Coreboot with a Linux kernel and initramfs as payload.

[Hoàng Tùng]

Hi all,

I'm trying to build Coreboot with a Linux kernel and initramfs as payload.
Here is my step to do it
1. Download souce code Coreboot , linux-2.6.34.13 , busybox-1.20.2
2. Build busybox and make rootfs ( i build static  )
$ cd busybox-1.20.2
$ make menuconfig
$ make
$ mkdir _install
$ make install
        $ cd _install
        $ find . | cpio -o --format=newc > ../rootfs.img
        $ cd ..
        $ gzip -c rootfs.img > rootfs.img.gz
3. Compile a minimal linux kernel
$ cd  linux-2.6.34.13
$ make menuconfig
$ make
4. Convert the kernel image and rootfs to ELF
        $ mkelfImage --kernel=bzImage --ramdisk=rootfs.img
--output=payload.elf
5. Compile Coreboot for qemu using this payload.elf as payload
6. Start qemu using Coreboot.rom
       $ qemu -bios coreboot/build/coreboot.rom -hda disk.img -nographic

But result is failed. QEMU hang out and can't continue
Below is qemu log.

Could you give me some advice ??
Thanks
