On Intel NUC DN2820FYK (Atom based), Yocto Linux is unable to start correctly due to bootloader. The EFI boot method is used. Core based NUCs work fine. meta-intel HEAD: 1ce13b3d39b2da79916e3a175cee6baa507290f1 poky HEAD: 698c74c373110ed081a7586e21d4a27b8b44c89b The system gets past the options of boot or install, but the screen goes black and after some time the system returns to the bootloader (grub) menu, but it is stuck, no option can be selected.
Workaround: Add EFI_PROVIDER = "gummiboot" into conf/local.conf file for your build dir.
Retested this with 3 different NUC and minnowboard MAX/Turbot and could not reproduce this issue, not sure if this is specific to the FYK, which I think is an older NUC (EOL'ed)
Since this NUC is EOL, wontfix anyway. On other NUC is working ok.
