Hello,
I selected "Run GOP Driver" for graphics initialization mode and I put a valid VBT binary. FSP somehow quits before even executing PeiGraphics-EntryPoint. In my opinion, if it didn't quit there, it would successfully initialize graphics. I wonder how that happens. After Serialloinit, FSP does PCI enumeration and then notifys "Ready to Boot". It is strange.

coreboot needs to initialize the display and provide the framebuffer for edk2 to use. What display init option do you have selected? It needs to be 'RUN FSP GOP' and a valid VBT is needed for the FSP PEI GOP driver to successfully execute

Hello all,I have a custom CFL board. I used Tianocore UEFI payload. It boots without problem on console and I can enter BIOS menu. I put appropriate vbt.bin file and added that path to config file, so VBT exists. However, I cannot get display output. I inspected debug log and it says "graphics hand-off block not found" in one line. I understand that FSP does not build "gEfiGraphicsInfoHobGuid". Do you have an idea why FSP does not produce that HOB? In addition to that, by using FSP debug binary, I can see that FSP does not even enter PeiGraphicsEntryPoint. It somehow quits after "SerialIoInit() Start" and notifys Post PCI Enumeration.
