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-4852FixedBluetooth Does Not Work Out-of-the-box and Issues With OE OverridesVerdin iMX8M PlusBluetooth, BuildsystemLowNo

Description: Some OE overrides in our layers are using a no longer supported syntax, because of that Bluetooth does not work out-of-the-box on Verdin iMX8M Plus >= V1.1A.

Workaround: Manually execute hciattach: ``` /usr/bin/hciattach /dev/ttymxc3 any 115200 flow /usr/sbin/rfkill unblock bluetooth /usr/bin/hciconfig hci0 up # Change BT UART baudrate to a higher speed, for example 921600 /usr/bin/hcitool -i hci0 cmd 0x3F 0x09 0x00 0x10 0x0e 0x00 /bin/stty -F /dev/ttymxc3 921600 ```

Description: Add support for Bluetooth on Verdin iMX8M Plus V1.1.

ELB-3221New FeatureBring-up UART Interface for Bluetooth (Alternatively to e.g. SDIO)Verdin iMX8M PlusBluetooth, SDIO/SD/MMC, UART, Wi-FiNo

Description: As concurrent use of SDIO Wi-Fi and Bluetooth is causing issues an alternative would be to use the UART for Bluetooth.

5.3.0 (Release date: 2021-07-08)
Embedded Linux BSP Q2 2021 Quarterly Release. Learn more on https://www.toradex.com/news/bsp-layers-reference-images-yocto-project-5-3-0-quarterly

Description: Bluetooth pairing works but connection is not working

Workaround: CONFIG_BT_RFCOMM=m CONFIG_BT_RFCOMM_TTY=y

Not Planned
ELB-3039Known IssueConcurrent Use of SDIO Wi-Fi and Bluetooth May Crash Firmware/DriverColibri iMX6ULL, Verdin iMX8M Mini, Verdin iMX8M PlusBluetooth, Wi-FiLowNo

Description: Simultaneous use of Wi-Fi and Bluetooth interfaces can lead to crashes of the firmware and/or the Linux kernel driver of the SDIO Wi-Fi/BT solution.

Workaround: Unload (rmmod) the entire Wi-Fi and Bluetooth stack and reload (insmod) it again. Worst case an entire system reboot may be required. Note: NXP is still working on the concurrent Wi-Fi Bluetooth use case.
