I have a Jetson Nano since few weeks that I was using for astrophotography application with an IMX477 sensor. It is installed in a metal case with power on, reset and FR mode buttons. The kind of case very common on online shopping sites.
Suddenly few days ago it started to randomly power off, I had to manually push the power on button to restart it. After a while of this behaviour it never come up again.
I can power on, the green led turns on, but no system is booted.
I connected the serial debug port and I see the following repeated in loop:

I tried to write a new SD but I have the same behaviour.
Do you know what is happening and how to solve the problem?
Unfortunately I have ubuntu 20.04 and I have some difficulties running the SDKManager.
