Build Prerequisites

Before building the image, you must set up your development environment with the necessary tools and system resources. This section outlines the required system specifications and installation steps for essential tools.

System Requirements​

To successfully build the image, ensure your system meets the following requirements:

  • Linux-based operating system
  • Minimum 200 GB of free disk space
  • At least 16 GB of RAM
  • Internet connection

Install git​

The git tool is essential for cloning the repository that contains the board support package for Grinn hardware. To install git, follow the instructions on the official Git website.

Install docker​

The docker tool is required to build the image using the kas-container script. It lets you run the build process inside a containerized environment, which ensures consistency and isolation from your host system. To install docker, follow the instructions on the official Docker website.

Set up kas-container​

Grinn uses the kas build tool to manage the build process. It significantly simplifies the process of building Yocto-based images by abstracting away the complexities of the underlying build system.

To ensure the same build environment across different systems, the kas-container command is used. It is a simple wrapper around the docker command that runs kas inside a container. This approach eliminates the need to install kas directly on your host system.

To install the kas-container script, run the following commands in your terminal:

wget -qO kas-container \
https://raw.githubusercontent.com/siemens/kas/refs/tags/5.3/kas-container
chmod +x kas-container
sudo mv kas-container /usr/local/bin/
