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.

Grasping the BitBake Tool

In the previous chapter, we learned about metadata, metadata collection concepts, and the importance of conf/layer.conf. In this chapter, we will examine metadata more deeply, understand how recipes depend on each other, and see how BitBake deals with dependencies.

In addition, we will cover a massive list of tasks, from downloading source code to generating images and other artifacts. Some examples of these tasks are storing the source code in the directory used for the build, patching, configuring, compiling, installing, and generating packages, and determining how the packages fit into the generated images, which we will introduce in this chapter.
