I have built coreboot image for Apollo Lake and trying to boot Oxbohill CRB but no console or display at HDMI port.

This is an 8 MB image, I flashed it to SPI flash at address 0. When I boot the board no output is observed either on USB serial console or on HDMI display.
Do I need to add something more to see at least coreboot log. I am tryng to use GRUB2 as payload to coreboot.
