Mastering Embedded Linux Programming - Third Edition

• 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. 
• Reduce the power budget of devices to make batteries last longer
• Interact with the hardware without having to write kernel device drivers

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.

• 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)
