You can try to append the dtb to the kernel. Adapt the correct dtb file for you need. $ cat ./vmlinuz ./armada-370-mirabox.dtb >> ./zImage-mirabox $ mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n linux+dtb -d ./zImage-mirabox ./uImage $ mkimage -A arm -O linux -T ramdisk -C none -a 0x00000000 -e 0x00000000 -n "debian installer ramdisk" -d ./initrd.gz ./9016-4EF8/uInitrd Then do the boot as usual.
