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
