Is my rockpro dead?

[Rocklobster]

Hello,

After years and years of loyal service my rockpro64 quit on me. I had some slow network problems this week, but now it stopped completely.

I have an official power supply. No overheating and I didn't handle it physically.

Only the power light comes on but not the white one also no blinking or anything special. I also tried removing the mmc and inserted a new microSD with a manjaro distro on it.

question : Is it worth it to get an UART cable or did it just die out of old age?

Not sure what Distro your board was running on originally but try Armbian on an SD card. It's a good test reference for those boards.
