coreboot building


This documents describes the procedure for compiling coreboot for NovaCustom NV4X.



The easiest way to build coreboot is to use the official Docker image.

Obtain the image:

docker pull coreboot/coreboot-sdk:0ad5fbd48d

Clone the coreboot repository:

git clone

Navigate to the source code directory and checkout to the desired revision:

Replace the REVISION with one of the: - novacustom_nv4x/release for the latest released version - novacustom_nv4x_vVERSION (e.g. v1.2.1) for the given release

cd coreboot
git remote add dasharo
git submodule update --init --recursive --checkout
git fetch dasharo
git checkout REVISION

Build the firmware:

./ build

The resulting coreboot image will be placed in artifacts/dasharo_novacustom_nv4x_VERSION.rom.

Warning: Do not run ./ as root. This command uses docker and should be executed as your current user. If you're having trouble running on your user account, follow the Docker instructions outlined in Requirements.
