Ubuntu 22.04 image beta test for jetson nano

I think the breakage of my jetson nano was caused by my experiments with the USB booting. Don’t use to boot it using the USB port. The code involved in this kind of booting procedure is fragile and maybe bugged. My suspect is that nvidia knows that (I read that some developers expressed some interesting argumentations where they say that there are old problems never fixed totally in some old posts) ,but I’m not sure if the developers agree with that. If this is true,the failure was caused by the code / patched created by nvidia,not by me and I could have the right to have a new board,for free. But I think that this will never happen. I’m sure they will say that the USB booting is a new and experimental feature and that I have been warned. That’s all.
