Sufficiently modern Ubuntu does not use U-Boot by default, at least for server builds. ubuntu-22.04.1-preinstalled-server-arm64+raspi.img has: # more /mnt/config.txt [all] kernel=vmlinuz . . . where vmlinux is seen as: /mnt/vmlinuz No use of U-Boot: direct booting of vmlinux via the RPi* firmware's ability to do so. They do provide uboot_rpi_*.bin 's for folks that want to change to use such: /mnt/uboot_rpi_3.bin /mnt/uboot_rpi_4.bin /mnt/uboot_rpi_arm64.bin But the supplied config.txt makes no mention of any uboot*.bin and things have to be changed to cause a uboot_rpi_*.bin to be involved. === Mark Millard marklmi at yahoo.com
