BSP Layers and Reference Images for Yocto Project Issue Tracker

 

The following table contains known issues, scheduled bug fixes, and feature improvements for the Toradex BSP Layers and Reference Images for Yocto Project.

The tickets are split into two major states:

  • Submitted (open): new features and bug fixes for BSP versions that have not yet been released. They may be scheduled for a specific release version; not planned; or in our backlog. All of them have one of the following states:
    • Known Issue: a bug or unexpected behavior that has been reported and is pending a fix. Once fixed, the status will transition to Fixed.
    • Feature Request: a new feature that may be added to a future release. Once released, the status will transition to New Feature.
  • Released (closed): new features and bug fixes for BSP versions that have already been released. All of them have one of the following states:
    • Fixed: a bug that has been fixed and released.
    • New Feature: something that didn't exist before and was added to a new release.


Any schedules are not guaranteed but reflect the current planning. The planning could be shifted due to priority changes.

Issues that are scheduled for a specific version will be integrated into the mentioned version of the BSP.

We will update this table continuously in order to always provide the latest state of our development plan. Please see also the Linux Support Strategy to learn more about the different releases.

6.2.0 (Release date: 2023-03-31)
Embedded Linux BSP Q1 2023 Quarterly Release. Learn more on https://www.toradex.com/news/bsp-layers-reference-images-yocto-project-6-2-0-quarterly
ELB-4989FixedNAND Bad Block Table Is Corrupted At Every BootColibri iMX7, Colibri T20, Colibri VF50, Colibri VF61Flash, KernelLowNo

Description: The NAND bad block table is getting corrupted at every boot because of a configuration mismatch between U-Boot (using OOB data for bad blocks) and Linux (using an in-band table at the end in the last 2 NAND blocks). This could potentially cause data loss in case a bad block is reused and the error is not recoverable with ECC.

Workaround: Set `CONFIG_SYS_NAND_USE_FLASH_BBT=y` in U-Boot configuration.

Description: We switched from CRDA to direct loading of the Wi-Fi regulatory domain database in-kernel.

ELB-1047Fixediptables Not Supported by Default Linux Kernel ConfigurationColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30EthernetLowNo

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

2.8b5 (Release date: 2018-12-28)
ELB-1082FixedCapacitive Touch Not Working ReliablyColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Capacitive TouchLowNo

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-1081FixedCapacitive Touch not Working on AsterColibri T20, Colibri T30Capacitive TouchLowNo

Description: Touchscreen with 7" Capacitive Touch Display does not work when used on an Aster carrier board with a Colibri T20/T30 module.

ELB-1051New FeatureUpdate Wi-Fi Backports to 4.18Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Wi-FiLowNo

Description: Update Wi-Fi Backports to 4.18

ELB-965FixedLegacy Update Procedure May Fail on Debian Stretch or Arch LinuxColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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-951FixedDo Not Enforce Building 32-Bit Host BinariesColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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-932New FeatureImage Features do not Work with Toradex Console ImageColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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-915New FeatureDisable Display Backlight before Starting LinuxColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Bootloader, RGBLowNo

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-493FixedSupport MXM/SODIMM Pin Numbers to Get/Set GPIOsColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30GPIOLowNo

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-258New FeatureDeploy Device Tree(s)Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Buildsystem, Device TreeLowNo

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.

2.8b3 (Release date: 2018-06-27)
ELB-981FixedYocto Project Layer Readmes May Not be Up-to-dateColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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-966FixedLegacy Update Procedure Fails on Colibri T20 256MB With Regular LXDE Demo ImageColibri T20BuildsystemLowNo

Description: Unfortunately, starting with BSP 2.8b2 the regular LXDE based demo image root file system reached a size which does no longer easily fit into 256MB of RAM, therefore, failing the legacy update procedure (it may just hang or even crash but definitely fails updating the root file system).

Workaround: Doing the following before 'run setupdate; run update' helps:
setenv fdt_addr_r 0x01000000

ELB-960FixedBuilding on Ubuntu 18.04 FailsColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Building 2.8b2 and earlier fails on Ubuntu 18.04 LTS.

Workaround: It works on Ubuntu 16.04 LTS.

ELB-926FixedToradex Configuration Block Off by One IssueColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Bootloader, ConfigBlockLowNo

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-925FixedCan Not Install Individual Backport Kernel ModuleColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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-916FixedAdd Atmel mxt touch controller driver support for reset gpioColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Capacitive TouchLowNo

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-906FixedMake Latest OE-Core, Morty Compatible With meta-toradex-bsp-commonColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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 PACKAGES_prepend = "\ ${PN}-sd8887 \ " from meta-toradex-bsp-common/recipes-kernel/linux-firmware/linux-firmware_%.bbappend

ELB-904New FeatureAdd Configuration File(s) And mxt-app to Allow Loading It For PCAP Touch ScreensColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Capacitive TouchLowNo

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

2.8b2 (Release date: 2018-03-31)
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-909FixedFix scrot Recipe Source/MirrorColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

ELB-899FixedRegression: Automounting Fails With systemd udev RulesColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Buildsystem, SATA, SDIO/SD/MMC, USBLowNo

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-897FixedBitbaking stress Reports Checksum MismatchColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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-877FixedImage Viewer gpicview is no Longer in Demo ImageColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Buildsystem, GraphicsLowNo

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-819New FeatureProvide LXQt Demo Image Similar to LXDE OneColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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-742FixedBuild Failure When Building Image the Next Day Without ChangesColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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-565New FeatureImprove angstrom-qt5-x11-Image by Using xinit to Start XColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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

2.8b1 (Release date: 2017-12-29)

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-826FixedBoth fchdir() And fstat() Fail With EBADF When File Was Previously Opened with O_PATH Flag on T20/T30Colibri T20, Colibri T30, Apalis T30KernelLowNo

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-820New FeatureEnable Message when User Program CrashesColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30KernelLowNo

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-778New FeatureUpdate to OpenEmbedded Rocko and Yocto Project 2.4Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Add a -v parameter to fw_printenv/fw_setenv which outputs the U-Boot source version information.

ELB-636New FeatureAllow for Easier OpenEmbedded Machine ConfigurationColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

Description: Allow for easier OpenEmbedded machine configuration by our customers.

2.7b4 (Release date: 2017-10-05)
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-736FixedDefine Standard Rootfs Mount Behaviour and OptionsColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Bootloader, FlashMediumNo

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-719FixedPower I2C Bus Communication Speed Should be Reduced to 100 KHzColibri T20, Colibri T30, Apalis T30I2C, Power ManagementLowNo

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-705New FeatureSupport Forcing 'cfgblock create' to Overwrite Existing Config BlockColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BootloaderLowNo

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-699FixedEject Feature for Mass Storage MissingColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30SATA, SDIO/SD/MMC, USBLowNo

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-693FixedUnify Behaviour When Config Block Is MissingColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BootloaderLowNo

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-681New FeatureAdd support for LM816 (RTL8188EU)Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Wi-FiLowNo

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-639FixedPotential Systemd Hang on First BootColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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-635FixedModule May Draw More PowerColibri T20Graphics, KernelLowNo

Description: Colibri T20 modules may draw more power be it during regular operation or in suspend.

Workaround: This issue is related to the 'Module May Hang During Boot if HDMI is not Connected' one whose fix can be found on the tegra-next branch of our linux-toradex Linux kernel repository: http://git.toradex.com/cgit/linux-toradex.git/log/?h=tegra-next

ELB-627FixedHDMI Hot-Plugging Fails Configuring Desktop OutputApalis TK1, Colibri T20, Colibri T30, Apalis T30HDMILowNo

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.

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-586New FeatureRemove Unneeded RDEPENDS From Our RecipesColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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-521New FeatureSoC Unique NumberColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Miscellaneous PeripheralsLowNo

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-541FixedAdjust X22 EvalLoc in GPIO Tool (formerly GPIOConfig) to Latest Colibri Evaluation Board V3.2 PinoutColibri iMX6, Colibri T20, Colibri T30GPIOLowNo

Description: The X22 pinout changed on the latest Colibri Evaluation Board V3.2. Showing the latest information is desirable as that is what a customer gets shipped if ordered now.

ELB-517New FeatureConfigure IPv6-in-IPv4 Tunnel (SIT Driver) as ModuleColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Colibri T20, Colibri T30, Apalis T30EthernetLowNo

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-506New FeatureUpdate U-Boot for all Modules to be Based on U-Boot 2016.11 ReleaseColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BootloaderLowNo

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-505New FeatureOpenEmbedded: Update to the Morty ReleaseColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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-440FixedDHCP Server on USB RNDIS Announces Module as RouterColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30USBLowNo

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-434FixedOE Build on Distro with GCC 6 Host ToolchainColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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-420FixedMove to GTK+ 3 in Demo ImageColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Buildsystem, GraphicsLowNo

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-417New FeatureDistro Boot IntegrationColibri iMX7, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Bootloader, SDIO/SD/MMC, USBLowNo

Description: Further U-Boot distro boot integration would allow booting off regular ARM distro's SD cards or USB mass storage devices aka memory sticks.

ELB-380New FeatureConsider Using Udisks2Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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.

V2.6.1 Beta 1 (Release date: 2016-10-01)
ELB-443New FeatureGCC-6 Usable as the CrosstoolchainApalis TK1, Colibri T20, Colibri T30, Apalis T30KernelLowNo

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-424New FeatureUnify and Document the Use of fdt_fixupColibri iMX7, Apalis iMX6, Colibri iMX6, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BootloaderLowNo

Description: The PMIC RTC does not meet the expected accuracy.

Workaround: If possible use the external RTC provided by the carrier board.

ELB-308FixedStuck in U-Boot SPL upon Watchdog ResetColibri T20Bootloader, Power Management, WatchdogLowNo

Description: Upon boot after a watchdog reset the U-Boot boot loader gets stuck in SPL. Only a full power-cycle will recover the system.

Workaround: Our stable Embedded Linux BSP V2.3 from 20150320 does not exhibit this issue.

ELB-296FixedSoftware Reboot Lock-upColibri T20KernelLowNo

Description: Rarely after about 500 software reboot cycles the module locks up during boot.

Workaround: Just power-cycle again.

V2.4 Beta 1 (Release date: 2015-05-18)
ELB-152FixedDifferent Mountpoint Names when Mounted at Boot vs. Mounted at Runtime / with DiskutilityApalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Colibri T20, Colibri T30, Apalis T30SATA, SDIO/SD/MMC, USBLowNo

Description: Mountpoint names are different when mounted at boot vs. mounted at runtime / with diskutility.

Description: Sync U-Boot DTS with the Linux mainline

ELB-1183Known IssueBoot Error "commit machine-id"Colibri T20, Colibri T30, Apalis T30KernelLowNo

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-1157Known IssueSoftware Reset Doesn't Always Work CorrectlyColibri T20Bootloader, KernelLowNo

Description: Some modules sometimes do not boot after a software reset.

Workaround: Triggering a reset via PMIC reliably initiates a hard reset e.g. doing the following from within U-Boot:
i2c dev 0
i2c mw 0x34 0x14 1 0x01

ELB-1120Feature RequestAdd Modules Parameter to MWiFiex Driver For Single Antenna OperationApalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30, Apalis iMX8Wi-FiLowNo

Description: For single antenna set single_rf=0x01

ELB-1116Feature RequestT20/T30 Internal Video DAC OutputColibri T20, Colibri T30, Apalis T30Graphics, VGALowNo

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-1111Known IssueUART Input OverrunColibri T20, Colibri T30, Apalis T30UARTLowNo

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-1025Known IssueNative compilation using arm-angstrom-linux-gnueabi-gcc not working with GCC 7.2 and aboveColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Apalis T30BuildsystemLowNo

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-1003Known IssueHDMI HDA Audio IssuesColibri T20, Colibri T30, Apalis T30Digital Audio, HDMILowNo

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-1002Known IssueU-Boot Splash Screen Not WorkingApalis TK1, Colibri T20, Colibri T30, Apalis T30BootloaderLowNo

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-978Known IssueLegacy Update Procedure May Fail With Bigger ImagesColibri iMX7, Colibri VF50, Colibri T20FlashMediumNo

Description: On NAND flash based modules like the Colibri T20, the legacy update procedure depends on first loading the entire root file system image into RAM. If your custom image is significantly larger than our regular demo images it may no longer easily fit into 256MB of RAM, therefore, failing the legacy update procedure (it may just hang or even crash but definitely fails to update the root file system).

Workaround: Doing the following before 'run setupdate; run update' may help to a certain extend:
setenv fdt_addr_r 0x01000000
However, even bigger images may still fail requiring a different flashing strategy altogether (e.g. initially booting from an initrd or via NFS subsequently updating the root file system from within Linux on-the-fly.

ELB-976Known IssueYear 2038 IssueColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Kernel, Miscellaneous Peripherals, RTCLowNo

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-975Known IssueLXDE, Moved Desktop Icons are not Redrawn AutomaticallyColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30RGBLowNo

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.

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-880Feature RequestAdd a Qt5 Based Browser to the LXQt recipeColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30, Apalis iMX8Browser, BuildsystemLowNo

ELB-767Known IssueLegacy Ubuntu 12.04 Not Compatible With Our Update ScriptColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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-757Known Issue/etc/profile Not Properly Sourced Upon Graphical LoginColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30GraphicsLowNo

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-702Known IssueNTSC Decoding With ACA (ADV7280 Resp. ADV7280-M)Apalis TK1, Colibri T20, Colibri T30, Apalis T30Camera Parallel Interface, CSILowNo

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-692Known IssueUSB Memory Sticks Not Working Reliably in U-BootColibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30, Apalis iMX8Bootloader, USBLowNo

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-674Known IssueSometimes the RTC Driver Recovers Invalid Date/Time from the External RTCColibri T20, Colibri T30, Apalis T30RTCLowNo

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-638Known IssueU-Boot: Certain USB Memory Sticks May Not Work Reliably Behind a USB HubColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BootloaderLowNo

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-602Known IssueColibri T30 May Freeze on Concurrent SD Card and Multiple USB Devices Stress TestingColibri T20, Colibri T30, Apalis T30SDIO/SD/MMC, USBLowNo

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-571Known IssueMemory Corruption with ext4 FilesystemColibri T20, Colibri T30, Apalis T30Flash, Kernel, SATA, SDIO/SD/MMC, USBMediumNo

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-530Known IssueIrDA not ImplementedColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30IrDALowNo

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-496Known IssueTemperature Test on Colibri T20 Uncovered UBI Error When Using bonnie++ With Latest ImageColibri T20FlashMediumNo

Description: Temperature test on Colibri T20 uncovered UBI error when using bonnie++ with latest image.

Workaround: Use stable BSP V2.3 based on YAFFS2.

ELB-463Known IssueSPDIF not WorkingColibri T20, Colibri T30, Apalis T30Digital AudioLowNo

Description: SPDIF is not working in the V2.6 beta 2 release. This is a regression against older releases.

ELB-452Known IssueUSB OTG on Aster, Orchid, Viola Need USB_P_EN# for Host RoleColibri iMX7, Colibri iMX6, Colibri VF50, Colibri VF61, Colibri T20, Colibri T30USBLowNo

Description: On Aster, Orchid and Viola the USB power enable pin (SODIMM 129) is used for both USB ports USBC and USBH. For all modules but the Colibri iMX7S the Linux kernel controls the USB Power Enable only from the USBH port driver. Thus USBC will be non functional if used as a USB Host when the USBH port is disabled in the kernel (i.e. in the device tree for newer or in the platform data for older kernels). Note that on the Evaluation Board and on Iris the USB Power gets enabled when a USB OTG kabel gets connected.

Workaround: Do not disable the USBH port or change the kernel in a way that the USB Power Enable is controlled by the USBC port as well.

ELB-407Known IssueBusybox and UTF-8 Chars in FilenamesColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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-338Feature RequestLinux Kernel Splash Screen Doesn't Work on HDMI OutputApalis iMX6, Colibri iMX6, Apalis TK1, Colibri T20, Colibri T30, Apalis T30HDMILowNo

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-313Known IssueIncompatibility Between L4T Linux Kernel and iproute2-ss140804Colibri T20, Colibri T30, Apalis T30CANLowNo

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-298Known IssueAudio Capture Stereo IssueColibri T20Analog AudioLowNo

Description: Capturing stereo audio inhibits audio fragments being swapped left/right at times.

Workaround: Use mono capture for now.

ELB-262Feature RequestXinput-Calibrator May Fail When Axis Are SwappedColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Resistive TouchLowNo

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"
EndSection
