Detect OS boot failure and attempt to restart?

Autonomous Machines Jetson & Embedded Systems Jetson Nano

Hello!
Nano sometimes can fail to boot (rare but can happen especially if SD card is not so new) and is problematic in remote unattended installations.
I use B01 developer kit.
Is it possible to somehow implement some kind of a watchdog in Nano that detects that OS has not booted successfully and to attempt restart the device ? I guess e.g. maybe in bootloader or some other way UNDER the operating system ?

can you share the failed log?
if filesystem is not mounted, then system will panic eventually and reboot

There is a error screen (upon failed boot) , but sometimes screen is blank and no message at all…

Logs of what occurs previous to this probably matter. If you can provide a serial console boot log more could be learned about what is going on prior to this. For serial console boot logs, see:
