This guide shows how to build Dasharo firmware for Hardkernel devices.

Requirements

• Docker

  • sudo apt-get install git

Building

To build Dasharo firmware image, first clone the coreboot repository:

git clone https://github.com/Dasharo/coreboot.git

then follow the steps below:

1. To build a specific version checkout to the version's tag. Skip this step otherwise.

   cd coreboot
   git checkout hardkernel_odroid_h4_<version>
   

   For example

   git checkout hardkernel_odroid_h4_v0.9.0
   

2. Checkout submodules:

   git submodule update --init --checkout
   

3. Build the firmware:

   ./build.sh odroid_h4
   

   The resulting coreboot image will be placed in the coreboot directory as hardkernel_odroid_h4_<version>.rom.
