Why is jetson nano reboot not showing up on the screen? It was still able to reboot before

I used to be able to use Jetson nano, but I turned it on two days ago, and nothing happened to it, why and how to solve it.

Dump the log and it shall tell us the reason why it gets stuck.

I am currently using a jetson nanao 2gb board.

The uart pin on the nano 2gb board is mentioned here. Please use that to dump log.

This guy’s case so far shares the same debug flow as your case. You can refer to it too.

I want to make it find more VNC, is there any solution?
