Hi Simon
Thanks for your reply
I have added u-boot ELF as the coreboot payload
u-boot: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), statically linked, not stripped.
Got this link but its a year old. http://lists.denx.de/pipermail/u-boot/2013-July/159140.html
Thanks Ajoy
Please avoid top posting as it doesn't work well on mailing lists.
I suggest using cbfstool add-flat-binary -f u-boot-dtb.bin -n fallback/payload -c lzma -l <text_base> -e <entry>
For text_base use CONFIG_SYS_TEXT_BASE which is probably 1110000
For entry use _start which is probably 1110015.
Of course I'm not sure whether your problem is with Coreboot, U-Boot or qemu, but we'll see.
Also, please can you reply to the list with instructions when you get it working, or send a patch to doc/README.x86.
Regards, Simon

Hi
Need Help
I want to run U-BOOT as coreboot payload on QEMU platform
I am on uboot-x86 git
Compiled U-BOOT with make coreboot-x86_defconfig and make all

Is QEMU not supported for coreboot and u-boot
I'm not sure it's been tried but there's no reason why it should work. It seems to be crashing in U-Boot before there is any serial output. Did you put u-boot-dtb.bin as the payload?
