Re: cbfsdisk not found
Actually we are using bit older version of coreboot (pre fmap
implementation) So we took intel help and they provided us base location
(in RAM) where coreboot is loaded and then we calculated as follows which
is working for me.
ptr = *(grub_uint32_t *)(LOADING_BASE + COREBOOT_ROM_SIZE - 4);
head = (struct cbfs_header *) (grub_addr_t) (((COREBOOT_ROM_SIZE + ptr)&\
(COREBOOT_ROM_SIZE -1)) + LOADING_BASE);

Re: cbfsdisk not found
@Vladimir I do not have serial console (board has memory mapped uart not support in grub) to capture memory details. Also on graphics console I can not give commands from usb keyboard to dump memory because USB port on board are 3.0 and USB 3.0 is not supported in Grub. Any other thing I could try? @Andrei What is the expected address supposed to be printed for successful identification of CBFS. I am building coreboot image myself and stitching with other intel firmware as documented by Intel.
