occasionally, my RPI4 OPA hangs when boot up. it normally stuck at reverse gear video display. once stuck or hang, I need to unplug the power to forcefully turn off RPI. If I do that couple of times, I'm worry that I will lost everything including OS/OPA. is there a way to have combination of keys press to trigger the reboot of RPI and get out of hang state? any suggestion?
My reverse camera is run as a service with CAN bus trigger. my safe shutdown (also a service) is triggered using a pin to detect ACC. when it hangs, it cannot react to ACC signal and did not shutdown either. let me know how to set it up more durable and reliable. thanks.
