(It might work if you use kernel.bin and compile it with > LINUX_BOOT_ABI). I got it to boot by having a fat32 partition with just the kernel and a = /extlinux/extlinux.conf file on it, then it boots just fine. It see the eMMC and the SD-card so it should be able to get to a shell = at least, need to get my build script finished. I=E2=80=99ll check your patches from GitHub and get it integrated so the = ball can start rolling :) Thanks for getting us this far!! -S=C3=B8ren=
