Yep, spent days trying the various methods. I’ve installed/mounted NVME disk, 4 SE recognizes it. Installed images (a few times), but 4 SE doesn’t boot from NVME. Get a green light, but never a blue.
If I boot from SD card with NVME installed, I can see the NVME with system files and all partitions.
Instructions on Rockpi4/install/NVME - Radxa Wiki show methods that require SPI which is not present on the 4SE.
So, that’s why I’m stuck.
