Idea

My solution was to build a customized iPXE 3 bootloader image with an embed script that fetches the actual boot instructions. This iPXE image was then signed and placed in the EFI system partition on the emmc as ESP/EFI/BOOT/BOOTX64.EFI. I may make a more detailed guide to this at some point in the near future.

Troubleshooting

  • same problem on forum https://forum.ipxe.org/showthread.php?tid=13245

  • bootx64 is bad

  • ipxe options should be added to nvram https://wiki.gentoo.org/wiki/Efibootmgr

sudo efibootmgr -c -d /dev/sdb -p 1 -l '\EFI\ipxe.efi' -L "iPXE"
