I bought an Argon One V2 box with the NVME expansion board.
I started by installing raspberyOS on an sd card in order to change the boot order to USB and choose the correct bootloader.
The SSD is clearly visible when I boot from an SD card with the lsblk command.
I then flashed my Crucial P5 Plus SSD with an image of RaspberryOS from my PC then I reinstalled it in the NVME expansion board and removed the SD but could not get it to boot with the Argon NVME board. No display on the HDMI, the green led of the PI is lit without flashing
With another USB 3.0-> NVME adapter the raspberry boots correctly.
Have you encountered this problem before ?
