Embedded Linux Development Using Yocto Project Cookbook - Second Edition

By: Alex Gonzalez

Overview of this book

The Yocto Project has become the de facto distribution build framework for reliable and robust embedded systems with a reduced time to market.You'll get started by working on a build system where you set up Yocto, create a build directory, and learn how to debug it. Then, you'll explore everything about the BSP layer, from creating a custom layer to debugging device tree issues. In addition to this, you’ll learn how to add a new software layer, packages, data, scripts, and configuration files to your system. You will then cover topics based on application development, such as using the Software Development Kit and how to use the Yocto project in various development environments. Toward the end, you will learn how to debug, trace, and profile a running system. This second edition has been updated to include new content based on the latest Yocto release.

Describing workflows for application development

The recommended way to approach application development with the Yocto Project is to use either the standard or the extensible Yocto SDK as an iterative interface between the application developers and the system integrators. The latter feed the new software into the Yocto build system to produce and share new SDKs between the application and BSP developers.

However, there are other application development workflows that are useful and these will be introduced next.

How to do it...

We will see how the following development workflows are applied to application development:

  • External development: When using Yocto SDKs
  • Working directory development: When using the Yocto build directory
  • External source development: When using the Yocto build system but configuring an external directory for the source

How it works...

Let's see how the different development workflows work in more detail.
