Hi, We are developing coreboot along with UEFI shell payload for Coffelake architecture. We are using the processor integrated graphics controller for display.
I am getting the following error on porting the coreboot. Grahics hand-off block not found.FSP did not return a valid framebuffer. I checked internal graphics is enabled in FSP and graphics memory is set to 32 MB. Also applied a patch found in coreboot mailing list on device tree and gpio files for Intel graphics. Whether Coreboot can print any messages on the display (other than console). Coreboot came up and I got the shell prompt on Uart Console. The same shell prompt has to come on the display (monitor) but not displayed. I suspect some graphics initialization problem. Regards,gsen.
