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?
