Chapter 1. Installing the Developing System

In this first chapter, after a short introduction to some common terms of the embedded programming used in this book, we'll give you a brief overview of BeagleBone Black's hardware features, how to use the BeagleBone Black's on-board operating system, and how to (re)install and set up a complete developing system based on the Debian distribution, starting from zero. At the end of this chapter, we will give you some hints on how to install a complete host system based on Ubuntu.
