boot.img is just a fat32 fs containing all of the usual /boot files, you can just mkfs.vfat the file, and mount it with -o loop, copy the dtb, kernel8.img, start4.ef and fixup4.dat in, umount, and then rpiboot itOk, so if i wanted to do it with rpiboot, i would have to compile my custom kernel8.img, somehow use buildtool to turn it into a boot.img (it's not a linux kernel so idk if it would work) and use rpiboot to send it to the pi?
