Embedded Linux BSP Q4 2022 Quarterly Release. Learn more on https://www.toradex.com/news/bsp-layers-reference-images-yocto-project-6-1-0-quarterly |
ELB-4852 | Fixed | Bluetooth Does Not Work Out-of-the-box and Issues With OE Overrides | Verdin iMX8M Plus | Bluetooth, Buildsystem | | Low | No |
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

ELB-3039 | Known Issue | Concurrent Use of SDIO Wi-Fi and Bluetooth May Crash Firmware/Driver | Colibri iMX6ULL, Verdin iMX8M Mini, Verdin iMX8M Plus | Bluetooth, Wi-Fi | | Low | No |
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. |
