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.

ELB-1382Known IssueUHS-I SD Cards May Fail Due to NXP PMIC Errata ER021: VSELECT incorrect set pointApalis iMX8SDIO/SD/MMCLowNo

Description: Note: Apalis iMX8 V1.1A and later do have C silicon or later PMICs which do no longer exhibit this issue and have successfully been validated with various vendor's UHS-I cards to perform at reasonable 85MB/s.

Certain vendors higher-speed UHS-I SD cards may fail due to NXP PMIC Errata ER021: VSELECT incorrect set point. E.g. on SanDisk Ultra or Extreme cards the following may be observed:
[ 290.252408] mmc2: host does not support reading read-only switch, assuming write-enable
[ 290.420738] mmc2: Tuning failed, falling back to fixed sampling clock
[ 290.427228] mmc2: new ultra high speed SDR104 SDHC card at address aaaa
[ 290.434886] mmcblk2: mmc2:aaaa SC16G 14.8 GiB
[ 290.485876] mmc2: Tuning failed, falling back to fixed sampling clock
[ 290.492630] mmcblk2: error -84 transferring data, sector 0, nr 8, cmd response 0x900, card status 0xb00
[ 290.587997] mmcblk2: p1 p2
[ 291.053334] EXT4-fs (mmcblk2p2): mounted filesystem with ordered data mode. Opts: (null)
[ 291.095778] FAT-fs (mmcblk2p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.

Workaround: Disable UHS-I modes by adding the property no-1-8-v to the affected usdhcX node. - or - Try slower or other vendors SD cards. Eventually, this issue will get fixed in a later NXP PMIC die revision.
