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.

Description: Enable HMP support on Verdin iMX8M Mini with dedicated dtb overlay on Upstream Distro.

ELB-5294FixedPotential DRAM DDR Memory Data Lost Above 85ºCVerdin iMX8M MiniBootloader, RAMLowNo

Description: As per NXP errata ERR050805 (https://www.nxp.com/docs/en/errata/IMX8MM_0N87W.pdf), DRAM Controller automatic de-rating logic may not work when the LPDDR4 memory temperature is above 85ºC at initialization. The DDR Controller will therefore not automatically adjust the memory refresh rate or de-rate memory timings based on the LPDDR4 memory temperature. This may cause the controller incorrectly setting the refresh period, potentially cause the LPDDR4 memory losing data contents and lead to possible data integrity issues above 85ºC.

ELB-4481Known IssueWrong Playback Sample Rate on Analog AudioVerdin iMX8M Mini, Verdin iMX8M PlusAnalog AudioLowNo

Description: Audio is played with the wrong sample rate (44100 vs 48000 Hz) on Verdin Development Board, a 6.5 seconds audio file plays in about 6 seconds (8% faster)

Workaround: Use 48kHz sample rate or set `simple-audio-card,mclk-fs = <256>;` in sound_card dts node.

ELB-4268Known IssueUSB Host Port Only Working if Plugged During BootVerdin iMX8M MiniUSBLowNo

Description: Hot-plugging USB devices on the USB host port USB_2 does not work on a custom carrier board without a USB hub in-between. Note that current Toradex carrier boards (Dahlia and the Verdin Development Board) do have such a USB hub and therefore do NOT exhibit this issue as the USB hub itself is handling the hot-plugging. This issue is related to USB runtime power-management.

Workaround: Add `power-domains = <&usb_otg2_pd>;` property to `&usbphynop2` node in the device tree.

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 InstallerApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusBuildsystemNo

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.

ELB-3475New FeatureChange recipes to fetch from https instead of gitApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusBuildsystemNo

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-3340FixedAfter Waking up From Suspend Mode, Ethernet Is DisabledVerdin iMX8M MiniEthernetLowNo

Description: Ethernet is disabled when waking up after a suspend.

ELB-3337New FeatureConsistent /boot Mounting if Booting From SD Card or USB Memory StickApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusFlashNo

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-3327New FeatureUpdate Userspace to NXP L5.4.70-2.3.0 ReleaseApalis iMX6, Apalis iMX8, Apalis iMX8X, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusBuildsystemNo

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-2890New FeatureBroken eMMC Command Queuing FeatureVerdin iMX8M MiniFlash, SDIO/SD/MMCNo

Description: The eMMC command queuing feature is broken in NXP BSP L5.4.70_2.3.0. Therefore, we had to disable it to avoid any corruption.

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 InstanceApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusBootloader, BuildsystemNo

Description: Make sure the boot partition on eMMC-based modules is mounted consistently across all modules to /boot.

ELB-3226New FeatureMake RTC Backup FunctionalVerdin iMX8M MiniRTCNo

Description: The RTC on the Verdin iMX8 needs additional configuration to keep running on the backup battery voltage on power outage. It will be configured as the default.

Workaround: There are no workarounds, you must wait until this is implemented. Please contact us if you need this feature with urgency.

ELB-3195FixedDrop ptest From DISTRO_FEATURESApalis iMX6, Apalis iMX8, Apalis iMX8X, Apalis TK1, Colibri iMX6, Colibri iMX6ULL, Colibri iMX7, Colibri iMX8X, Verdin iMX8M Mini, Verdin iMX8M PlusBuildsystemLowNo

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-3003FixedMwifiex: Invalid Sched_Scan ParametersApalis iMX8, Apalis iMX8X, Colibri iMX6ULL, Colibri iMX8X, Verdin iMX8M MiniWi-FiLowNo

Description: When using the on-module Wi-Fi "Invalid Sched_scan" message appears. This error message has no meaning in our use-case so we removed it.
