Embedded Linux Development Using Yocto Project - Third Edition

By: Otavio Salvador, Daiane Angolini

Overview of this book

The Yocto Project is the industry standard for developing dependable embedded Linux projects. It stands out from other frameworks by offering time-efficient development with enhanced reliability and robustness. With Embedded Linux Development Using Yocto Project, you’ll acquire an understanding of Yocto Project tools, helping you perform different Linux-based tasks. You’ll gain a deep understanding of Poky and BitBake, explore practical use cases for building a Linux subsystem project, employ Yocto Project tools available for embedded Linux, and uncover the secrets of SDK, recipe tool, and others. This new edition is aligned with the latest long-term support release of the aforementioned technologies and introduces two new chapters, covering optimal emulation in QEMU for faster product development and best practices. By the end of this book, you’ll be well-equipped to generate and run an image for real hardware boards. You’ll gain hands-on experience in building efficient Linux systems using the Yocto Project.

Summary

This chapter presented the basic concepts of packaging, which has a significant role in Poky and BitBake (package versioning), and how this impacts Poky’s behavior when rebuilding packages and package feeds. It also showed us how to configure an image to be updated using prebuilt packages provided by a remote server.

In the next chapter, we will learn about the BitBake metadata syntax and its operators and how to append, prepend, and remove content from variables, variable expansions, and so on. We will then be able to better understand the language used in Yocto Project engines.
