Other Parts Discussed in Thread: AM4372
Hi,
I recently updated our yocto image to the most recent TI SDK Version 6.x. The prior version we are using was the Version 5.2.x. After the update the Wifi/Bluetooth device is not probed anymore. I do not have any mlan0 device anymore after running ifconfig -a.
Following some additional information and logs. I have also attached the full dmesg log.
Please let me know if you need any further information.
Configuration
Used Kernel: 4.19.38-rt19 armv7l GNU/Linux
