Mastering Embedded Linux Programming – Second Edition
This is the code repository for Mastering Embedded Linux Programming — Second Edition, published by Packt. It contains all the supporting project files necessary to work through the book from start to finish.
Embedded Linux is widely used and there’s a need of selection, organization, and presentation of embedded linux.
Mastering Embedded Linux Programming 2nd edition takes you through the product cycle and gives you an in-depth description of the components and options that are available at each stage.The aim of this book is to help you create efficient and secure embedded devices using Linux. You will begin by learning about tool chains, boot loaders, the Linux kernel, and how to configure a root file system to create a basic working device which will be followed by using Buildroot and Yocto to speed up and simplify the development process .Key topics include basic system set-up, toolchains, accessing hardware at a low-level, robustness, real-time behavior and security.Its purpose is to make you aware how to construct an embedded Linux using open source projects to produce a robust and reliable system by understanding about Linux 4.9 Yocto’s Pyro 2.3 along with the latest Buildroot.
By the end of the book , you will be able to derive a wide choice of solutions to solve a particular problem.
Instructions and Navigation
All of the code is organized into folders. For example, Chapter04.
The code will look like the following:
At the end of the ROM code phase, the next stage bootloader is present in on-chip memory and the ROM code jumps to the beginning of that code.

Key Features Build and configure reliable embedded Linux devices Learn to build robust systems with the most updated version of Linux 4.16 and Yocto Project 2.5 (Sumo) Practical guide to build efficient embedded devices on Linux Book Description
Linux is a core technology in the implementation of the inter-connected world of the Internet of Things. Embedded Linux runs on a variety of devices from desktops and servers to WiFi routers to Linux powered rifles.
This book will focus on building and configuring robust embedded Linux devices. The comprehensive guide shows you the technologies and techniques required to build Linux into embedded systems. You’ll see how to create each of the elements from scratch, and how to automate the process using Buildroot and the Yocto Project. You will also learn to implement an effective storage strategy for flash memory chips, and how to install updates to the device remotely once it is deployed. You’ll also get to know the key aspects of writing code for embedded Linux, such as how to access hardware from applications, the implications of writing multi-threaded code, and techniques to manage memory in an efficient way. Lastly, this book will show you how to debug your code, both in applications and kernel-level, and how to profile the system so that you can look out for performance bottlenecks.
By the end of this book, you will have a complete understanding required to create a successful embedded Linux system.
What you will learn Evaluate the board support packages offered by most manufacturers of a system. Explore Buildroot and the Yocto project to create embedded Linux systems. Update IoT devices in the field without compromising security Install Buildroot and use it to build images for the QEMU and BeagleBone Black targets Learn to install Yocto Project and build basic images for QEMU and BeagleBone Black.

If you are an engineer who wishes to understand and use Linux in embedded devices, this book is for you. It is also for Linux developers and system programmers who are familiar with embedded systems and want to learn and program the best in class devices.
Mastering Embedded Linux Programming — Second Edition: Unleash the full potential of Embedded Linux with Linux 4.9 and Yocto Project 2.2
Embedded Linux runs many of the devices we use every day, from smart TVs to WiFi routers, test equipment to industrial controllers — all of them have Linux at their heart. Linux is a core technology in the implementation of the inter-connected world of the Internet of Things.
The comprehensive guide shows you the technologies and techniques required to build Linux into embedded systems. You will begin by learning about the fundamental elements that underpin all embedded Linux projects: the toolchain, the bootloader, the kernel, and the root filesystem. You’ll see how to create each of these elements from scratch, and how to automate the process using Buildroot and the Yocto Project.
Moving on, you’ll find out how to implement an effective storage strategy for flash memory chips, and how to install updates to the device remotely once it is deployed. You’ll also get to know the key aspects of writing code for embedded Linux, such as how to access hardware from applications, the implications of writing multi-threaded code, and techniques to manage memory in an efficient way. The final chapters show you how to debug your code, both in applications and in the Linux kernel, and how to profile the system so that you can look out for performance bottlenecks.
By the end of the book, you will have a complete overview of the steps required to create a successful embedded Linux system.

Mastering Embedded Linux Programming. Chris Simmonds
Linux is an extremely flexible and powerful operating system and I suspect we’ve yet to truly see it used to full advantage in the embedded world.
One possible reason is that there are many different facets to it and the learning curves can be steep and time consuming. Its possible to figure your way own through the world of Embedded Linux, as I myself have done over the past decade, however I am pleased to see people like Chris putting together books like this which give people a good grounding on many useful topics. I certainly could have used a guide like this back when I started!
I obviously have a personal bias to the Yocto Project, it being my major contribution and attempt to make a difference to the Embedded Linux world. One of its core objectives is to try and make things easier for people building Embedded Linux systems.
We’ve had some successes; there are also areas we know work is still needed. We’re continually trying to simplify barriers to entry and let more people get involved, make the technology more accessible and encourage adoption. In writing this book, Chris is supporting the same objectives.
I hope you enjoy the book, enjoy Linux and that ultimately that we might see you becoming a part of the vibrant open source communities that make up many of the components you’re about to learn about.
