What I try to do is cross-compile Grub2 for arm64 (also called aarch64) for the HiKey board. I use a x86_64 virtual machine running Debian "Stretch" (Testing) on my Laptop to cross-compile Grub2.
I use grub-mkimage, because the developer from the HiKey board gave me some instructions (see: http://www.96boards.org/forums/topic/grub2-cant-find-command-multiboot-and-module/#post-16820). I try to adjust the instructions to my own needs, but have little to no experience with the Grub2 commands, such as grub-mkstandalone. In short I am happy about every advice, hint and help I can get. >> --config=out/grub.configfile --format=arm64-efi $GRUB_MODULES >> Prefix not specified (use the -p option). >> Usage: ./grub-mkimage [OPTION...] [OPTION] >> ~~~ >> >> I get the message: "prefix not specified".
