Requirements

• Docker
  • follow Install Docker Engine on Ubuntu
  • follow Post-installation steps for Linux
• Git

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.

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_ehl_v1.1.0
   

3. Checkout submodules:

   git submodule update --init --checkout
   

4. Obtain the Protectli blobs package (only v1.1.0 or 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 of the coreboot repository.

   cd 3rdparty/blobs/mainboard/
   git init
   git remote add origin <PROTECTLI_BLOBS_REPO>
   git fetch origin && git checkout protectli_vault_ehl_v1.1.0
   cd -
   

5. Build the firmware:

   ./build.sh vp2420
   

The resulting coreboot image will be placed in the coreboot directory as protectli_vp2420_<version>.rom.
