Hi.

I try to use the linux kernel as payload in coreboot. I use a bzImage of the kernel.

When I compile, I get the following message:

OBJCOPY    cpu/x86/smm/smm_wrap.ramstage.o
    CC         generated/ramstage.o
    CC         cbfs/fallback/ramstage.debug
    OBJCOPY    cbfs/fallback/ramstage.elf
    CBFS       coreboot.rom
    PAYLOAD    ../bzImage (compression: none)
E: The stage file is not in ELF format!
    CONFIG     .config
    CBFSPRINT coreboot.rom

(empty)                        0x1695c0   null         2713240

Am I wrong assumimg that the image may be a real (compressed) bzImage?

Should I use a vmlinuz better? Or is my bzImage is not suitable (maybe parts of it are compressed or so)?

Thanks.
