afair there was a bug if system was booted from emmc it cannot rebooted to emmc again…@graphine can you confirm this? I guess this behaviour is caused by preloader which is maybe not called again on reboot.maybe it will be fixed by new bootmode (opensource atf which also adds new preloader)

also scripts for creating images were broken and afaik recently fixed in master (based on shebang-line using sh instead of bash causing echo not supporting -e flag)

Follow below steps and try it again.

  • Target Images -> Kernel partition size -> set 20MB ; why my menuconfig have no this choice
