Most commonly this has been because of a microcode mismatch with the populated processor. Update edk2-non-osi/Silicon/Intel/WhitleySiliconBinPkg/IcxMicrocode with microcode matching a successfully booting image and rebuild. Less common, but possibly helpful is taking your existing, booting RVP binary image, and using a hex editor to replace the BIOS region of the 64MB image with the 16MB BIOS binary image built. Replace 0x03000000 to 0x03FFFFFF with the 16MB O:\Build\WhitleyOpenBoardPkg\DEBUG_VS2015x86\FV\WILSONCITYRVP.fd Ensure you have BootGuard disabled and considerations like that. We have occasionally seen issues with variants of WilsonCity HW that aren’t currently functional in the open code. If microcode doesn’t correct the issue, we can share logs and hardware details privately and see if we can’t identify the issue from a working log. I installed WSL with Debian and I was able to build and boot successfully. I think that you are past these issues, but here are some config details just for your reference. gcc version 10.2.1 20210110 (Debian 10.2.1-6) Python 3.9.2 (default, Feb 28 2021, 17:03:44) NASM version 2.15.05 Intel ACPI Component Architecture ASL+ Optimizing Compiler/Disassembler version 20200925 Regards, Isaac From: Akber Basha J Sent: Wednesday, May 18, 2022 11:26 PM To: devel ; Oram, Isaac W Cc: Desimone, Nathaniel L Subject: Re: [edk2-devel] EDK2 WilsonCityRVP BIOS Build Error Hello Issac, When trying to boot the generated BIOS image on WisonCityRVP platform, we are getting only blank screen.

Yes, the patch is working fine for both JunctionCity and WilsonCityRvp. I will boot it on WIlsonCityRvp. If got any issues, will let you.

In the meantime, this workaround procedure worked for me: export WORKSPACE=~/src export EDK_TOOLS_PATH=~/src/edk2/BaseTools cd ~/src/edk2 make -C BaseTools . edksetup.sh BaseTools cd ../edk2-platforms/Platform/Intel/ python build_bios.py -p WilsonCityRvp -t GCC5 -d The problem as I currently understand it is that the pre_build_ex board specific extension is being run before the edk2 build environment is set up by the build_bios.py script. The workaround effectively creates the environment needed to perform the pre-build steps. I will confer with Nate on the correct fix for this. It seems like we might need another extension point after ed2 build environment and before main build, but maybe there is a more elegant solution. Also note that there has been an initial report of a binary compatibility issue between the FSP binary and the gcc built bootloader. At this time it is not expected to boot properly. The issue reported was only with enabling a second SATA drive. But if there is a binary compatibility issue in the API, any number of things might be incorrect functionally with GCC built edk2 WhitleyOpenBoardPkg bootloader.
