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.

What is DevOps?

Since its inception in 2009, the DevOps movement has taken the software industry by storm. Patrick Debois coined the term DevOps after seeing the 2009 Velocity Conference presentation 10 Deploys per Day. Patrick is one of the four co-authors of The DevOps Handbook along with Gene Kim, Jez Humble, and John Willis. The DevOps Handbook was first published in 2016 and codifies the principles of the movement. These ideas originate from the Lean manufacturing and Agile software development communities. DevOps practices are closely aligned with Agile methodologies like Scrum and Kanban. The goal of all these approaches is always to ship quality products to customers faster.

DevOps strives to integrate the development and operations teams within an organization. Historically, the people who operate software at a company are separate from the people who develop that same software. Sometimes there is a dedicated team of system administrators (IT) responsible for provisioning...
