I would suggest enabling SPI flash console, which writes logs to the SPI flash chip. Build, flash, and try booting. Then, power off and read the flash chip back. There should be a log somewhere inside the CBFS. > I also tried different configs use LIBGFXINIT or use VGAROM, and Tianocore or > Seabios payload. Still the same problem.

Ideally, just selecting USE_BLOBS (needed for microcode), selecting the mainboard and adding the mrc.bin should result in a bootable build. It will print a large warning, though: since the IFD/ME/GbE regions were left empty, flashing the result as-is will not work. On the t440p with two flash chips, you only need to flash the last 4 MiB of the 12 MiB coreboot.rom into the 4 MiB chip. libgfxinit should just work. The VBIOS is less likely to work fine on the first try, as extracting it is more error-prone. > The sha1sum of the blobs I obtained are: > $ sha1sum mrc.bin > d18de1e3d52c0815b82ea406ca07897c56c65696 mrc.bin Okay, that matches with the mrc.bin of peppy. The one I use (from wolf) has a different hash, no idea as to why. > $ sha1sum pci8086,0416.rom (obtained through linux kernel) > 4074e1fa2f788f91d3612b6fe861c9c3faf5560a pci8086,0416.rom > > I also tried archfan's repo for T440p but still can't build.

That's good to hear. > _______________________________________________ > coreboot mailing list -- [email protected] > To unsubscribe send an email to [email protected] Best regards, Angel Pons _______________________________________________ coreboot mailing list -- [email protected] To unsubscribe send an email to [email protected]
