Building coreboot

Preliminaries

Prior to building coreboot the following files are required:

  • Intel Flash Descriptor file (descriptor.bin)
  • Intel Management Engine firmware (me.bin)
  • ITE Embedded Controller firmware (ec.bin)

The files listed below are optional:

  • Splash screen image in Windows 3.1 BMP format (Logo.bmp)

These files exist in the correct location in the StarLabsLtd/blobs repo on GitHub which is used in place of the standard 3rdparty/blobs repo.

Build

The following commands will build a working image:

make distclean
make defconfig KBUILD_DEFCONFIG=configs/config.starlabs_labtop_cml
make
