I have tried everything, 3 different kind of USB3 to SATA converters, one USB – C to M2 disk testet, 3 different SSD disk, 128 and 256 GB, 2 different image programs, all PI 4 images from 128 GB and down downloaded and testet. Nothing will complete a boot. It boot loops. I have upgradet to latest software on pi, I have overwritten /BOOT files fix… and elf files. The only thing that works is when I test the small images under 32 GB on a SD card. Anyone know what could be the problem. If it is the USB to SATA converts, then maybe a ebay link to a device somone know is working. Mostly it is the batocera that got my attension.
