I have compiled coreboot from master branch (63fd650e2e) and flashed it to a CompuLab Intense PC following this guide:
https://watchmysys.com/blog/2017/12/coreboot-compulab-intense-pc-mintbox/
My problem is that video ouput is missing during POST, only after Linux kernel starts booting, video output become available. This problem is described in the guide and the solution is to include Intel VGA BIOS, which I have done, but still no video ouput before Linux kernel.
The guide is two years old, maybe something has changed in coreboot since then, so more steps are required to get the video working?
This is my defconfig:
CONFIG_USE_BLOBS=y CONFIG_VENDOR_COMPULAB=y CONFIG_VGA_BIOS=y CONFIG_VGA_BIOS_FILE="3rdparty/blobs/mainboard/$(MAINBOARDDIR)/ipc_vbios.rom" CONFIG_INTEL_GMA_VBT_FILE="3rdparty/blobs/mainboard/$(MAINBOARDDIR)/ipc_vbt.rom" CONFIG_ENABLE_MSATA=y # CONFIG_DRIVERS_INTEL_WIFI is not set CONFIG_IFD_BIN_PATH="3rdparty/blobs/mainboard/$(MAINBOARDDIR)/flashregion_0_flashdescriptor.bin" CONFIG_ME_BIN_PATH="3rdparty/blobs/mainboard/$(MAINBOARDDIR)/flashregion_2_intel_me.bin" CONFIG_GBE_BIN_PATH="3rdparty/blobs/mainboard/$(MAINBOARDDIR)/flashregion_3_gbe.bin" CONFIG_HAVE_IFD_BIN=y CONFIG_HAVE_ME_BIN=y CONFIG_CHECK_ME=y CONFIG_HAVE_GBE_BIN=y CONFIG_MAINBOARD_USE_LIBGFXINIT=y CONFIG_INTEL_GMA_ADD_VBT=y CONFIG_SEABIOS_BOOTORDER_FILE="bootorder.txt"
Any ideas on what I could be doing wrong?
