@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.
