In many cases, you can customize an existing linux-yocto recipe to
meet the needs of your project.
Each release of the Yocto Project provides a few Linux
kernel recipes from which you can choose.
These are located in the
Source Directory
in meta/recipes-kernel/linux
.
Modifying an existing recipe can consist of the following:
Creating the append file
Applying patches
Changing the configuration
Before modifying an existing recipe, be sure that you have created a minimal, custom layer from which you can work. See the "Creating and Preparing a Layer" section for some general resources. You can also see the "Set Up Your Layer for the Build" section of the Yocto Project Development Manual for a detailed example.
