Mastering Embedded Linux Development

Mastering Embedded Linux Development

By: Frank Vasquez, Mr. Chris Simmonds

Overview of this book

Mastering Embedded Linux Development' is designed to be both a learning resource and a reference for your embedded Linux projects. The book starts by breaking down 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 in an efficient way. The final chapters demonstrate how to debug your code, whether it resides in user space or in the Linux kernel itself. In addition to 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. By the end of this book, you will be able to create efficient and secure embedded devices with Linux that will delight your users.

Provisioning your development environment

I have only used open source software for both the development tools and the target OS/applications. I assume you will be using Linux on your development system.

I tested all the host commands using Ubuntu 24.04 LTS, so I recommend using that version throughout the book to prevent any unexpected problems.

Besides Ubuntu, The Yocto Project only supports a select few Linux distributions: Fedora, Debian, openSUSE, AlmaLinux, and Rocky. If you absolutely cannot use Ubuntu, then make sure to choose one of those supported distros for The Yocto Project exercises.
