Book Description

The Yocto Project powers some of the world's most demanding embedded Linux products, from medical devices and industrial gateways to networking gear and consumer electronics. With this book, you join the engineers who rely on it every day to ship reliable, reproducible Linux systems.

Embedded Linux Development Using Yocto Project, 4th Edition, is your hands-on guide to the Yocto Project 6.0 (Wrynose) LTS release. You'll move from your first QEMU boot to a custom production distribution running on real hardware, mastering Poky and BitBake along the way. The book covers custom layers and recipes, the Standard and Extensible SDKs, Toaster, package feeds, Build History, devshell debugging, and GPL compliance backed by SPDX 3.0 SBOMs and CVE scanning.

A brand-new chapter on Managing BitBake Configuration walks through the bitbake-setup and bitbake-config-build workflows reshaping how teams bootstrap, share, and reproduce builds. You'll package BitBake Configuration Templates and Fragments, manage registries, and synchronize configurations across teams.

By the end, you'll be ready to bake images for BeagleBone Black, Raspberry Pi 4 and 5, and VisionFive RISC-V boards, generate SBOMs ready for EU CRA and U.S. EO 14028 reporting, speed up iteration with QEMU, and lead embedded Linux projects with confidence.

Who this book is for

This book is for embedded Linux developers, integrators, and engineering leads who want to ship dependable products with the Yocto Project. If you build embedded Linux for a living, or you're tired of fragile build scripts and one-off Linux distributions, this book is your production playbook. You'll get the most value if you're comfortable with Git, the Linux command line, cross-compilation, and shell scripting. No prior Yocto Project experience is required. Hardware hackers graduating from prototypes to maintainable, reproducible products will feel right at home.
