Issue: In imx8qxp-cpu board suddenly minicom logs stopped coming. Earlier on minicom shell the logs were coming.
If we flash the board with Android compatible BSP, then the following logs are observed in /dev/ttyUSB1 shell after booting the system.

Via adb I was able to access the shell and do everything I can. It means system is booting up, it is just that serial console is not accessible completely, not sure, why?
I've tried flashing the board with linux yocto BSP via uuu, but still not able to get the console output in any of the tty shell available. /dev/ttyUSB0 or /dev/ttyUSB1.
Command used to flash: sudo uuu <image_name>
After flashing the board is not showing any output on minicom console. So, not sure where is the issue and how to fix the same.
Anyway please give any direction to resolve the same. My target is to get it running with linux yocto BSP.
Thanks & Regards
