Embedded Linux Development using Yocto Projects - Second Edition

By: Otavio Salvador, Daiane Angolini

Overview of this book

Yocto Project is turning out to be the best integration framework for creating reliable embedded Linux projects. It has the edge over other frameworks because of its features such as less development time and improved reliability and robustness. Embedded Linux Development using Yocto Project starts with an in-depth explanation of all Yocto Project tools, to help you perform different Linux-based tasks. The book then moves on to in-depth explanations of Poky and BitBake. It also includes some practical use cases for building a Linux subsystem project using Yocto Project tools available for embedded Linux. The book also covers topics such as SDK, recipetool, and others. By the end of the book, you will have learned how to generate and run an image for real hardware boards and will have gained hands-on experience at building efficient Linux systems using Yocto Project.

Summary


In this chapter, we learned the reasons that motivate us to create a new layer and metadata. We saw a description of how to create machine configuration, a distribution definition, and recipes files. We learned how we can create images and how to include our application in an image.

In the next chapter, we will access some examples of the most common customization cases used by an additional layer, such as modifying existing packages, adding extra options to autoconf, applying a new patch, and including a new file to a package. We will see how to configure BusyBox and linux-yocto, two packages commonly customized when making an embedded system.
