IMX8MQ - Android - System crash and reboot when wifi connection is established

I am trying to figure out a wifi issue on Android which causes the system to be crashed and rebooted. When I have a wifi connection or even search for available networks, suddenly the system is restarted due to some reason. Is there anyone who can shed some light on how I can debug or solve the issue?

here are the logcat output AND the system log before restart:

the system log is pretty interesting and according to that log seems there is an issue related to memory

Hello,

 

What I can see is that the device is not complete programmed with Android and the when it comes to a wifi functions is broke up, so please try to burn out the image again, and then if the problem persist go with em_sbc.

Regards

Hello @Bio_TICFSL .

Thanks for your reply, Yes I agree. This issue only happens when I enable wifi.

One thing that you meant by burning out the image again is re-flash the same image to the sd card again. If so, the image is the same image, so what will change? I will definitely try it but just curious.

And One more thing also. what does em_sbc mean? Can you please elaborate on it?

Regards,

Zafer
