Introducing system development workflows


When customizing the software, there are some system development workflows that are commonly used, and we will introduce them in this recipe.

How to do it...

We will see an overview of the following development workflows:

  • External development

  • Working directory development

  • External source development

They are all used under different scenarios.

How it works...

Let's understand what the use of each of these development workflows is individually.

External development

In this workflow, we don't use the Yocto build system to build our packages, just a Yocto toolchain and the package's own build system.

The resulting source can be integrated into Yocto in the following ways:

  • With a recipe that fetches a released tarball.

  • With a recipe that fetches directly from a source-controlled repository.

External development is usually the preferred method for U-Boot and Linux kernel development, as they can be easily cross-compiled. Third-party packages in Yocto are also developed...
