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

[jean_bruder]

Good evening,

My Rock64 won't boot anymore : the SD card has no issue, the text displayed at the boot is only garbage and after a time the red light is blinking twice quickly and wait 1 second, then twice b;inking again and so on ... 

Could somebody help to understand what happen ?

Many thanks in advance,
Regards,
Jean

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 :
