Radxa Rock 4SE. Tried on OS: Debian, Dietpi.
The PCB is only responsive after a new system is installed. It is connected through an Ethernet cable and responds to SSH, casaos etc.
If the power is cut the PCB doesn’t respond anymore. It doesn’t reappear in the router’s IP tables. I’m sitting next to it now, and there is no blue “heartbeat” light.
Any ideas?
Seems like a counterfeit or bad SD-card.
If you want more detail, provide logs from journal on the non-booting SD-card or better, live serial console logs at boot.
I’ve tried several SD cards, some of which were counterfeit (or bad), but at least two weren’t - including the current one.
I’ll try to get the “live serial console logs” the next time. If I understand correctly the live serial will be generated when the pcb boots from the card and i should save the outputs somewhere, and then when it doesn’t I take the card out and copy new logs from it?
Will chatgpt be able to guide me to the right logs?
The journal is on the card itself, so if bad card, it might be corrupted so of no use.
Logs via serial console cable go to another computer, you need terminal program like putty or screen or tabby or minicom, etc. You can just cut and paste the text.
Look in docs how to connect a serial console cable, is very standard, more than a decade, on pins 6 8 10
