5V PSU fixed it

It seems it might be realted to the USBC PD not working, Trying now with a 6.5A 5V PSU

Hello, I have been able to boot the offical debian image recommend for the rock pi 5b from a NVME SSD. This is after updating the SPI using the windows software. I now cant seem to get armbian to boot from NVME or SD card. I have serial access to the Rock 5b and get the following see attached. Anyone able to point me in the correct direction. I think i need to flash the rock pi so it boots from SD once more. Thanks Matt Rock 5b Armbian fail.txt
