imx8mq android customized board reboot randomly

[edward_fu]

Hi experts,

I am working on a customized board based on i.MX8MQ processor.

My Boards(more than 50 boards) all reboots randomly. It occurs after one or two day. When I refer the log message(by uart serial port) I couldn't able to find the root cause of the problem. Nothing shows up in serial console, it's just like you unplug the power and things stop suddenly.

Could anyone give me some suggestions?

Thanks very much.

Please try to capture provide all logs including kernel and android.

Hi,

There is lots of my customized hal and android apk log. You can refer it. After reboot, I input logcat in the serial port. 30 minutes later, system suddenly reboot and serial no output.

Thanks

Hi @edward_fu 

I find the log contains lots of error about vendor.trt.rvm.controller service. Can you check this service? Disable it and test again.

D vendor.trt.rvm.controller Protocol Handle: M4  =>      A53     ReportErrorReq(0x0D): 0x80 0x05 0x00 0x02 0xff

Do you have any suggestions or solution?

Hi @edward_fu 

The log file contains lots of D vendor.trt.rvm.controller, can you only share kernel log?

[edward_fu]

That's my logical business log. It doesn't matter.

One thing to be highlight, when I disabled watchdogd(/vendor/bin/watchdogd) not kernel watchdogd daemon, the system will stuck not reboot.
