Are you struggling to choose between Yocto and Buildroot for your next Embedded Linux project? Do you want to build secure, maintainable, and production-ready devices without spending months piecing together information from scattered documentation, forums, and outdated tutorials?Modern embedded products demand far more than simply building a Linux image. Today's engineers must manage custom hardware platforms, automate build pipelines, implement secure boot, deploy OTA updates, maintain compliance requirements, and support devices throughout years of field operation. Embedded Linux Engineering with Yocto and Buildroot is a practical, hands-on guide designed to help you build commercial-grade Embedded Linux systems using the industry's two most important build frameworks. Rather than focusing on Linux theory, this book teaches the workflows, tools, and engineering practices used by professional teams to develop and maintain real products. Inside this book, you will learn how to:Build custom Embedded Linux systems using both Yocto and BuildrootCompare the strengths, limitations, and ideal use cases of each platformConfigure kernels, root filesystems, BSPs, and Device TreesDevelop and integrate modern C++20 and C++23 applicationsCreate reproducible build environments using Docker, Git, and CI/CD pipelinesImplement secure boot chains, image signing, and runtime verificationDesign robust OTA update systems with rollback protectionGenerate Software Bills of Materials (SBOMs) and manage compliance requirementsDebug, test, benchmark, and optimize Embedded Linux platformsSupport multiple hardware targets, including STM32MP1, NXP i. MX, Rockchip, and RISC-V systemsBuild production-ready edge devices that can be deployed and maintained at scaleThroughout the book, you'll work through practical examples, real engineering workflows, measurable benchmarks, and realistic projects that reflect how Embedded Linux products are developed in commercial environments. Whether you're an embedded software engineer, firmware developer, IoT engineer, robotics developer, systems architect, or technical lead, this book will give you the knowledge and confidence to build, secure, deploy, and maintain professional Embedded Linux products. If you're ready to move beyond basic Linux tutorials and start building Embedded Linux systems the way industry professionals do, this book belongs on your desk.
