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

In this chapter, we learned how to configure Poky to help us with the debugging process. We learned about the contents of deployed directories that can be used for debugging and how we can track our changes using buildhistory. We also covered the use of oe-pkgdata-util to inspect package information, use bitbake-getvar to debug variable expansion, how we can use devshell to emulate the same build environment found by BitBake, and how we configure our system to provide the tools needed for GDB debugging.

In the next chapter, we will learn how to expand the Poky source code using external layers. First, we will introduce the concept of layering. Then, we will learn in detail about the directory structure and the content of each layer type.
