Building manual

Intro

This document describes the procedure for compiling coreboot for Protectli VP4630, VP4650 and VP4670.

Requirements

Build Dasharo BIOS firmware

This build procedure produces full firmware binary including blobs such as FSP, and ME. Currently, access to them is restricted to the OEM (Protectli) via a private repository.

Since version v1.0.18 VP4630 and VP4650 use different configuration file than VP4670. Versions v1.0.17 and older do not support VP4650 and VP4670 at all.

Versions v1.1.1 and newer support all variants with a single binary.

  1. Clone the coreboot repository:

    git clone https://github.com/Dasharo/coreboot
    
  2. Checkout the desired version, e.g. v1.1.0:

    cd coreboot
    git checkout protectli_vault_cml_v1.1.0
    
  3. Checkout submodules:

    git submodule update --init --checkout
    
  4. Obtain the Protectli blobs package (only for version v1.1.0 and older):

    Replace <PROTECTLI_BLOBS_REPO> with a a proper path to the repository in a form of: git@repo-path.git. You should checkout to the same tag as in case aof the coreboot repository.

    cd 3rdparty/blobs/mainboard/
    git init
    git remote add origin <PROTECTLI_BLOBS_REPO>
    git fetch origin && git checkout protectli_vault_cml_v1.1.0
    cd -
    
  5. Build the firmware:

    ./build.sh vp46xx
    

    The resulting coreboot image will be placed in the coreboot directory as protectli_vault_cml_<version>_vp46xx.rom.

    ./build.sh vp4630_vp4650
    

    The resulting coreboot image will be placed in the coreboot directory as protectli_vault_cml_<version>_vp4630_vp4650.rom.

    ./build.sh vp4670
    

    The resulting coreboot image will be placed in the coreboot directory as protectli_vault_cml_<version>_vp4670.rom.
