I am not on JeOS. I referred to Debian. This the result for sunxi: pine64_plus_defconfig: fdtfile=sun50i-a64-pine6-plus.dtb According doc/README.pxe ftdfile was never meant to contain a path. If you want a path this should be defined as ftddir. So Odroid C2 is buggy and we should clean up the fdtfile variable.
