so.... check LABEL= is right,,,, sudo blkid ,,,, and that the dtb is where stated, not in a dtb directory
the line(s) linux /vmlinuz-5.10.0-13-arm64
Strongly suggest that /boot is a separate partition, should show that in blkid above
If there is only 1 partition, that is wrong
explanation: uboot looks for (and I'm not sure what order) boot.scr, extlinux/extlinux.conf, efi/aarch64.efi
(or boot/boot.scr,, boot/extlinux/extlinux.conf ,,, etc)
If there is only 1 partition, those are preceded by /boot/
If there are 2, well, fstab and mounting has not happened yet, so as far as uboot
knows, these are in the root of what uboot recognizes as the file system
If you have a 3.3V serial cable and flip the headphone/serial switch then you will know more
Even then, some dtb's do not set up video correctly
My extlinux.conf for buster also has (in the append line) modprobe.blacklist=panfrost
and maxcpus=6 (This will just make it a LOT slower,using the 4 m55 cores)
