I use SanDisk Extreme Pro 128GiB flash drives in the RPi 4b USB 3 port,
sometimes with a 6" USB 3 cable.
I can always boot RPi OS on these drives. I have never been able to boot
NetBSD 10.
I downloaded the arm64.img, and RPi4_UEFI_Firmware_v1.35.zip. On a Linux
desktop:
dd if=arm64.img of=/dev/sda bs=1M
and, then I replace the corresponding files from
RPi4_UEFI_Firmware_v1.35.zip.
mount /de3v/sda1 /mnt
cd /mnt
unzip ~/NetBSD/RPi4_UEFI_Firmware_v1.35.zip
When I attempt to boot, I see the color flash, then a cursor at the top
left of the screen, then the screen goes blank.
he flash drive shows lots of accesses during this process and then shows
access flashes in groups of 3 or 4. I think this indicates an unreadable
file, I think.
When I do the the same actions with an SD card, NetBSD boots.
What do you do?
