Mastering Embedded Linux Programming

Chapter 1: Starting Out

You are about to begin working on your next project, and this time it is going to be running Linux. What should you think about before you put finger to keyboard? Let's begin with a high-level look at embedded Linux and see why it is popular, what are the implications of open source licenses, and what kind of hardware you will need to run Linux.

Linux first became a viable choice for embedded devices around 1999. That was when Axis (https://www.axis.com) released their first Linux-powered network camera and TiVo (https://business.tivo.com) their first Digital Video Recorder (DVR). Since 1999, Linux has become ever more popular, to the point that today it is the operating system of choice for many classes of product. In 2021, there were over two billion devices running Linux. That includes a large number of smartphones running Android, which uses a Linux kernel, and hundreds of millions of set-top boxes, smart TVs, and Wi-Fi routers, not to mention a very diverse range of devices such as vehicle diagnostics, weighing scales, industrial devices, and medical monitoring units that ship in smaller volumes.

In this chapter, we will cover the following topics:

  • Choosing Linux
  • When not to choose Linux
  • Meeting the players
  • Moving through the project life cycle
  • Navigating open source
  • Selecting hardware for embedded Linux
  • Obtaining the hardware for this book
  • Provisioning your development environment

Key benefits

  • Learn how to develop and configure robust embedded Linux devices
  • Explore the new features of Linux 5.4 and the Yocto Project 3.1 (Dunfell)
  • Discover different ways to debug and profile your code in both user space and the Linux kernel

Description

If you’re looking for a book that will demystify embedded Linux, then you’ve come to the right place. Mastering Embedded Linux Programming is a fully comprehensive guide that can serve both as means to learn new things or as a handy reference. The first few chapters of this book will break down the fundamental elements that underpin all embedded Linux projects: the toolchain, the bootloader, the kernel, and the root filesystem. After that, you will learn how to create each of these elements from scratch and automate the process using Buildroot and the Yocto Project. As you progress, the book will show you how to implement an effective storage strategy for flash memory chips and install updates to a device remotely once it’s deployed. You’ll also learn about the key aspects of writing code for embedded Linux, such as how to access hardware from apps, the implications of writing multi-threaded code, and techniques to manage memory in an efficient way. The final chapters demonstrate how to debug your code, whether it resides in apps or in the Linux kernel itself. You’ll also cover 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 Linux book, you’ll be able to create efficient and secure embedded devices using Linux.

Who is this book for?

If you’re a systems software engineer or system administrator who wants to learn how to implement Linux on embedded devices, then this book is for you. It's also aimed at embedded systems engineers accustomed to programming for low-power microcontrollers, who can use this book to help make the leap to high-speed systems on chips that can run Linux. Anyone who develops hardware that needs to run Linux will find something useful in this book – but before you get started, you'll need a solid grasp on POSIX standard, C programming, and shell scripting.

What you will learn

  • Use Buildroot and the Yocto Project to create embedded Linux systems
  • Troubleshoot BitBake build failures and streamline your Yocto development workflow
  • Update IoT devices securely in the field using Mender or balena
  • Prototype peripheral additions by reading schematics, modifying device trees, soldering breakout boards, and probing pins with a logic analyzer
  • Interact with hardware without having to write kernel device drivers
  • Divide your system up into services supervised by BusyBox runit
  • Debug devices remotely using GDB and measure the performance of systems using tools such as perf, ftrace, eBPF, and Callgrind

Caveat - I work for a software company that is mentioned in the book, which is how I became acquainted with one of the authors. So I probably have some biases.This book could easily be a college textbook. In a good way - a textbook that reads well and that you keep as a handy reference. The book covers a wide gamut - from bootloaders to kernels to developing with Yocto to profiling & tracing. It's a good progression. It definitely demystified some concepts for me, especially related to kernels. Even though I skimmed some chapters, later chapters still made sense - a sign of good writing.So who is this book for? IMHO, it's for people that are familiar with at least a few of the concepts (chapters) in the book. But want to learn the concepts & details in the other chapters, and generally go deeper. And importantly, it's the kind of book where you can read it as you need it e.g. read a few relevant chapter when you have a related work project coming up.
