Embedded Linux Essentials Handbook

Get a complete overview of Embedded Linux, from the Kernel to Qt, and work through hands-on examples to build, simulate, and deploy real-world systems on Raspberry Pi 5Key FeaturesLearn by coding with real examples on Raspberry Pi 5 and QEMU (for those who don't have access to hardware)Get introduced to Rust and see how it fits within an embedded Linux systemUse Qt, a modern GUI framework, to create applications like a scientific instrument with live temperature sensor dataPurchase of the print or Kindle book includes a free PDF eBookBook DescriptionEmbedded Linux now powers everything from IoT devices to industrial systems, making it essential for embedded software engineers to be skilled at customizing, deploying, and developing for these platforms. 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.What you will learnUnderstand the architecture, components, and use cases of embedded Linux systemsDebug and secure the Linux kernel and modern tools like eBPFBuild custom embedded Linux images using Yocto and BuildrootSimulate custom embedded Linux images using QEMUFlash, boot, and validate images on Raspberry Pi hardwareDevelop, deploy, and debug applications using C/C++, Python, and QtAutomate image and application builds with Docker and GitHub ActionsApply your skills through hands-on projects such as web interfaces and complex GUI-based instrumentsWho this book is forThis book is for beginner to intermediate embedded systems engineers, software developers, and enthusiasts seeking hands-on experience with Embedded Linux. It s ideal for those eager to build real-world projects using accessible hardware like the Raspberry Pi. To get the most out of this book, you should understand basic embedded systems concepts, be comfortable writing simple programs in C, C++, or Python, and feel confident using the terminal and working with basic hardware.]]>
