Embedded Linux Essentials Handbook: Build embedded Linux systems and real-world apps with Yocto, Buildroot, and Rpi

Abstract

This hands-on guide walks you through the core concepts of Embedded Linux using practical, real-world examples on Raspberry Pi 4 and 5. For those without access to hardware, it also demonstrates how to simulate embedded Linux systems using QEMU. This book contains code samples that you can follow along and build three real-world projects: a Python web-based dashboard that retrieves and displays data from a temperature sensor and two GUI applications demonstrating how to use the Qt framework on Embedded Linux using two different development paradigms. You’ll also step into advanced territory with Linux kernel debugging techniques and discover how to harness eBPF, building the experience employers want and the confidence to tackle complex embedded challenges. By the end of this book, you'll have a solid grasp of Embedded Linux development and the skills to build and deploy production-ready, modern embedded applications.
