-932 | New Feature | Image Features do not Work with Toradex Console Image | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Image features (e.g. tools-debug or others documented at https://www.yoctoproject.org/docs/2.2/ref-manual/ref-manual.html#ref-features-image) do currently not work with the console-tdx-image. The reason is that the image is inheriting from image as opposed to core-image. Workaround: You may use core-image instead but it might have additional effects. |
| ELB-915 | New Feature | Disable Display Backlight before Starting Linux | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Bootloader, RGB | Low | No |
Description: U-Boot typically tears down the display controller before handing control over to Linux. On LCD displays disabling pixel clock leads to a fading out effect with vertical/horizontal lines. Make sure to disable back light before booting Linux. |
| ELB-493 | Fixed | Support MXM/SODIMM Pin Numbers to Get/Set GPIOs | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | GPIO | Low | No |
Description: Allow using MXM or SODIMM pin numbers to get or set GPIOs. This also allows for easier code porting from one to another Toradex module. |
| ELB-258 | New Feature | Deploy Device Tree(s) | Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem, Device Tree | Low | No |
Description: In OE we build the device trees listed in conf/machine/xxx.conf (build-time variable KERNEL_DEVICETREE) and put them into the image.
In the update.sh script we currently also have a variable KERNEL_DEVICETREE with a list of what to put on the update media.
We could patch update.sh in OE during image creation time, so that update.sh contains the list from conf/machine/xxx.conf rather than having to maintain that list in both places. |
| ELB-981 | Fixed | Yocto Project Layer Readmes May Not be Up-to-date | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Our Yocto Project layer readmes may not be up-to-date. Workaround: Make sure to use valid combinations e.g. as available as tagged repo meta data:
http://git.toradex.com/cgit/toradex-bsp-platform.git |
| ELB-960 | Fixed | Building on Ubuntu 18.04 Fails | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Building 2.8b2 and earlier fails on Ubuntu 18.04 LTS. Workaround: It works on Ubuntu 16.04 LTS. |
| ELB-926 | Fixed | Toradex Configuration Block Off by One Issue | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Bootloader, ConfigBlock | Low | No |
Description: Currently the Toradex configuration block parser suffers an off by one issue potentially leading to spurious printout during boot e.g.
Model: Toradex V1.2A,
instead of
Model: Toradex UNKNOWN MODULE V1.2A. Workaround: Fix available on 2016.11-toradex-next branch of git.toradex.com/u-boot-toradex.git. |
| ELB-925 | Fixed | Can Not Install Individual Backport Kernel Module | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Installing a single backport kernel module to an image at build time fails (e.g. by using IMAGE_INSTALL_append in local.conf). Workaround: Install all backport kernel modules by using the "backports" package. |
| ELB-916 | Fixed | Add Atmel mxt touch controller driver support for reset gpio | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Capacitive Touch | Low | No |
Description: To get atmel mxt based touchscreens with GPIO connected reset line to work GPIO needs to be configured as an output with appropriate level separately. |
| ELB-906 | Fixed | Make Latest OE-Core, Morty Compatible With meta-toradex-bsp-common | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: OE-Core layer did backport more package splits in the linux-firmware recipe. Due to this the HEAD of the morty branch clashes now with a similar split we did in meta-toradex-bsp-common resulting in a fatal QA error. (Compare with commit 0eaef98)
ERROR: linux-firmware-1_0.0+gitAUTOINC+bf04291309-r0 do_package: QA Issue: linux-firmware-sd8887 is listed in PACKAGES multiple times, this leads to packaging errors. [packages-list] Workaround: Delete the lines

| ELB-904 | New Feature | Add Configuration File(s) And mxt-app to Allow Loading It For PCAP Touch Screens | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Capacitive Touch | Low | No |
Description: In order to allow our customers easy re-flashing of the touch controller configuration, we need to add the mxt-app as well as the proper configuration files to our images. Workaround: https://www.toradex.com/community/questions/25020/view.html |
| ELB-903 | New Feature | Adding perf to all eMMC-based Images | Colibri iMX7, Apalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Adding perf to all eMMC-based Images which are less space-constrained than raw NAND ones. Workaround: You may build a custom image including perf according to your requirements. |
| In this release we switched to the generic compressed Kernel image type (zImage) instead of the legacy U-Boot specific uImage format. This could lead to non booting modules if a previously saved U-Boot environment is still set to uImage. Please see the following issue for more details: http://developer.toradex.com/software/linux/linux-software/release-details?view=all&issue=17925 |
| ELB-909 | Fixed | Fix scrot Recipe Source/Mirror | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: The scrot recipe source is 404. |
| ELB-899 | Fixed | Regression: Automounting Fails With systemd udev Rules | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem, SATA, SDIO/SD/MMC, USB | Low | No |
Description: The update to rocko (BSP 2.8b1) made automount fail for systems which do not trigger mounting through dbus/udisk2, i.e. which rely on udev rules. |
| ELB-897 | Fixed | Bitbaking stress Reports Checksum Mismatch | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: When building 2.8b1 building stress fails with "ERROR: stress-1.0.4-r0 do_fetch: Fetcher failure for URL: 'http://people.seas.harvard.edu/~apw/stress/stress-1.0.4.tar.gz'. Checksum mismatch!". Workaround: Use 2.8b2 or remove the stress recipe under "meta-toradex-demos/recipes-support/stress/stress_1.0.4.bb" (this will use a fixed version of stress in openembedded-core/meta/recipes-extended/). |
| ELB-877 | Fixed | Image Viewer gpicview is no Longer in Demo Image | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem, Graphics | Low | No |
Description: In the demo images for BSP 2.8b1 the image viewer gpicview is not installed. Workaround: Remove adwaita-icon-theme from BAD_RECOMMENDATIONS when building the image with openembedded. |
| ELB-819 | New Feature | Provide LXQt Demo Image Similar to LXDE One | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Currently we use an LXDE/GTK+ based desktop for our demo images targetting modules which provide enough storage.
Moving this to a LXQt/Qt5 based desktop. This aids customers who want to start developing a Qt5 based application. |
| ELB-785 | New Feature | Remove snapd From Standard Images | Apalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30 | Miscellaneous Peripherals | Low | No |
Description: Remove snapd from standard images. |
| ELB-742 | Fixed | Build Failure When Building Image the Next Day Without Changes | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: After building an image completely successfully, building the same image the next day without any changes leads to an error "do_image_teziimg: Error executing a python function in exec_python_func()". Workaround: Make an unrelated change in any recipe to force recreation of the rootfs. |
| ELB-565 | New Feature | Improve angstrom-qt5-x11-Image by Using xinit to Start X | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Currently, we use an init script which starts X directly and then a Qt demo application.
This has some drawbacks, e.g. when one wants to start a touch calibration or the likes.
Use some readily available X startup system, e.g. xinit as a better base customers can build upon. Workaround: Please find a suitable systemd service in the following recipe:
http://git.toradex.com/cgit/meta-toradex-demos.git/tree/recipes-images/images/angstrom-qt5-x11-image.bb?h=rocko#n4 |
| ELB-414 | New Feature | Switch to zImage Instead of uImage | Apalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30 | Kernel | Low | No |
Description: Switch to the generic compressed Kernel image type (zImage) instead of the legacy U-Boot specific uImage format. Workaround: Please note that if one is updating from an earlier release one may have to manually fix the U-Boot environment to take this into account as mentioned on the community forum at https://www.toradex.com/community/questions/19860/bsp-28b2-fails-to-load-linux-kernel-due-to-uimage.html |
| ELB-832 | New Feature | Include hostapd IEEE 802.11 AP, IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator Daemon in Demo Builds | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem, Wi-Fi | Low | No |
Description: Include hostapd in demo builds. Note that this is only about the naked daemon without any configuration which depends on resp. requirements. So nothing of the hostapd will be automatically started by default. |
| ELB-826 | Fixed | Both fchdir() And fstat() Fail With EBADF When File Was Previously Opened with O_PATH Flag on T20/T30 | Colibri T20, Colibri T30, Apalis T30 | Kernel | Low | No |
Description: On Apalis/Colibri T20/T30 both fchdir() and fstat() fail with EBADF when the file was previously opened with the O_PATH flag. Workaround: Required patches have been backported to our downstream Linux kernel:
http://git.toradex.com/cgit/linux-toradex.git/log/?h=tegra-next |
| ELB-820 | New Feature | Enable Message when User Program Crashes | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Kernel | Low | No |
Description: Enable "user debug" which enables kernel messages when a user process crashes due to an exception. |
| ELB-802 | New Feature | Integrate New Build Number | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: As per amendment to http://developer.toradex.com/knowledge-base/toradex-software-versioning-convention |
| ELB-794 | New Feature | Update Bluetooth/Wi-Fi Backports to Latest Linux Kernel Mainline (LTS) Release | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Bluetooth, Buildsystem, Kernel, Wi-Fi | Low | No |
Description: We are currently using 4.11 which is not really an LTS release however we opted to do that because we were relying on it for certain later features for certain Wi-Fi solutions we wanted to support. It may make sense to stabilise on an LTS release for the future. Workaround: You may find our backports based on Linux kernel 4.14 here: http://git.toradex.com/cgit/backports-toradex.git/log/?h=toradex-4.14 |
| ELB-790 | Fixed | Apalis/Colibri T30 PWM Capped at 12.45kHz. | Colibri T30, Apalis T30 | PWM | Low | No |
Description: Apalis/Colibri T30 PWM was capped at 12.45kHz. We've increased it to 99.6kHz that can be further divided by integer divider. Workaround: PWM peripheral input clock value can be increased to a maximum of 48MHz. Valid clock values can be calculated pwm_clk = 408MHz/N, where N=<1 , 128.5> in 0.5 increments |
| ELB-778 | New Feature | Update to OpenEmbedded Rocko and Yocto Project 2.4 | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Update to the OpenEmbedded Rocko resp. Yocto Project 2.4 release. |
| ELB-775 | New Feature | Update the LXDE Recipes | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Update meta-lxde to build the latest LXDE sources. The latest lxpanel release doesn't work with our GTK+3. |
| ELB-656 | New Feature | fw-utils: Add Option to Display the Source Version | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Bootloader | Low | No |
Description: Add a -v parameter to fw_printenv/fw_setenv which outputs the U-Boot source version information. |
| ELB-636 | New Feature | Allow for Easier OpenEmbedded Machine Configuration | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Allow for easier OpenEmbedded machine configuration by our customers. |
| ELB-855 | New Feature | Apalis/Colibri T30/iMX6, Colibri iMX7 and Colibri VF50/VF61 Stable Release | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: This release is identical to the previous 2.7b4 release and has passed full validation and verification for Apalis T30, Apalis iMX6, Colibri T30, Colibri VF50, Colibri VF61, Colibri iMX6 and Colibri iMX7. |
| In this release we changed to use Ext4 file system by default. This could lead to non booting modules if a previously saved U-Boot environment is set to non-ext4. Please see the following issue for more details: http://developer.toradex.com/software/linux/linux-software/release-details?view=all&issue=27678 |
| ELB-749 | Fixed | Config Block Check During Update May Fail Depending on Hardware Area Boot Partition Size | Colibri iMX7, Apalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30 | Bootloader, Buildsystem | Low | No |
Description: The config block check aka check_configblock may fail during update depending on the size of the hardware area boot partition which may lead to the config block not getting properly migrated or updated if still using parts of the legacy update procedure. Workaround: Use U-Boot's built-in 'cfgblock create' functionality or use the Toradex Easy Installer where applicable. Alternatively find fixed legacy U-Boot update scripts in the -next branch of our meta-toradex-demo repository. |
| ELB-736 | Fixed | Define Standard Rootfs Mount Behaviour and Options | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Bootloader, Flash | Medium | No |
Description: The kernel does not know about rw,noatime. The string rw by itself
is valid, and to pass additional arguments rootflags=noatime can
be used. The kernel mounts ext3/ext4 file systems by default ro,
hence so far the kernel mounted the rootfs read-only. The init
manager systemd then remounts the rootfs after file system checking.
This makes sense and does not add measurable boot time. Let the
kernel explicitly mount ro on block device based rootfs.
The root mount flag noatime is only relevant when re-mounting
read-write, hence it needs to be present in /etc/fstab.
UBIFS used on raw NAND devices has no user space file checking,
hence there is no value to mount it in read-only first. Also mount
time for UBIFS is larger, and mounting first read-only and then
read-write has higher boot time (300ms, likely due to missing block
cache). Let the kernel explicitly mount rw on raw NAND based rootfs.
UBIFS has no atime support, hence no root mount flags needed. Workaround: The change to initially read-only mounted root file system on Apalis TK1 requires the U-Boot emmcargs environment variable to be adjusted to run NVIDIA's JetPack resp. L4T as documented here:
http://developer.toradex.com/knowledge-base/installing-nvidia-jetpack-with-l4t-on-apalis-tk1#Flashing_Latest_Boot_Loader |
| ELB-725 | Fixed | 'run update' Fails if the Rootfs is Exactly a Multiple of 64M | Apalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30 | Bootloader | Low | No |
Description: If an image creates a rootfs which is exactly a multiple of 64 MByte and then if one executes in U-Boot 'run update' the detection that all 64 MByte chunks have been flashed fails and the update never completes.
Note that the Toradex Easy Installer is not affected. Workaround: Check the last rootfs chunk on the update media and create a zero length chunk with incremented number, e.g.:
$ ls -l //colibri-imx6/
...
-rw-r--r--. 1 root root 67108864 Jul 12 15:13 root.ext3-106
-rw-r--r--. 1 root root 67108864 Jul 12 15:13 root.ext3-107
-rw-r--r--. 1 root root 48128 Jul 12 15:13 SPL
...
$ touch //colibri-imx6/root.ext3-108 |
| ELB-719 | Fixed | Power I2C Bus Communication Speed Should be Reduced to 100 KHz | Colibri T20, Colibri T30, Apalis T30 | I2C, Power Management | Low | No |
Description: Power I2C bus communication speed should be reduced to 100 KHz as our temperature sensor chip LM95245 is not rated for higher speeds. |
| ELB-705 | New Feature | Support Forcing 'cfgblock create' to Overwrite Existing Config Block | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Bootloader | Low | No |
Description: Support forcing U-Boot's 'cfgblock create' command to overwrite an existing config block e.g. using a -y parameter and therefore not prompting the user for easier scripting. |
| ELB-699 | Fixed | Eject Feature for Mass Storage Missing | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | SATA, SDIO/SD/MMC, USB | Low | No |
Description: Hitting the eject button either in the PCManFM file manager (pcmanfm) or the Disks gnome-disk-utility tool (gnome-disks) fails as follows due to the eject command line tool being missing:
Error ejecting media
Error ejecting /dev/sda: Error spawning command-line 'eject "/dev/sda"': Failed to execute child process "eject" (No such file or directory) (g-exec-error-quark, 8) (udisks-error-quark, 0) |
| ELB-693 | Fixed | Unify Behaviour When Config Block Is Missing | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Bootloader | Low | No |
Description: Currently various things may fail or behave strangely on certain modules if the config block is missing. Unify that behaviour by e.g. rather not allowing use of any features (e.g. Ethernet, RNDIS) at all in this case. Workaround: Use the 'cfgblock create' U-Boot command to restore the config block. Alternatively we implemented similar functionality into our Toradex Easy Installer. |
| ELB-681 | New Feature | Add support for LM816 (RTL8188EU) | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Wi-Fi | Low | No |

| ELB-657 | Fixed | Images: Configure systemd Without ACL Support | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Using ACL with ubifs seems to increase the likelihood of filesystem corruption. Since ACL is an optional features and unlikely necessary on an embedded system switch ACL off. |
| ELB-629 | Fixed | Module May Hang During Boot Upon Hardware Reset | Colibri T30, Apalis T30 | Bootloader, Kernel, Power Management | Low | No |
Description: Depending on its DVFS state right before hardware reset the Apalis/Colibri T30 module may hang during a subsequent boot. Software reset seems not affected. Workaround: Either power-cycle or make sure you are running at a higher DVFS state upon hardware reset. A fix for this called 'apalis/colibri_t30: improve vdd core pmic handling' may be found on our U-Boot 2016.11-toradex-next branch. |
| ELB-599 | New Feature | Update to Yocto Project Jethro Release 2.0.3 | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Update toradex-bsp-platform.git branch LinuxImageV2.6.1 to the latest of the jethro branches.
Note that we do not provide any binary demo images. |
| ELB-479 | New Feature | Over Temperature Notice Message | Colibri T30, Apalis T30 | Temperature Sensor | Low | No |
Description: As on our T30 designs there is a hardware over-temperature shut-off directly via PMIC we should check whether we could at least have an over temperature message shortly before that (e.g. 5 deg C). |
| ELB-650 | New Feature | New Versioning Scheme | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: We changed our versioning scheme. Our BSP demo image packages are now e.g. called Apalis-iMX6_LXDE-Image_2.7b2-20170410.tar.bz2. The Linux kernel will report e.g. the version number 4.1.39-2.7.2+gba2f75f and U-Boot will report e.g. 2016.11-2.7.2+g60021a4.
Details about the versioning can be found here: https://developer.toradex.com/knowledge-base/toradex-software-versioning-convention |
| ELB-639 | Fixed | Potential Systemd Hang on First Boot | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Systemd may hang upon first boot due to certain services like run-postinsts and opkg-configure triggering a configuration reload later causing dynamic device services like the dev-ttyS0 one to hang. Workaround: A fix has been implemented in our -next branch. |
| ELB-628 | New Feature | Deploy Mmc-Utils | Apalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30 | Buildsystem, Flash, SDIO/SD/MMC | Low | No |
Description: The mmc-utils allow e.g. inspecting the current health and life time estimation of the on-module eMMC. |
| ELB-627 | Fixed | HDMI Hot-Plugging Fails Configuring Desktop Output | Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | HDMI | Low | No |
Description: The udev rule /etc/udev/rules.d/hdmi.rules which should take care of this now fails with exit code 1. It looks like the RUN part of that rule should be reworked into its separate unit file to be spawned using SYSTEMD_WANTS. Workaround: Manually call xrandr to get the desired effect. |
| ELB-601 | Fixed | Update Meta-Angstrom to Latest Resulting in Using Linaro GCC 6 Compiler | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Recently Ångström switched to using the gcc 6 compiler in their 2016.12 aka morty branch. Update meta-angstrom to latest in order for us to also make use of the Linaro gcc 6 compiler. |
| ELB-586 | New Feature | Remove Unneeded RDEPENDS From Our Recipes | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Bitbake for some time checks what other packages a package depends on by e.g. examining the output of ldd of a binary or examining used interpreters in scripts.
So RDEPENDS are only needed for non obvious packages, e.g. such which get dynamically linked in code or packages providing data.
Cleanup our layers. |
| ELB-521 | New Feature | SoC Unique Number | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Miscellaneous Peripherals | Low | No |
Description: Most of our SoC have a manufacturer defined unique and not alterable number.
It's documented here: http://developer.toradex.com/knowledge-base/soc-unique-id-linux |
| ELB-397 | Fixed | Timeout Waiting for dev-ttys0.device on First Boot | Apalis T30 | Buildsystem | Low | No |
Description: Rarely a timeout waiting for dev-ttys0.device on first boot has been observed. Workaround: Just power-cycle again. |
| Known Issue for Colibri VF61: U-Boot 2016.11 Missing m4boot Command. |
| ELB-597 | Fixed | SysV Initscript Interference at Times Causing Networking Subsystem not to Start | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: With the move to morty all SysV initscripts have been installed which caused interference. This got fixed by finally getting rid of all SysV remnants. |
| ELB-556 | New Feature | Linux-ptp in BSP | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Apalis T30 | Buildsystem, Ethernet | Low | No |
Description: Include linuxptp in BSP image |
| ELB-517 | New Feature | Configure IPv6-in-IPv4 Tunnel (SIT Driver) as Module | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Colibri T20, Colibri T30, Apalis T30 | Ethernet | Low | No |
Description: The IPv6-in-IPv4 tunnel driver creates an additional network interface (sit0). To avoid confusion around that interface and since the sit interface is only used seldom the driver should be made available as a module. |
| ELB-511 | Fixed | PCIe Clock and Reset May not Conform to Specification | Apalis T30 | PCIe | Low | No |
Description: Our current PEX 8605 errata workaround violates the PCIe clock and reset specification should no PCIe switch be present as e.g. the case on Ixora. |
| ELB-509 | Fixed | eMMC Partition Limited to 4GB | Apalis T30 | Flash | Medium | No |
Description: Currently our update.sh script limits the partition size to around 4GB by default so even after our automatic resizing only 4GB of the 8GB of available eMMC space on the Apalis T30 2GB can be used. Workaround: Manually modify the EMMC_SIZE calculation for apalis-t30 in our update.sh script.
Our upcoming Toradex Easy Installer will no longer suffer from this limitation. |
| ELB-508 | Fixed | Update Scripts Limits rootfs Size to around 5GB when using TFTP | Apalis iMX6, Apalis TK1, Colibri T30, Apalis T30 | Flash | Medium | No |
Description: Our current update procedure reads the rootfs payload in pre split files of 64 MB size. The number of chunks is limited to 89 resulting in a maximum size of 5.5 GB. Workaround: - use the ums command in U-Boot to export the modules eMMC as a mass storage device.
- deploy a minimum rootfs and install the 'big' payload after booting into Linux |
| ELB-507 | Fixed | Update Scripts Limits rootfs Size to 4GB | Apalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30 | Flash | Medium | No |
Description: Our current update procedure requires the rootfs payload to fit in one file on a FAT filesystem. This limits its usable size to 4GB. Workaround: - use the ums command in U-Boot to export the module's eMMC as a mass storage device
- deploy a minimum rootfs and install the 'big' payload after booting into Linux
- update over tftp, but see http://developer.toradex.com/software/linux/linux-software/release-details?view=release-roadmap&&issue=21229 |
| ELB-506 | New Feature | Update U-Boot for all Modules to be Based on U-Boot 2016.11 Release | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Bootloader | Low | No |
Description: Updates our downstream U-Boot to 2016.11.
This also includes a newer UBI/UBIFS stack which fixes issues such as "Error reading superblock on volume 'ubi0:rootfs' errno=-22" when using UBI fastmap in U-Boot. |
| ELB-505 | New Feature | OpenEmbedded: Update to the Morty Release | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Update our layers and the OE setup to support and use the morty release aka. Yocto Project 2.2. |
| ELB-492 | Fixed | SSH X11 Forwarding is Disabled by Default | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Ethernet | Low | No |
Description: In later OE versions the default SSH config changed so that X11 forwarding is not allowed.
$ ssh -X root@192.168.10.185
X11 forwarding request failed on channel 0 Workaround: Edit /etc/ssh/sshd_config to include
X11Forwarding yes |
| ELB-440 | Fixed | DHCP Server on USB RNDIS Announces Module as Router | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | USB | Low | No |
Description: When connecting the module using USB device connection, the module provides an IP address via it's own DHCP server. The DHCP server uses DHCP Option 3 (Router) to announce itself as router which can lead to internet connection interruption on the host. |
| ELB-434 | Fixed | OE Build on Distro with GCC 6 Host Toolchain | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Newer distros like e.g. Fedora 24 use GCC version 6 as the host (native) toolchain.
Our jethro based Yocto project build is not able to build the needed native tools, among them the cross compiler on such distros. Workaround: Use a lightweight container with an older distro as documented on our developer website. |
| ELB-420 | Fixed | Move to GTK+ 3 in Demo Image | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem, Graphics | Low | No |
Description: OE migrated the sato image to GTK+ 3. This includes pcman-fm with its libfm.
As lxpanel is using libfm we have to follow here or provide our own pcman-fm/libfm recipes.
If we move to GTK+ 3 I guess we should do it with all GTK+ based software. e.g all of lxde/lxdm (which may have some issues), the GPIOconfig tool and tegrastats-gtk. |
| ELB-417 | New Feature | Distro Boot Integration | Colibri iMX7, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Bootloader, SDIO/SD/MMC, USB | Low | No |

Description: Udisks development has stalled in 2014, udisks2 seems to be the successor.
According to the OE recipes udisks2 also has less dependencies (notable lvm2, which adds almost 3.2MiB to the image and is not commonly used in embedded systems as well as sg3-utils, another 1.1MiB).
Udisks2 also has a command line utility see: https://zeth.net/2014/05/28/modern_mounting_with_udisks2.html. |
| ELB-480 | Fixed | 100mW Power Saving by Changing Default Settings of Multiplexed Pins of Camera Input | Colibri T30, Apalis T30 | Bootloader | Low | No |
Description: Changing the default settings of multiplexed pins of the camera input allows saving up to 100mW of power. |
| ELB-443 | New Feature | GCC-6 Usable as the Crosstoolchain | Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Kernel | Low | No |
Description: As OE moves to GCC-6 we should provide our NVIDIA Kernel sources in a way that they can be built with gcc 6.
This would allow customers taking our BSP and using it with a later Yocto project release. |
| ELB-438 | New Feature | EDID Causing Kernel Panic on T30 | Colibri T30, Apalis T30 | HDMI, Kernel | Low | No |
Description: Certain EDID from HDMI screens are causing a kernel panic upon boot on T30. |

Description: Separate the 'one size fits all' meta-toradex layer into BSP layers by SoC vendor and a software layer for the demo images. |
| ELB-471 | New Feature | Apalis/Colibri T30/iMX6 Stable Release | Apalis iMX6, Colibri iMX6, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: This release is identical to the previous V2.6 Beta 2 release and has passed full validation and verification for Apalis T30, Apalis iMX6, Colibri T30 and Colibri iMX6. |
| ELB-403 | Fixed | Florence On-Screen Keyboard not Showing Labels on Special Keys | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Colibri T20, Colibri T30, Apalis T30 | Miscellaneous Peripherals | Low | No |
Description: The labels on special keys such as caps lock, enter or tab are missing. Workaround: A fix is already available on the V2.6-next Meta-Toradex branch. |
| ELB-318 | New Feature | Add Driver for LM006 USB Wi-Fi Dongle to Standard Image | Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Colibri T20, Colibri T30, Apalis T30 | USB, Wi-Fi | Low | No |
Description: Add support for the LM Technologies LM006 Wi-Fi USB dongle to our standard images. |
| ELB-312 | Fixed | USB Detection Issue & Low Transfer Speed | Colibri T30, Apalis T30 | USB | Low | No |
Description: USB detection may fail especially on the OTG port plus the transfer speed may be rather low. Workaround: Reverting http://git.toradex.com/cgit/linux-toradex.git/commit/?h=tegra&id=629b91fa046df5213ed3312d2e2b8683e6bdd70c helps but reintroduces issue #6422. |
| ELB-301 | Fixed | Rare I/O Error on eMMC | Colibri T30, Apalis T30 | SATA, SDIO/SD/MMC | Low | No |
Description: Very rare occurrence of eMMC issues as shown below in combination with extensively heavy SATA and/or SD card stress testing: I/O error, dev mmcblk0 Workaround: Avoid extensively heavy SATA and/or SD card stress testing. Usually power-cycling brings the system back to life. |
| ELB-297 | Fixed | Slow Memory Copy | Colibri T30, Apalis T30 | RAM | Low | No |
Description: Libc based memory copy recently slowed down by almost a factor of two. Workaround: Use one of our V2.1 based BSPs which did not exhibit this issue. |
| ELB-226 | Fixed | Race Condition in USB OTG Device/Host Detection on Ixora | Apalis T30 | USB | Low | No |
Description: On Ixora with set jumper JP2 the lower X8 USB host port (shared with the X9 micro USB port) is not reliably working. There seems to be a race condition in NVIDIA's USB OTG driver concerning the loading and binding of the USB device gadget driver which prevents Apalis USBO1 being operational in host mode. Workaround: Disconnecting the USB device, removing the jumper JP2, connecting a USB micro cable to a PC, disconnecting the same again, jumpering JP2 again and connecting the USB device again should remedy the issue.
Alternatively booting with JP2 removed and only connecting JP2 after boot also works. |
| ELB-139 | New Feature | T30 U-Boot Framebuffer | Colibri T30, Apalis T30 | Bootloader, RGB | Low | No |
Description: No framebuffer support in U-Boot for Colibri/Apalis T30, therefore splashscreen in U-Boot is not possible. Workaround: Use splashscreen support in Linux. |
| ELB-106 | New Feature | BCT Memory Optimisation | Apalis T30 | Bootloader, RAM | Low | No |
Description: Currently DDR3L RAM is running at 533MHz. Further optimisations to achieve 800MHz speeds are required. |
| ELB-275 | Fixed | Floating Point Exception using nv_omx_h264enc | Colibri T30, Apalis T30 | Video Codecs | Low | No |
Description: One might get the following floating point exception when using nv_omx_h264enc either trying to transcode MPEG transport streams or encode video stream coming from a Gstreamer appsrc:
+NvxVideoEncoderSetNvMMAttributes-NvxVideoEncoderSetNvMMAttributesFloating point exception Workaround: If you experience this exact issue please downgrade to our V2.3 Beta 3 (October 31, 2014) release for now.
We opened a ticket with NVIDIA and are working with them to get this resolved as soon as possible. |
| ELB-269 | Fixed | Rare I/O Error on eMMC | Colibri T30, Apalis T30 | Flash, Kernel, SDIO/SD/MMC | Medium | No |
Description: Rare occurrence of eMMC issues as shown below can lead to read-only root file system or even non-booting systems:
I/O error, dev mmcblk0 Workaround: Usually power-cycling brings the system back to life. The tegra-next branch of our Linux kernel source repository contains a fix for this. |
| ELB-152 | Fixed | Different Mountpoint Names when Mounted at Boot vs. Mounted at Runtime / with Diskutility | Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Colibri T20, Colibri T30, Apalis T30 | SATA, SDIO/SD/MMC, USB | Low | No |

| ELB-1450 | New Feature | Implement Optional MMC UHS Support | Apalis T30 | SDIO/SD/MMC | Low | No |
Description: Implement optional MMC UHS support (enable using mmc_uhs=1 kernel command line parameter, requires V1.1A or later HW). |
| ELB-255 | Fixed | X-Server Rotation Broken | Colibri T20, Colibri T30, Apalis T30 | Graphics, HDMI, LVDS, RGB, VGA | Low | No |
Description: XRandR based rotation as described on the following article on our developer website is broken since our V2.1 releases:
http://developer.toradex.com/knowledge-base/x-server-%28linux%29#Rotation Workaround: Please revert to one of our older V2.0 based releases for now. |
| ELB-236 | Fixed | Memory Leak during Gstreamer Video Playback | Colibri T30, Apalis T30 | Multimedia | Low | No |
Description: Several hours of gstreamer streaming aborts due to memory leak in nvvidconv gstreamer plugin. Workaround: Under certain circumstances using an older NVIDIA L4T R16.3 based BSP might be feasible until NVIDIA releases a fix. |
| ELB-103 | Fixed | USB Low-Speed Issue | Colibri T30, Apalis T30 | USB | Low | No |
Description: Certain low-speed USB devices are not detected correctly when plugged into a running system. Workaround: Use a hub or ensure device is connected before power up. A driver fix will be made to correct this behaviour. |
| ELB-234 | Fixed | Analogue Audio Codec Disappearing during Reboot | Colibri T30, Apalis T30 | Analog Audio | Low | No |
Description: Analogue audio codec disappearing during reboot particularly if previously used for audio recording. Workaround: Power-cycling should help. Alternatively wait for us to backport respective Linux kernel driver fixes. |
| ELB-138 | New Feature | U-Boot Gigabit Ethernet | Apalis T30 | Bootloader, Ethernet | Low | No |
Description: No support for Ethernet on Apalis T30 in U-Boot. Workaround: Use an Asix based USB to Ethernet dongle if you need Ethernet support in U-Boot. |
| ELB-227 | Fixed | PCIe and with it Gigabit Ethernet Rarely Unavailable after Boot | Apalis T30 | Ethernet, PCIe | Low | No |
Description: PCIe is rarely unavailable after Boot on the Apalis T30 module indicated by the following kernel message(s) during boot: 'PCIE: port 0: link down, ignoring', 'PCIE: port 1: link down, ignoring' and/or 'PCIE: port 2: link down, ignoring'. Gigabit Ethernet is also affected by this issue as its controller chip is connected through PCIe indicated by the following missing kernel message during boot: 'igb 0000:01:00.0: Intel(R) Gigabit Ethernet Network Connection' resp. 'igb 0000:07:00.0: Intel(R) Gigabit Ethernet Network Connection'. We are working together with NVIDIA to solve this issue as it seems to be a hardware issue of the PCIe controller in the T30 SoC. Workaround: Currently the only thing known to help is power-cycling or sometimes also doing a reset. As the issue is probably dependant on operating conditions such as temperature varying this might also help. We are working together with NVIDIA to find a good software workaround for this issue. |
| ELB-1443 | New Feature | Camera Serial Interface (CSI-2) | Apalis T30 | CSI | Low | No |
Description: Implement initial CSI-2 support for the Aptina AS0260 YUV sensor. |
| ELB-237 | Fixed | Rare I/O Error on eMMC | Apalis T30 | Flash, Kernel, SDIO/SD/MMC | Medium | No |
Description: Rare I/O error observed on eMMC which might prevent successful boot. Workaround: Power-cycle usually helps. Alternatively use a later custom kernel or await our official release thereof. |
| ELB-197 | Fixed | Disabling HDMI Display Controller via modedb Kernel Arguments | Colibri T20, Colibri T30, Apalis T30 | Graphics, HDMI | Low | No |
Description: Currently when disabling the HDMI display controller by specifying the modedb option 'video=tegrafb1:off' from within U-Boot as Linux kernel boot argument the Tegra X driver complains with 'failed to initialize the display controller library' and refuses to start X at all. Workaround: As a workaround one can remove the HDMI display controller's device node 'rm /dev/tegra_dc_1' and restart LXDM 'systemctl restart lxdm' from within Linux. |
| ELB-195 | Fixed | U-Boot TFTP/NFS Booting via USB-to-Ethernet | Colibri T30, Apalis T30 | Bootloader, Ethernet | Low | No |

| ELB-141 | New Feature | Add Apalis MXM Pin Descriptions to the GPIO Config Tool | Apalis T30 | GPIO | Low | No |
Description: Add Apalis MXM pin descriptions to the GPIO config tool. Workaround: None. |
| ELB-4066 | Known Issue | SODIMM_45 Powers Down Colibri T30 Instead of Wake up From Suspend | Colibri T30, Apalis T30 | Power Management | Medium | No |
Description: The pin SODIMM_45 (WAKE1) is usually used for waking up a module from suspend. However transitioning SODIMM_45 from 0V to 3.3V triggers the module to power down. Workaround: Change the logind configuration to ignore 'power key' key presses.
Set in /etc/systemd/logind.conf:
HandlePowerKey=ignore |
| ELB-3519 | Known Issue | Watchdog reset on Colibri T30 leads to Freeze on Downstream Kernel | Colibri T20, Colibri T30, Apalis T30 | Watchdog | Low | No |

Description: Sync U-Boot DTS with the Linux mainline |
| ELB-2504 | Feature Request | [U-Boot] PCI / PCIe related dts issues/cleanup | Apalis TK1, Apalis T30 | Bootloader | Low | No |
Description: U-Boot maintainer is adding new checks for the format of PCI/PCIe nodes in DTs, which will bring mainline U-boot slightly closer to being in-line with current Linux kernel mainline. See reference at https://lists.denx.de/pipermail/u-boot/2020-February/399741.html
Toradex will sync with the mainline Linux device tree PCI nodes. |
| ELB-1280 | Known Issue | STMPE811 ADC: Timeouts And Reads From False Channels | Colibri T30, Apalis T30 | Analog Inputs | Low | No |
Description: Timeouts and reads from false channels may be observed when using STMPE811 ADC. Workaround: An improved driver is available on the toradex_4.9-2.3.x-imx-next branch applicable for Apalis iMX6, Apalis iMX8, Colibri iMX6 and Colibri iMX8X. |
| ELB-1184 | Known Issue | Video Playback on Parallel RGB Display not Possible Under Certain Circumstances | Colibri T30, Apalis T30 | Multimedia, RGB, USB | Low | No |
Description: Video playback with nvgstplayer is not working when booted with a plugged-in USB webcam. Workaround: Plugging-in the webcam after the system booted up may alleviate the issue. |
| ELB-1183 | Known Issue | Boot Error "commit machine-id" | Colibri T20, Colibri T30, Apalis T30 | Kernel | Low | No |
Description: There may be a boot error reported concerning "commit machine-id". This is caused by an incompatibility between later systemd version and the downstream NVIDIA L4T R16.5 based Linux kernel 3.1.10. However, no further adverse effect has been discovered. Workaround: Running a mainline based Linux kernel does not exhibit this issue. |
| ELB-1161 | Known Issue | Spurious Errors Shown During Legacy Update Procedure | Apalis TK1, Colibri T30, Apalis T30 | Bootloader | Low | No |
Description: During the legacy update procedure running e.g.:
run setupdate
run update
May show the following spurious errors which can usually be ignored:
MMC read: dev # 0, block # 16383, count 1 ... MMC: block number 0x4000 exceeds max(0x2000)
0 blocks read: ERROR
This has to do with various eMMC parts featuring different eMMC hardware boot area partition sizes which get probed by the legacy U-Boot update scripts potentially showing missleading error messages. Workaround: Just ignore such error messages during the legacy update procedure. |
| ELB-1129 | Known Issue | Apalis T30: USB OTG Device/Host Mode Switching Causing Kernel Lock-up | Apalis T30 | USB | Low | No |
Description: If a USB 2.0 micro-B USB-OTG cable is plugged in the USB 3.0 micro-B socket, the connection is mechanically rather loose and may cause a lot of ID change interrupts in the kernel triggering going from host mode to suspended mode. This leads the kernel sometimes to lock itself up. Workaround: Fix the USB-OTG cable so that it cannot move around causing spurious interrupts. |
| ELB-1120 | Feature Request | Add Modules Parameter to MWiFiex Driver For Single Antenna Operation | Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30, Apalis iMX8 | Wi-Fi | Low | No |
Description: For single antenna set single_rf=0x01 |
| ELB-1116 | Feature Request | T20/T30 Internal Video DAC Output | Colibri T20, Colibri T30, Apalis T30 | Graphics, VGA | Low | No |
Description: The T20 SoC internal video DAC output is unsupported by NVIDIA's L4T Linux SW stack our BSP is based on. The T30 SoC does not even support any internal video DAC functionality according to NVIDIA's latest specification. Workaround: Use an external video DAC on the carrier board similar as to what may be found on our Colibri Evaluation board, Iris or Aster. |
| ELB-1111 | Known Issue | UART Input Overrun | Colibri T20, Colibri T30, Apalis T30 | UART | Low | No |
Description: Certain use-cases may cause UART input overruns. Workaround: Disabling DMA may help but ultimately this got fixed in the Linux kernel 4.19. |
| ELB-1025 | Known Issue | Native compilation using arm-angstrom-linux-gnueabi-gcc not working with GCC 7.2 and above | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Apalis T30 | Buildsystem | Low | No |
Description: Currently native Compilation is not working in the regular Bsp (version > 2.8) due to a mismatch of GCC libraries. Workaround: Do cross-compilation or create a custom image with GCC being pre-installed.
IMAGE_INSTALL_append = " packagegroup-sdk-target" |
| ELB-1003 | Known Issue | HDMI HDA Audio Issues | Colibri T20, Colibri T30, Apalis T30 | Digital Audio, HDMI | Low | No |
Description: HDMI HDA resp. I2S audio may not work with certain screens depending on available display modes and pixel clock frequencies. HDMI HDA resp. I2S audio may also not work after hot-plugging. Workaround: Make sure to use vidargs selecting a HDMI audio capable pixel clock frequency. Do not hot-plug resp. power-cycle after plugging in HDMI. If you keep having issues try another brand/model screen. |
| ELB-1002 | Known Issue | U-Boot Splash Screen Not Working | Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Bootloader | Low | No |
Description: On Colibri T20 and Apalis/Colibri T30 the famebuffer console output is shown rather than an image splash screen due to differences in graphics stacks. On Apalis TK1 there is currently no framebuffer support. Workaround: You may use a Linux kernel or user space splash screen. |
| ELB-977 | Known Issue | Concurrent Dual CSI-2 Camera Failing | Apalis T30 | CSI | Low | No |
Description: Concurrent dual CSI-2 camera is currently failing on Apalis T30. It is working fine on Apalis TK1. Workaround: Apalis TK1 would support this. |
| ELB-976 | Known Issue | Year 2038 Issue | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Kernel, Miscellaneous Peripherals, RTC | Low | No |
Description: On 32-bit systems, Linux uses a 32-bit signed integer type 'time_t' to represent the time at various locations. It gives the time as seconds relative to 1970.
The time_t type wraps at "2038-01-19 03:14:07", so all users of time_t likely fail when a type_t instance is set to a timer after that date.
This issue is applicable to all 32-bit systems and will be fixed in the mainline eventually. |
| ELB-975 | Known Issue | LXDE, Moved Desktop Icons are not Redrawn Automatically | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | RGB | Low | No |
Description: If one moves desktop icons in LXDE they are not redrawn automatically. Workaround: Click anywhere on the desktop and the icons reappear at the position they have been moved to. |
| ELB-950 | Known Issue | ETH1_LINK LED Only Showing Gigabit Link State | Apalis TK1, Apalis T30 | Ethernet | Low | No |
Description: The ETH1_LINK LED is only lighting up if a Gigabit link is established. If the link is only 10 Mbps or Fast Ethernet the LED currently does not show any link. |
| ELB-948 | Feature Request | Add gatttool to Demo Images | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30 | Bluetooth | Low | No |

| ELB-938 | Known Issue | systemd udisks2 Linux Kernel Incompatibility Causing Power-Off After Unmount of USB Mass Storage Devices to Fail | Colibri T20, Colibri T30, Apalis T30 | Kernel, SATA, SDIO/SD/MMC, USB | Low | No |
Description: An incompatibility between the downstream Linux kernel 3.1.10 and systemd in conjunction with udisks2 is causing power-off after unmount of USB mass storage devices to fail as follows:
root@apalis-t30:~# udisksctl power-off -b /dev/sda
Error powering off drive: Error opening /dev/sda: Device or resource busy (udisks-error-quark, 0)
Note: As a side effect subsequently plugged in USB mass storage devices may also get increasing device node names even though previous ones already got unplugged beforehand (e.g. sdb, sdc etc.). Workaround: Do not use systemd or upgrade to the mainline Linux kernel. |
| ELB-911 | Known Issue | Playing Wavefile on Apalis T30 using Java makes the Kernel freeze | Colibri T30, Apalis T30 | Analog Audio | Low | No |
Description: This has initially been observed using JDK 1.8.0_121 on our stable BSP 2.6 but the system still does freeze as of JDK 1.8.0_152 on BSP 2.8b3.
There seems to be a race condition within the clocking and/or DMA subsystems caused by Java's rather special way of doing ALSA. Workaround: Playing MIDI files instead seems to work. Alternatively, using the mainline Linux kernel playing a wavefile using the same Java versions also works just fine. |
| ELB-880 | Feature Request | Add a Qt5 Based Browser to the LXQt recipe | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30, Apalis iMX8 | Browser, Buildsystem | Low | No |
Description: Currently there is no suitable browser which fits in the LXQt recipe.
Find a suitable browser and integrate it into the layers. |
| ELB-860 | Known Issue | LM816 Does Not Support AP Mode | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Wi-Fi | Low | No |
Description: Currently access point aka ap mode is not supported on the LM816 Wi-Fi USB dongle. |
| ELB-857 | Known Issue | Broken ath10k Qualcom Atheros QCA988x Firmware in 2.8b1 | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Wi-Fi | Low | No |

| ELB-856 | Known Issue | LM816 Low Bandwidth in BSP 2.8b1 Release | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Wi-Fi | Low | No |
Description: LM816 Wi-Fi speed is limited to 1 Mbit/s rx/tx. Workaround: Updating to a later Wi-Fi backports may help but only marginally. |
| ELB-770 | Known Issue | Updated Recipe for devmem2 Might Cause LIC_FILES_CHKSUM Error | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: An existing OE setup updated to 2.7b4 might show the following error:
ERROR: devmem2-1.0-r7 do_populate_lic: QA Issue: devmem2: The LIC_FILES_CHKSUM does not match for file://devmem2.c;endline=38;md5=a9eb9f3890384519f435aedf986297cf
This is caused by a file allready in your download directory. Workaround: Execute the following:
bitbake -c cleanall devmem2 |
| ELB-767 | Known Issue | Legacy Ubuntu 12.04 Not Compatible With Our Update Script | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: Using legacy Ubuntu 12.04 is not compatible with our update script due to too old split implementation in coreutils. Coreutils needs to be 8.16 or later. Workaround: Have a look at the various suggestions given in our community: https://www.toradex.com/community/questions/15912/apalis-module-update-script-fails.html |
| ELB-757 | Known Issue | /etc/profile Not Properly Sourced Upon Graphical Login | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Graphics | Low | No |
Description: For unknown reason /etc/profile does not get properly sourced upon graphical login. Not only does the shell prompt look strange in a desktop terminal but fw_setenv also does not work as it is missing some configuration:
When using fw_setenv from a modules desktop environment one gets an error indicating that the boot partition is not writable.
sh-4.3# fw_setenv x z
Write error on /dev/mmcblk0boot0: Operation not permitted
Error: can't write fw_env to flash Workaround: Revert to a serial terminal or just manually source /etc/profile which will also properly configure fw_setenv:
sh-4.3# . /etc/profile
root@apalis-t30:~# |
| ELB-702 | Known Issue | NTSC Decoding With ACA (ADV7280 Resp. ADV7280-M) | Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Camera Parallel Interface, CSI | Low | No |
Description: While the ADV7280 as found on our new Analogue Camera Adapter should allow for NTSC decoding it currently seems not to work properly. The same issue has been observed using the CSI version ADV7280-M on Apalis T30/TK1. Workaround: Apalis/Colibri iMX6 is known to work with NTSC input on ACA. The same applies to using the CSI version ADV7280-M on Apalis iMX6. |
| ELB-692 | Known Issue | USB Memory Sticks Not Working Reliably in U-Boot | Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30, Apalis iMX8 | Bootloader, USB | Low | No |
Description: Unfortunately U-Boot's USB functionality may be rather limited. Workaround: Usually using a different brand/model USB stick may prove working just fine. Alternatively USB SD card readers seem to work rather better. |
| ELB-674 | Known Issue | Sometimes the RTC Driver Recovers Invalid Date/Time from the External RTC | Colibri T20, Colibri T30, Apalis T30 | RTC | Low | No |
Description: After the RTC has been under-powered, some RTC deliver invalid date/time. The external RTC currently shipped on Toradex evaluation boards has a oscillator fail bit which indicates when RTC does not contain a valid date/time. |
| ELB-638 | Known Issue | U-Boot: Certain USB Memory Sticks May Not Work Reliably Behind a USB Hub | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Bootloader | Low | No |
Description: Certain USB memory sticks may not work reliably behind a USB hub. Please note that some (Apalis) if not all (Colibri) USB sockets on our evaluation boards are always behind an on-carrier USB hub. Workaround: Switch to a different carrier board without an on-carrier USB hub like Iris or Ixora, try a different brand USB memory stick or revert to a completely different update media like an SD card. |
| ELB-602 | Known Issue | Colibri T30 May Freeze on Concurrent SD Card and Multiple USB Devices Stress Testing | Colibri T20, Colibri T30, Apalis T30 | SDIO/SD/MMC, USB | Low | No |
Description: In use cases involving all 3 USB host controllers with USB hubs connected to the OTG as well as the regular host port with USB keyboard/mouse resp. USB-to-serial-adapter connected plus an SD card the Colibri T30 may freeze upon stress testing. Workaround: Only use two USB host controllers. Ethernet already uses one of them. Use an external USB hub for further USB ports.
Alternatively if you don't use Ethernet you may disable it as follows: 'echo 0 > /sys/class/gpio/gpio232/value'.
We didn't see these issues when using mainline. |
| ELB-575 | Known Issue | LX Panel, CPU Usage Monitor & Confusing Display Due to Dynamic Full Scale | Apalis TK1, Colibri T30, Apalis T30 | CPU | Low | No |
Description: The LX Panel gives an overview of the current CPU Usage by providing a rolling chart of the last minute.
Full Scale of the chart is what all the CPU cores which are currently on could compute at the current CPU speed.
Since the CPU speed adapts to the current workload full scale is not a constant.
On top of that on some modules CPU cores are dynamically switched on or off depending on the current computing load. This can lead to the confusing effect that increasing the load by a little can lead to a decreased load displayed in the 'CPU Usage Monitor' because on additional core is switched on. |
| ELB-571 | Known Issue | Memory Corruption with ext4 Filesystem | Colibri T20, Colibri T30, Apalis T30 | Flash, Kernel, SATA, SDIO/SD/MMC, USB | Medium | No |
Description: NVIDIA's downstream L4T kernel our BSPs are based on has issues with the ext4 file system. Workaround: Use the ext3 file system instead. |
| ELB-554 | Known Issue | Exar PCIe UART driver does not work on Apalis T30 | Apalis TK1, Apalis T30 | PCIe, UART | Low | No |
Description: Exar PCIe UART driver backport (or official Exar driver) does not work on Apalis T30 |
| ELB-539 | Known Issue | First Boot, Rootfs Expansion Affects System Performance | Apalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30 | Flash | Medium | No |
Description: On first boot the rootfs partition gets expanded to the full size of the partition it lives in. This resizing process adversely affects system performance for the first few minutes until completed.
Compare with:

| ELB-530 | Known Issue | IrDA not Implemented | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | IrDA | Low | No |
Description: IrDA requires specially modulated UART signals. While at least some of the UART drivers can be compiled or configured to use IrDA we didn't test if this would actually work. |
| ELB-526 | Feature Request | SGTL5000 Audio Multi Instance Codec Driver | Apalis TK1, Colibri T30, Apalis T30 | Analog Audio | Low | No |
Description: The SGTL5000 driver in the Linux Kernel currently only supports one codec.
The driver would need amending so that multiple codecs can be used. The issue is the statically created VDDD_LDO regulator. |
| ELB-463 | Known Issue | SPDIF not Working | Colibri T20, Colibri T30, Apalis T30 | Digital Audio | Low | No |
Description: SPDIF is not working in the V2.6 beta 2 release. This is a regression against older releases. |
| ELB-407 | Known Issue | Busybox and UTF-8 Chars in Filenames | Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Buildsystem | Low | No |
Description: For many utils (e.g. ls) we use busybox in our image.
These utils in the used busybox version display chars outside of the 7 bit ASCII range as a '?' even if the locale is set correctly and the system uses e.g. UTF-8. Workaround: Just enable UNICODE in the BusyBox configuration and re-compile. |
| ELB-399 | Known Issue | Gstreamer/Nvgstplayer Memory Leak | Colibri T30, Apalis T30 | Multimedia, Video Codecs | Low | No |
Description: Each iteration of a movie H264 playback using gstreamer/nvgstplayer allocates a queue via NvMMQueueCreate(phQueue=0x4225f318, max_entries=32, entry-size=224, thread_safe=1) inside NVIDIA's binary only libnvmm_utils.so library which is never freed (such a function creates three pointers of total size 7392 + 28 + 32). Most probably there is a missing NvMMQueueDestroy() somewhere in the decoder handling. Workaround: The easiest workaround would be to spawn a new gstreamer process for every movie being played as destroying that process after the playback will explicitly free any memory even if not previously implicitly having been freed.
Alternatively our partner Antmicro hacked up a custom libnvmm_utils.so wrapper library to be loaded by LD_PRELOAD which may intercept NvMMQueueCreate() calls and adaptively revert to a static queue in order to prevent any memory leaks. While such a solution will of course be highly use-case dependant it should fully fix any leaking.
Further investigation on NVIDIA's side is pending. |
| ELB-338 | Feature Request | Linux Kernel Splash Screen Doesn't Work on HDMI Output | Apalis iMX6, Colibri iMX6, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | HDMI | Low | No |
Description: Using a Linux logo be it the penguins or a custom one as e.g. explained at http://developer.toradex.com/knowledge-base/splash-screen-linux does not work on the HDMI output.
When the kernel sets up the display driver it first sets up VGA resolution subsequently doing DDC/EDID and then sets the final resolution. While the Logo is drawn during the VGA resolution setting it is lost later on. Workaround: On Apalis/Colibri iMX6 one may use the U-Boot splash screen on HDMI output as well. |
| ELB-313 | Known Issue | Incompatibility Between L4T Linux Kernel and iproute2-ss140804 | Colibri T20, Colibri T30, Apalis T30 | CAN | Low | No |
Description: There exists an incompatibility of sorts between the older L4T Linux kernel version our Tegra BSPs are based on and the newer iproute2-ss140804 from our V2.4 BSPs leading to errors as follows:
root@apalis-t30:~# ip -details link show can0
RTNETLINK answers: Invalid argument
Cannot send link get request: Invalid argument Workaround: Either downgrade to iproute2-ss131122 from our V2.3 BSPs or simply drop specifying a particular interface (e.g. use 'ip -details link show' instead). |
| ELB-262 | Feature Request | Xinput-Calibrator May Fail When Axis Are Swapped | Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30 | Resistive Touch | Low | No |
Description: Xinput-calibrator may fail when axis are swapped. Usually a single axis swapped works however when there are multiple ones swapped the algorithm may fail getting any useful calibration coefficients. Workaround: Avoid swapped axis e.g. by fixing the hardware wiring or pre-configure them via e.g. /etc/X11/xorg.conf as follows:
Section "InputClass"
Identifier "ResistiveTouch"
MatchProduct "stmpe-ts"
Option "SwapAxes" "1"
