Hi, I am developing coreboot along with Uefipayload for CFL H RVP11 CRB.
I have added the required binary files (me, desc, ec and gbe) by extracting from the BIOS image. I have also extracted and added the vbt.bin from BIOS to coreboot. For graphics initialisation, i selected "Run a GOP driver" and for Framebuffer mode, i selected "Linear high resolution framebuffer". Compiled and loaded the coreboot image with above configuration. Coreboot booted and the debug prints are displayed in UART port, but nothing came in the graphics. The Display is connected to the DP port of the CRB. And i checked the debug prints, there it is mentioned as "GMA: Found valid VBT in CBFS" and in the next line "Graphics hand-off block not found". >From the above prints i assume that the vbt.bin is proper but still the FSP is not returning the graphics HOB. I am using coreboot 4.17 for my development. Is there any other configurations need to be done with respect to integrated graphics? Regards, Moorthi S
