I recently bought a Pi 5, 16GB, an Argon ONE V3 M.2 case and a Western Digital SN850 NVMe drive.
I was able to get an SD card imaged from the network installer, modified the config.txt to allow the NVMe drive to show up, channged the EEPROM to allow NVMe boot, and cloned the SD card to the NVMe drive using rpi-clone. Used the Argon scripts for the configt and EEPROm modifications. I’m able to mount and check all the files in the NVMe drive. However, any time I try to boot from it I get the following:
brcm-pcie 1000110000.pcie: link down
And it only boots into BusyBox.
No idea where to go from here, as I’m able to see the drive with lsblk, mount it, work with it and everything else, I just can’t boot from it.
