I bought a rockpi. Made a SD debian-image and powered on
Nothing except green led.
Serial console says nothing
Monitor stays sleeping.
I returned it, got another card which is exactly the same
Power supplies tried; RaPi official power supply. Apple 65W charger. Samsung charger.
Various SD cards including SanDisk ultra and extreem
Wrote card with dd. Have made many RaPi bootable cards. Can mount and see pertitions and files on a linux system.
What happens when you power a card?
What happens if a monitor is plugged in?
What happens when SD card is plugged in (then power up)
I want to boot and run from NV m2 so SD card is to bootstrap the m2.
Any other suggestions
