Hay, beginner here
Im trying to run ubuntu on my rock3a. I flashed the image from the radxa’s GitHub (rock-3a-ubuntu-focal-server-arm64-20221101-0219-gpt.img.xz) and followed their installation wiki. But when I plug in power and my monitor it doesn’t boot. I would love to learn why it’s not working
Last line is:

4.699300] systems[1]" set hostname to
I tried armbian, demian and ubuntu and it all came down to the same issue. It runs some code, its looking like its fully booting (even saying welcome to ubuntu LTS for example) but then it cuts power, goes to a black screen and stops working. After this is tries to start booting again repeating the same failed startup.
