This is one of the next hours :-). :

Now I swap out the uSD while device-power is on ( so that only the nvme has freebsd installed)

not sure to post an freebsd-bug-report because it could be u-boot or hardware-related like Søren Schmidt described : <<(I use older Intel 660 IIRC uses only 3.5W max), otherwise the HW cant cope..>>


Drive is a WD-blue nvme (M-key), directly plugged into the M.2-slot of the Rock960 ,
Doesn't matter whether 12V/2a (default plug) or 12V/3a is used .

The real strange thing is that it definitely boots up from nvme.

Original u-boot-patch is :

Thanks for reading
