Hello everyone, I am trying to build an Intel platform's customized UEFI. I have extracted the microcode and FSP binaries from the vendors UEFI image successfully. I also changed the PlatformPkg and FspFlashOffset FDF files. Execution goes on fine up until the last line of this subroutine:
FspHeaderFound: ; Get the fsp TempRamInit Api address mov eax, dword [edi + FSP_HEADER_IMAGEBASE_OFFSET] add eax, dword [edi + FSP_HEADER_TEMPRAMINIT_OFFSET] ; Setup the hardcode stack mov esp, TempRamInitStack ; Call the fsp TempRamInit Api jmp eax I have checked the address of TempRamInit Entry which matched the address inside the FSP header. but somehow it doesn't return to the TempRamInitDone subroutine. I have no idea why this happens. I also changed the UPD parameters to match the signature of the target platform. Any thoughts on this? -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
