(In reply to Ludwig Nussel from comment #4) > I used the image as is so it uses u-boot to load the kernel directly. If we want to use Grub, u-boot config needs to have CONFIG_DISTRO_DEFAULTS=y which is not the case for this board. So, it currently uses boot.scr script which does not have the root="..." info anymore. I can try to enable CONFIG_DISTRO_DEFAULTS=y for this board in u-boot-a10-olinuxino-lime.
