It seems efiboot may need some tweaks to deal with the memory map of non imx systems: bbb DRAM bank = 0x00000000 -> start = 0x80000000 -> size = 0x20000000 TLB addr = 0x9FFF0000 relocaddr = 0x9FF57000 reloc off = 0x1F757000 irq_sp = 0x9EF36EC0 sp start = 0x9EF36EB0 loadaddr=0x82000000 kernel_addr_r=0x82000000 fdt_addr_r=0x88000000 ramdisk_addr_r=0x88080000 cubox DRAM bank = 0x00000000 -> start = 0x10000000 -> size = 0x80000000 TLB addr = 0x8FFF0000 relocaddr = 0x8FF64000 reloc off = 0x78764000 irq_sp = 0x8F563ED0 sp start = 0x8F563EC0 FB base = 0x8F568FE0 loadaddr=0x12000000 kernel_addr_r=0x12000000 fdt_addr_r=0x18000000 ramdisk_addr_r=0x13000000 efiboot looks for a free 32MB block of memory on a 256MB boundary starting at 0x10000000 Changing it to start searching at 0x80000000 allows efiboot to work on bbb but obviously isn't a proper fix. I've put up a BOOTARM.EFI with this change at http://jsg.id.au/openbsd/BOOTARM.EFI SHA256 (BOOTARM.EFI) = 539ba94277647e3b4ac518ea9941460d02ade4c9119c5e10ed3ff3b70e90429f Copy that to efi/boot/bootarm.efi on the fat FS of your boot device.
