Introduction

This wiki will provide a detailed guide on how to create a custom Yocto meta-layer.

Create Base Meta-Layer

This section contains steps to create the base custom meta-layer. After completion, the custom base meta-layer will contain the following parts:

• Custom layer configuration
• Custom distro configuration
• Custom machine
• Custom config template files
• Custom image recipe

Step 1. Add base layer.conf file

The layer configuration file provides Yocto with the configuration for the custom meta-layer. It shall be stored in a directory called conf inside the base meta-layer directory, and it shall be named layer.conf. According to the Yocto documentation it is recommended to start from an existing layer.conf file from a different meta-layer and change it according to the custom requirements.

For instance, here is an example of how the directory structure should look after creating the layer.conf file.

#!/bin/bash
echo "Hello, World!"
ls -l /home/user
