Book Description
Harness the power of Linux to create versatile and robust embedded solutions

Key Features
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

Embedded Linux runs many of the devices we use every day. From smart TVs and Wi-Fi routers to test equipment and industrial controllers,all of them have Linux at their heart. The Linux OS is one of the foundational technologies comprising the core of the Internet of Things (IoT).

This book starts by:breaking 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 explains 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.

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
