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 in 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 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.

5.2.0 (Release date: 2021-04-08)
Embedded Linux BSP Q1 2021 Quarterly Release. Learn more on https://www.toradex.com/news/bsp-layers-reference-images-yocto-project-5-2-0-quarterly
ELB-3499New FeatureApalis iMX8 Images Additionally Contain Apalis iMX8X OverlaysVerdin iMX8M Plus, Verdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1, Apalis iMX8Device TreeLowNo

Description: An image for Apalis iMX8 contains in addition to the ones specific to Apalis iMX8 the specific ones for Apalis iM8X. While this does not hurt it might be confusing.

Workaround: -

ELB-3485New FeatureAdd EULA License Accept Window When Installing an Image Using the Toradex Easy InstallerVerdin iMX8M Plus, Verdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1, Apalis iMX8BuildsystemLowNo

Description: Show EULA license on tdx-reference images that has to be accepted when installed with the Toradex Easy Installer. Note that our tdx-reference images can no longer be installed unattended using the Toradex Easy Installer.

Workaround: Remove the "license" line in the image.json file.

ELB-3475New FeatureChange recipes to fetch from https instead of gitVerdin iMX8M Plus, Verdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1, Apalis iMX8BuildsystemLowNo

Description: Change OpenEmbedded recipes from Toradex to fetch from https instead of git where possible.
In an approach to make it more user-friendly, especially for big company customers that do not allow git-protocol in their networks we decided to use https as a fetching source.
We are aware that we cannot do this for each and every layer but at least for ours we decided to switch from git to https.

ELB-3337New FeatureConsistent /boot Mounting if Booting From SD Card or USB Memory StickVerdin iMX8M Plus, Verdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1, Apalis iMX8FlashLowNo

Description: Due to the class "classes/image_type_tezi.bbclass" in "meta-toradex-bsp-common" setting the label to all upper-case "BOOT", and WIC images using all lower-case "boot", the /boot mounting may actually not work at all (given that an image got actually installed to eMMC using the Toradex Easy Installer prior to distrobooting from SD card and/or USB memory stick). However, rather than having the eMMC's boot partition mounted to /boot it would make much more sense to mount the resp. boot media's boot partition there.

ELB-3197New FeatureWIC Images do NOT Contain Device Tree OverlaysVerdin iMX8M Plus, Verdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1, Apalis iMX8Device TreeLowNo

Description: WIC images do not contain the device tree overlays. This affects users that boot from the SD card or USB sticks. See Boot From an SD Card / USB Stick / SATA drive for reference.

Workaround: Manually deploy them. See how-to on Deploying a Device Tree Overlay.

ELB-2710New FeatureDrop fdt_fixup and Clean-up DocumentationVerdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1, Apalis iMX8BootloaderLowNo

Description: We dropped support for fdt_fixup in favour of using device tree overlays.

5.1.0 (Release date: 2020-12-30)
Dunfell Q4 2020 Quarterly Release. Learn more on https://www.toradex.com/news/bsp-layers-reference-images-yocto-project-5-1-0-quarterly
ELB-3322New FeatureWIC Images May Fail Mounting /bootVerdin iMX8M Plus, Verdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1, Apalis iMX8FlashLowNo

Description: WIC images fail mounting /boot. Looks like classes/image_type_tezi.bbclass in meta-toradex-bsp-common is setting the label to all upper-case BOOT while WIC images are using all lower-case boot. This is particularly bad on Verdin iMX8M Plus as due to no Toradex Easy Installer being available as of yet we are using WIC images with the bmap tool for production flashing.

ELB-3293New FeatureMake /etc/fw_env.config Unaware of Used Block Device InstanceVerdin iMX8M Plus, Verdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1, Apalis iMX8Bootloader, BuildsystemLowNo

Description: Use unified /dev/apalis-emmc symlinks for fw_env.config so we only need one config for all modules.

ELB-3271New FeatureDocument/Fix Display Interface DefaultsVerdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1, Apalis iMX8Graphics, HDMI, RGBLowNo

Description: Make sure to document on our developer website which display interfaces are used by default.

ELB-3254New FeatureMerge Latest Kernel.org 5.4 LTS Commits (Plus RT Patch Update)Verdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1, Apalis iMX8KernelLowNo

Description: Merge latest kernel.org 5.4 LTS commits: Mainline/upstream branch toradex_5.4.y and downstream NXP branch toradex_5.4-2.1.x-imx both updated to 5.4.77 with optional RT patch 5.4.77-rt43.

ELB-3250New FeatureMount Separate FAT Boot Partition to /bootVerdin iMX8M Plus, Verdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Apalis iMX6, Colibri iMX6, Apalis TK1, Apalis iMX8FlashLowNo

ELB-3035New FeatureDrop defconfigs in OE Meta-DataVerdin iMX8M Plus, Verdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1, Apalis iMX8Buildsystem, KernelLowNo

Description: Use KBUILD_DEFCONFIG in OpenEmbedded to define the defconfig to build the kernel from. Toradex is now using the defconfigs from the kernel-repo instead of providing separate defconfigs in OpenEmbedded. However if you wish to provide your own defconfig in OpenEmbedded you can still do so.

ELB-2975New FeatureDistroboot DHCP Boot Requires New Format of Scripts to Make it FunctionalVerdin iMX8M Plus, Verdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1, Apalis iMX8BootloaderLowNo

Description: Enable Linux kernel support for the CAN SAE J1939 protocol for the vehicle bus recommended practice used for communication and diagnostics among vehicle components.

Workaround: You may manually enable CONFIG_CAN_J1939, re-build and re-deploy the Linux kernel and/or Linux kernel modules.

ELB-2891New FeatureDrop BackportsVerdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1, Apalis iMX8KernelLowNo

Description: With the move to the NXP L5.4.24-2.1.0 BSP we will have all our downstream and mainline/upstream Linux kernels based on 5.4. Using 5.4 based backports with this does not make any sense so drop it.

ELB-2874New FeatureAdd systemd-analyzeVerdin iMX8M Mini, Apalis iMX8X, Colibri iMX8X, Colibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Apalis TK1, Apalis iMX8BuildsystemLowNo

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-1031FixedUSB OTG High Speed Host Not Working CorrectlyApalis TK1USBLowNo

Description: Apalis TK1 running BSP 2.8b3 may experience issues connecting USB 2.0 devices to the OTG USB port.

Workaround: Modify the U-Boot defargs environmental variable from "usb_port_owner_info=3" to "usb_port_owner_info=2" to disable USB 3.0 for stable OTG operation. This is now the default as of BSP 2.8b6.

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-1034FixedDual CAN Operation on Apalis TK1 May Cause CAN to Stop WorkingApalis TK1CANLowNo

Description: In dual CAN operation, Apalis TK1 CAN may stop working, when error or collision happens on one of the busses.

ELB-1024FixedCAN frames with baud rate different then 1Mbps will be treated as invalid between driver probe and interface upApalis TK1CANLowNo

Description: In a period between driver initialisation and interface bring-up, packets send on the bus with baud rate different then 1Mbps will be treated as invalid.

ELB-1017FixedAdjusting Apalis TK1 LVDS Drive Strength SettingsApalis TK1LVDSLowNo

Description: Apalis TK1 LVDS drive strength settings are hard-coded. Idea is to move those to the device tree as well.

Workaround: For now, settings can be changes in drivers/video/tegra/dc/sor.c file. Function tegra_dc_sor_enable_lvds contains writes to NV_SOR_LANE_DRIVE_CURRENT and NV_SOR_LANE4_DRIVE_CURRENT registers. Registers definitions can be found in the "Tegra K1 Reference Manual".

ELB-1014New FeatureAdd support for new [01491101] CSI Camera Module 5MP OV5640 V1.1BApalis iMX6, Apalis TK1, Apalis T30CSILowNo

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-1005FixedApalis TK1 PCIe Gigabit Bring-up Issue in MainlineApalis TK1Ethernet, PCIeLowNo

Description: Forward ported commit 7ad9771527d2 ("apalis-tk1: fix PCIe reset for reliable gigabit Ethernet operation") was never validated. Turns out it does not work and may lead to PCIe gigabit bring-up issues.

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-999FixedFails Poweroff/Shutdown Instead Reboots When Using Mainline LinuxApalis TK1Bootloader, KernelLowNo

Description: The apalis-tk1-mainline machine fails poweroff/shutdown and instead just reboots.

Workaround: The rocko-next branch of meta-toradex-tegra features a patch which disables the AMS AS3722 PMIC's auto power on when AC OK feature otherwise enabled by default and causing a reboot rather than full poweroff.

ELB-991FixedFix SDK libGL.so, Currently it is a Dangling SymlinkApalis TK1BuildsystemLowNo

Description: In a SDK the symlink sysroots/armv7at2hf-neon-angstrom-linux-gnueabi/usr/lib/arm-linux-gnueabihf/tegra/libGL.so currently points to ./arm-linux-gnueabihf/tegra/libGL.so.1 which does not exist.

Workaround: Fix the symlink in the unpacked SDK: ln -fs libGL.so.1 .../sysroots/armv7at2hf-neon-angstrom-linux-gnueabi/usr/lib/arm-linux-gnueabihf/tegra/libGL.so

ELB-988New FeatureUpdate to NVIDIA's latest Linux for Tegra aka L4T R21.7Apalis TK1Buildsystem, KernelLowNo

Description: Update to NVIDIA's latest Linux for Tegra aka L4T R21.7 https://developer.nvidia.com/linux-tegra-r217.

Workaround: The Linux kernel changes are already available on the toradex_tk1_l4t_r21.7-next branch. The rest of the integration is already available in the rocko-next branch of our meta-toradex-tegra repository.

ELB-979FixedOpenCV4Tegra Fails Building Due to Missing DependenciesApalis TK1CSI, GraphicsLowNo

Description: OpenCV4Tegra currently fails to build due to a missing dependency on libpng12.

Workaround: The libpng12 recipe has been re-added to the rocko-next branch of meta-toradex-tegra so OpenCV4Tegra is at least buildable again. However, for full OpenCV4Tegra support, we recommend using NVIDIA's JetPack resp. Linux for Tegra aka L4T as explained in the following article on our developer website:
https://developer.toradex.com/knowledge-base/installing-nvidia-jetpack-with-l4t-on-apalis-tk1

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-943FixedLegacy Update is not Deploying V1.2 Device TreeApalis TK1BuildsystemLowNo

Description: Apalis TK1 legacy update is not deploying the v1.2 devicetree.

Workaround: Use Toradex Easy installer or u-boot ums mode.

ELB-936New FeatureAdd libsoc to Image RecipesColibri iMX7, Colibri iMX6ULL, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1GPIOLowNo

Description: libsoc is a C library to interface with common peripherals found in System on Chips (SoC) through generic Linux Kernel interfaces. As libsoc supports more and more of our modules we add libsoc support to our regular images.

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

Description: Support USB 3.0 SuperSpeed on USBO1.

Workaround: Use USB 3.0 SuperSpeed on USBH4 for now. Alternatively, the mainline Linux kernel already supports USB 3.0 SuperSpeed on USBO1 as well as USBH4. You may also use the latest mainline Linux based demo image Apalis-TK1-Mainline_LXDE-Image as can be found at http://developer.toradex.com/files/toradex-dev/uploads/media/Colibri/Linux/Images/.
Such fix/support may now be found in the 2016.11-toradex-next U-Boot and toradex_tk1_l4t_r21.6-next Linux kernel branches of our git repositories.
Please note that one may not switch back to USB device functionality once USB 3.0 SuperSpeed host functionality has previously been used.

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

Description: We fixed CAN after NVIDIA's recent L4T R21.6 SPI improvements.

ELB-812New FeatureUpdate to NVIDIA's latest Linux for Tegra aka L4T R21.6Apalis TK1Buildsystem, KernelLowNo

Description: Update to NVIDIA's latest Linux for Tegra aka L4T R21.6 https://developer.nvidia.com/linux-tegra-r216.

Workaround: The Linux kernel changes are already available on the toradex_tk1_l4t_r21.6-next branch. The rest of the integration is already available in the morty-next branch of our meta-toradex-tegra repository.

ELB-797New FeatureCreate NVIDIA JetPack Toradex Easy Installer ImageApalis TK1BuildsystemLowNo

Description: It would be very convenient to just be able to install NVIDIA's JetPack via Toradex Easy Installer once available for Apalis TK1.

Workaround: For now just stick to the rather cumbersome manual installation procedure: http://developer.toradex.com/knowledge-base/installing-nvidia-jetpack-with-l4t-on-apalis-tk1

ELB-795FixedDDC/EDID Detection Failing on IxoraApalis TK1Graphics, HDMI, I2CLowNo

Description: DDC/EDID detection was failing using Apalis TK1 V1.2A with 2.7b4 on Ixora.

ELB-780FixedGPIO Tool: Fix Pinmuxing for Apalis TK1 V1.2 HardwareApalis TK1GPIOLowNo

Description: As we juggled around some of the pins the GPIO Tool also needs updating.

ELB-751New FeatureAdd Support for Apalis TK1 2GB V1.2AApalis TK1Bootloader, Buildsystem, KernelLowNo

Description: Add support for Apalis TK1 2GB V1.2A.

ELB-580FixedImprove CSI Camera Module 5MP OV5640 SupportApalis TK1CSILowNo

Description: Camera support has been greatly improved by an update to the OV5640 driver from our camera partner Antmicro as well as NVIDIA's latest L4T R21.6 update.

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-774New FeatureSupport Toradex Easy Installer Package Format for Apalis TK1 ModulesApalis TK1BuildsystemLowNo

Description: Provide the Apalis TK1 BSPs also in a Toradex Easy Installer package.

ELB-758FixedNo PWM Functionality on Apalis PWM3 PinApalis TK1PWMLowNo

Description: While the Apalis PWM3 pin is shared with the Apalis BKL1_PWM pin currently the former does not have the PWM pin muxing activated. Note that exporting PWM3 for raw sysfs access will therefore fail and one has to revert to using the pwm backlight.

Workaround: Change resp. pin muxing in the device tree. You may find a patch on our toradex_tk1_l4t_r21.5-next branch.

ELB-749FixedConfig Block Check During Update May Fail Depending on Hardware Area Boot Partition SizeColibri iMX7, Apalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30Bootloader, BuildsystemLowNo

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-748FixedEnable Second CAN ChannelApalis TK1CANLowNo

Description: Target is to achieve >2k msg/s on both CAN channels.

ELB-740FixedPotential Gigabit Ethernet resp. PCIe InstabilityApalis TK1Bootloader, Ethernet, Kernel, PCIeLowNo

Description: So far in U-Boot we violated the PCIe reset timing specification and in Linux we did not do anything about doing the PCIe reset unisono with the separately switchable voltage rail of the gigabit Ethernet chip.

Workaround: A solution to the U-Boot side of things may be found on our -next branch now.

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-725Fixed'run update' Fails if the Rootfs is Exactly a Multiple of 64MApalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30BootloaderLowNo

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-716FixedInclude Gstreamer 0.10Apalis TK1MultimediaLowNo

Description: Unfortunately our current Angstrom/OpenEmbedded/Yocto BSP exclusively uses gstreamer 1.0 which we learned from multiple sources is not really production ready for TK1. We may consider switching to or at least including gstreamer 0.10 in the future as well.

Workaround: Use JetPack for now which allows installing both gstreamer 0.10 as well as 1.0. http://developer.toradex.com/knowledge-base/installing-nvidia-jetpack-with-l4t-on-apalis-tk1

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-704New FeatureUse Ext4 File System by DefaultApalis iMX6, Colibri iMX6, Apalis TK1FlashLowNo

Description: Use the ext4 file system by default.

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/16464/image-27b4-fails-to-mount-rootfs.html

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: Add the driver for RTL8188EU which is e.g. used in LM816 to our standard images.

ELB-675FixedSometimes the RTC Driver Recovers Invalid Date/Time from the External RTCApalis TK1RTCLowNo

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-555New FeatureUpdate/Include Bluetooth/Wi-Fi Kernel Modules (aka Backports)Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30Bluetooth, Buildsystem, Kernel, Wi-FiLowNo

Description: Include multiple Bluetooth and Wi-Fi kernel modules in our BSP demo image release packages.

Workaround: You may find our backports based on Linux kernel 4.11 here: http://git.toradex.com/cgit/backports-toradex.git/log/?h=toradex-4.11

ELB-427New FeatureImplement CAN FunctionalityApalis TK1CANLowNo

Description: Add support for the CAN feature of the Apalis TK1 module.

Description: Bring-up digital audio interface DAP1.

ELB-701New FeatureSnappy Ubuntu Core Yocto Project Layer IntegrationApalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30BuildsystemLowNo

Description: There is now an experimental meta-snappy which allows regular Yocto project BSPs to support running Ubuntu Core snaps. Integrate this in our regular demo images.

ELB-661Fixedsdboot Using ext4 Rootfs FailsApalis TK1BootloaderLowNo

Description: Trying to sdboot from an ext4 rootfs fails due to us defaulting to ext3. While the downstream T20/T30 L4T kernel has issues with ext4 later TK1 L4T should work just fine with it.

Workaround: Just change the sdargs to ext4 as follows: setenv sdargs 'ip=off root=/dev/mmcblk1p2 rw rootfstype=ext4 rootwait'

ELB-657FixedImages: Configure systemd Without ACL SupportColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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-599New FeatureUpdate to Yocto Project Jethro Release 2.0.3Colibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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.

2.7b2 (Release date: 2017-04-10)
ELB-1476New FeatureTest Low-Power/Suspend ModesApalis TK1Power ManagementLowNo

Description: Test low-power/suspend modes.

ELB-652FixedGPIO Tool: Fix Pinmuxing for NANDF_D4 (Apalis iMX6) and Apalis GPIOs (Apalis TK1)Apalis iMX6, Apalis TK1GPIOLowNo

Description: Apalis iMX6: The gpio-tool can not read or change the current pinmuxing of the NANDF_DATA4 pin but rather the SD4_DAT6 pin got changed instead. Apalis TK1: Some of the Apalis GPIOs were not accessible with the gpio-tool.

Workaround: Don't use the gpio-tool for pin NANDF_DATA4 on Apalis iMX6.

ELB-650New FeatureNew Versioning SchemeColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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-628New FeatureDeploy Mmc-UtilsApalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30Buildsystem, Flash, SDIO/SD/MMCLowNo

Description: The mmc-utils allow e.g. inspecting the current health and life time estimation of the on-module eMMC.

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.

ELB-618FixedCPU & GPU Thermal Throttling Not WorkingApalis TK1CPU, Device Tree, Graphics, Kernel, Power Management, Temperature SensorLowNo

Description: CPU and GPU thermal throttling is not working which can be seen from /sys/kernel/debug/tegra_throttle/ being empty.

Workaround: Find the fix on our -next branch.

ELB-601FixedUpdate Meta-Angstrom to Latest Resulting in Using Linaro GCC 6 CompilerColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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: 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-477FixedSDIO Lock-upApalis TK1Kernel, SDIO/SD/MMC, Wi-FiLowNo

Description: Testing various SDIO based Wi-Fi solutions we observed it to completely lock-up the system.

Workaround: Find the following commit fixing this: http://git.toradex.com/cgit/linux-toradex.git/commit/?h=toradex_tk1_l4t_r21.5&id=20e255fde2d32d8bccd9e589fad4a2f663fcfb3a

ELB-447FixedFramebuffer Boot Configuration Integration MissingApalis TK1LVDSLowNo

Description: The frame buffer boot configuration integration via kernel command line is still missing.

Workaround: The LVDS configuration is currently hard-coded here: http://git.toradex.com/cgit/linux-toradex.git/tree/arch/arm/mach-tegra/panel-c-lvds-1366-14.c?h=toradex_tk1_l4t_r21.5#n322

ELB-149New FeatureConfigure Optimised MMC Read-AheadColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20Flash, SDIO/SD/MMCLowNo

Description: Configure optimised MMC read-ahead.

Workaround: Manually set /sys/block/mmcblk0/queue/read_ahead_kb.

V2.7 Beta 1 (Release date: 2017-01-13)
Known Issue for Colibri VF61: U-Boot 2016.11 Missing m4boot Command.
ELB-597FixedSysV Initscript Interference at Times Causing Networking Subsystem not to StartColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30BuildsystemLowNo

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-556New FeatureLinux-ptp in BSPColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Apalis T30Buildsystem, EthernetLowNo

Description: Include linuxptp in BSP image

ELB-519New FeaturePort GPIO Tool to Apalis TK1Apalis TK1GPIOLowNo

Description: The gpio-tool will allow to override pin muxing functionality and test GPIO input/output functionality.

ELB-515New FeatureSupport I2C RTCApalis TK1I2C, RTCLowNo

Description: Support I2C RTC.

Workaround: Use PMIC integrated RTC for now. Alternatively the mainline Linux kernel already supports the board-level I2C RTC.

ELB-508FixedUpdate Scripts Limits rootfs Size to around 5GB when using TFTPApalis iMX6, Apalis TK1, Colibri T30, Apalis T30FlashMediumNo

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-507FixedUpdate Scripts Limits rootfs Size to 4GBApalis iMX6, Colibri iMX6, Apalis TK1, Colibri T30, Apalis T30FlashMediumNo

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-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: Update our layers and the OE setup to support and use the morty release aka. Yocto Project 2.2.

ELB-497FixedeMMC Partition Limited to 8GBApalis TK1FlashMediumNo

Description: Currently our update.sh script limits the partition size to around 8GB by default so even after our automatic resizing only 8GB of the 16GB of available eMMC space can be used.

Workaround: Manually modify the EMMC_SIZE calculation for apalis-tk1 in our update.sh script. Our upcoming Toradex Easy Installer will no longer suffer from this limitation.

ELB-492FixedSSH X11 Forwarding is Disabled by DefaultColibri iMX7, Apalis iMX6, Colibri iMX6, Colibri VF50, Colibri VF61, Apalis TK1, Colibri T20, Colibri T30, Apalis T30EthernetLowNo

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-486New FeatureSupport Touchscreen and ADC on K20 MCUApalis TK1Resistive TouchLowNo

Description: Integrate K20 MCU based touchscreen support connected to TK1 via SPI.

ELB-481New FeatureSupport Basic GPIO Feature on K20 MCUApalis TK1GPIOLowNo

Description: Add support to use signals from the K20 companion MCU connected to the MXM connector as GPIOs. Basic support will be non-interrupt safe (may sleep) and the latency will be similar to regular SPI GPIO expanders.

ELB-460New FeatureAdd option to completely erase K20 flashApalis TK1FlashLowNo

Description: Documented here: http://developer.toradex.com/knowledge-base/using-k20-companion-mcu-on-apalis-tk1#Erase_Chip_Without_Reprogramming

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 2 (Release date: 2016-11-22)
This is a release for Apalis TK1 2GB V1.1A only. The January 2017 release supporting all platforms (iMX6, iMX7, VFxx, T20, T30, TK1) will follow later as V2.7 Beta 1.
ELB-1466New FeatureBring-up eDPApalis TK1Bootloader, eDP, Graphics, KernelLowNo

Description: Bring-up optional eDP.

Workaround: http://git.toradex.com/cgit/linux-toradex.git/commit/?h=toradex_tk1_l4t_r21.5&id=1e2e1af03b1ca26b1659fa45a49a039946a0d14f

ELB-1464New FeatureBring-up CSI-2 Camera InterfacesApalis TK1CSILowNo

Description: Bring-up type specific CSI-2 camera interfaces.

Workaround: http://git.toradex.com/cgit/linux-toradex.git/commit/?h=toradex_tk1_l4t_r21.5&id=4311e45350ad9199a62e5f37b211cee7de4dfb19

ELB-570FixedPCIe Clock and Reset May not Conform to SpecificationApalis TK1PCIeLowNo

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.

Workaround: http://git.toradex.com/cgit/linux-toradex.git/commit/?h=toradex_tk1_l4t_r21.5&id=3e2259b04c2e2c029f742e9dda06a3a2739977d4

ELB-569FixedUpdate Source MirrorApalis TK1BuildsystemLowNo

Description: As that whole source mirror stuff has been introduced rather haphazardly whoever did that also failed maintaining/updating it since V2.5 e.g. http://sources.toradex.com/V2.5/. The wohle process around this is currently unclear.

Workaround: http://git.toradex.com/cgit/meta-toradex-demos.git/commit/?h=jethro&id=a6c6fa422e9cf9586e0eb8aba40e0460513edf58

ELB-568New FeatureConfigure IPv6-in-IPv4 Tunnel (SIT Driver) as ModuleApalis TK1EthernetLowNo

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.

Workaround: http://git.toradex.com/cgit/linux-toradex.git/commit/?h=toradex_tk1_l4t_r21.5&id=1cb425d3e668e3d2b77872d5440fffd87ac9cf21

Workaround: You may use either NVIDIA's L4T directly or at least specific Gstreamer plug-ins therof: http://developer.toradex.com/knowledge-base/installing-nvidia-jetpack-with-l4t-on-apalis-tk1

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-432FixedHigh CPU Usage if no HDMI Screen ConnectedApalis TK1Graphics, HDMI, LVDSLowNo

Description: If no HDMI screen is connected pcmanfm will consume 100% CPU.

Workaround: Removing the '/usr/bin/xrandr --output LVDS-0 --off' line from /etc/xdg/lxsession/LXDE/autostart works around this issue.

Description: The kernel is not stable, sometime kernel `BUG at mm/page_alloc.c` is reported at runtime.

ELB-2876Known IssueApalis TK1 V1.2A.003 with Micron eMMC may experience Timeout Errors due to Non-Conformant RPMB AccessesApalis TK1FlashLowNo

Description: Many eMMC devices have a special partition called RPMB (replay protected memory block). Any access to this partition is protected by a OTP key (our modules are shipped with no key, customer can upload one if they choose to use this partition). Access to this partition can only be done using special commands. Our BSP images provide a utility (mmc-utils-cos) which handles read/write/fuse operations for the RPMB. However, due to the way Linux operates we also need to create a device node in devfs. This creates a special file called /dev/mmcblk0rpmb. Since this is a valid device file it may be opened/read/written by any OS utility and such calls will be translated into requests to the eMMC chip. Unfortunately, those would be invalid eMMC requests. And here is where the difference between Micron and Toshiba eMMC parts shows. Toshiba parts answer invalid data reads with zeros while Micron parts ignore them triggering the kernel timeout mechanism. Since the request is invalid both behaviours may be considered valid. However, modules with Micron eMMC parts may experience lengthy delays due to such timeout processing. When accessed correctly (via the mmc utility) the RPMB works correctly in exactly the same way on both vendor's eMMC parts.

Workaround: Applying the following patch avoids experiencing lengthy delays due to such timeout processing: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4e93b9a6abc0d028daf3c8a00cb77b679d8a4df4

Description: UHS-I modes must be set in the device tree, to make the feature work consistently.

ELB-1161Known IssueSpurious Errors Shown During Legacy Update ProcedureApalis TK1, Colibri T30, Apalis T30BootloaderLowNo

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-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

ELB-990Known IssuePaths in a SDK's qmake Project Include Files are not RelocatedApalis TK1BuildsystemLowNo

Description: If one builds an SDK for Qt5 one gets qmake project include files (*.pri) which contain paths valid for the build host used to compile the SDK rather than paths relocated to where one extracted the SDK to.

Workaround: Fix the paths, e.g. have a look at this community thread: https://www.toradex.com/community/questions/24918/strange-paths-when-installing-angstrom-sdk-for-teg.html

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

Workaround: Updating to a later Wi-Fi backports may help but only marginally.

ELB-851Known IssueRESET_MOCI is Kept in Reset Until Linux Probes PCIe DriverApalis iMX6, Apalis TK1Bootloader, RGB, USBLowNo

Description: U-Boot does not de-assert the RESET_MOCI signal. RESET_MOCI needs to be pulled during PCIe driver initialization sequence. In order to not reset again during Linux boot we do not de-assert RESET_MOCI in the bootloader. Due to this all components on the carrier board connected to RESET_MOCI are kept in their reset state too. On the Evaluation Board that is notably the USB Hub and a display connected to the Unified Interface Display Connector.

Workaround: One may release RESET_MOCI in the bootloader code if needed. During Kernel boot RESET_MOCI will be asserted again for 100ms during PCIe initialization.

ELB-845Known IssueDisconnecting MIPI CSI-2 Camera May Lead to System FreezeApalis TK1CSILowNo

Description: Disconnecting MIPI CSI-2 camera may lead to system freeze.

Workaround: Make sure your camera sensor provides a continuous data stream or stop the capturing first and then allow unplugging.

ELB-825Known IssueExternal HDA Audio Codec not AvailableApalis TK1Digital AudioLowNo

Description: HDA is currently not supported on the digital audio interface DAP1. Therefore the Realtek ALC898 HD audio codec as assembled on the Apalis Evaluation Board won't work.

Workaround: You may use any Linux supported I2S codec like e.g. the SGTL5000 from NXP (formerly Freescale). Please note that custom software adoptions will be required.

ELB-803Known IssueIncrease Resistive Touch Panel Calibration ToleranceApalis TK1Resistive TouchLowNo

Description: Especially on Apalis TK1 where we use full 12-bit capable ADCs the default 15 pixel tolerance is way too small causing frequent misclicks.

Workaround: You may increase the misclick tolerance as follows: sed -i 's/\(BINARY=\"xinput_calibrator\)/\1 --misclick 100/' /usr/bin/xinput_calibrator_once.sh

ELB-801Known IssueFailing I2C Transactions May Freeze Apalis TK1Apalis TK1I2CLowNo

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-747Known IssueApalis TK1 Linux Kernel Fails to Boot With pci=nomsi Command-Line OptionApalis TK1PCIeLowNo

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-676Feature RequestBackport Mainline SGTL5000 Commits Into Apalis TK1 BranchApalis TK1Analog AudioLowNo

Description: Mainline has a number of patches for the SGTL5000 Audio Codec driver, among them the possibility to have multiple instances of the driver running. Test if they can easily be backported into the Apalis TK1 branch.

ELB-655Known IssueeDP Link Training IssueApalis TK1eDP, GraphicsLowNo

Description: Depending on the specific bridge chip or panel used the eDP link training may fail.

Workaround: As the driver fails to adjust the pre-emphasis during link training one can hack the driver to start with a higher initial pre-emphasis value. A possible way to achieve this may be found documented at https://developer.toradex.com/knowledge-base/display-output-resolution-and-timings-linux#Apalis_TK1_eDP_Output

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-624Known IssueHDMI Hot-Plugging May FailApalis TK1Graphics, HDMI, I2C, KernelLowNo

Description: While HDMI hot-plugging works just fine on the Apalis Evaluation board it currently fails with EDID errors on Ixora. It's related to a voltage level incompatibility on Ixora with Apalis TK1 modules.

ELB-575Known IssueLX Panel, CPU Usage Monitor & Confusing Display Due to Dynamic Full ScaleApalis TK1, Colibri T30, Apalis T30CPULowNo

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-554Known IssueExar PCIe UART driver does not work on Apalis T30Apalis TK1, Apalis T30PCIe, UARTLowNo

Description: Exar PCIe UART driver backport (or official Exar driver) does not work on Apalis T30

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-526Feature RequestSGTL5000 Audio Multi Instance Codec DriverApalis TK1, Colibri T30, Apalis T30Analog AudioLowNo

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-510Known IssueGstreamer Video Playback Segmentation FaultApalis TK1Video CodecsLowNo

Description: While gstreamer video playback works fine it segmentation faults at the very end as follows: Caught SIGSEGV exec gdb failed: No such file or directory Spinning. Please run 'gdb gst-launch-1.0 889' to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core.

Workaround: Just Ctrl-C the gstreamer process as indicated.

ELB-487Feature RequestImplementing Linux Serial Driver using K20 UARTsApalis TK1UARTLowNo

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-290Known IssuePCIe GEN2 not Working on Apalis Evaluation BoardApalis iMX6, Apalis TK1PCIeLowNo

Workaround: The mini-PCIe slot on Ixora is known to work also at GEN2 speeds.

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
