I've been using ./compile.sh to play around booting a NanoPi Neo via FEL and come across an issue when using the default branch. When I build using "BRANCH=dev" it boots but when using 

 

./compile.sh KERNEL_ONLY=no BRANCH=default BOARD=nanopineo PROGRESS_DISPLAY=plain RELEASE=jessie BUILD_DESKTOP=no ROOTFS_TYPE=fel

 

The resulting kernel doesn't boot and shows the following error via serial on the Neo.

 

"Error: unrecognized/unsupported machine ID (r1 = 0x00000000)"

 

I found extracting output/cache/sdcard/boot/boot.scr, adding "setenv machid 1029" and generating the boot.scr image again I was able to get it to boot. Have I missed a step in the compile.sh process when using "BRANCH=default"?

 

Thanks.

Workarounds for FEL boot on sun8i are documented here: http://docs.armbian.com/Developer-Guide_FEL-boot/

Currently it is not automated, but I'll try to implement setting machid for sun8i from the code in the future.
