Written by Frank Vasquez, an embedded Linux expert, this new edition enables you to harness the full potential of Linux to create versatile and robust embedded solutionsAll formats include a free PDF and an invitation to the Embedded System Professionals communityFree with your book: DRM-free PDF version + access to Packt's next-gen Reader*Key FeaturesLearn how to develop and configure reliable embedded Linux devicesDiscover the latest enhancements in Linux 6.6 and the Yocto Project 5.0, codename ScarthgapExplore different ways to debug and profile your code in both user space and the Linux kernelPurchase of the print or Kindle book includes a free PDF eBookBook DescriptionMastering Embedded Linux Development is designed to be both a learning resource and a reference for your embedded Linux projects.In this fourth edition, you'll learn the fundamental elements that underpin all embedded Linux projects: the toolchain, the bootloader, the kernel, and the root filesystem. First, you will download and install a pre-built toolchain. After that, you will cross-compile each of the remaining three elements from scratch and learn to automate the process using Buildroot and the Yocto Project. The book progresses with coverage of over-the-air software updates and rapid prototyping with add-on boards. Two new chapters tackle modern development practices, including Python packaging and deploying containerized applications. These are followed by a chapter on writing multithreaded code and another on techniques to manage memory efficiently. The final chapters demonstrate how to debug your code, whether it resides in user space or in the Linux kernel itself. In addition to GNU debugger (GDB), the book also covers the different tracers and profilers that are available for Linux so that you can quickly pinpoint any performance bottlenecks in your system.*Email sign-up and proof of purchase requiredWhat you will learnCross-compile embedded Linux images with Buildroot and YoctoEnable Wi-Fi and Bluetooth connectivity with a Yocto board support packageUpdate IoT devices securely in the field with Mender or balenaPrototype peripheral additions by connecting add-on boards, reading schematics, and coding test programsDeploy containerized software applications on edge devices with DockerDebug devices remotely using GDB and measure the performance of systems using tools like perf and plyWho this book is forIf you are a systems software engineer or system administrator who wants to learn how to apply Linux to embedded devices, then this book is for you. The book is also for embedded software engineers accustomed to programming low-power microcontrollers and will help them make the leap to a high-speed system-on-chips that can run Linux. Anyone who develops hardware for Linux will find something useful in this book. But before you get started, you will need a solid grasp of the POSIX standard, C programming, and shell scripting.
