No boot, garbage console text and blinking red light ...

[jean_bruder]

Sounds like it might be power supply related. Do you have an alternative power supply. you could try.

The power supply has  been purchased with the board ... I wonder why would the power supply be broken as it is only used to power the Rock64 board

OK, got some console output, and now the system hang with a kernel panic, or boot in emergency mode ... What goes wrong ?

Here's the output of the output :
