CHAPTER 2 The BeagleBone Black Software

In this chapter, you are introduced to the Linux operating system and software tools that can be used with the BeagleBone. This chapter aims to ensure that you can connect to your BeagleBone and control it. By the end of this chapter you should be able to “blink” a system LED having followed a step‐by‐step guide that demonstrates how you can use Linux shell commands in a Linux terminal window. In this chapter, you are also introduced to a library of BeagleBone functions, called BoneScript, which can be used with Node.js and the Cloud9 integrated development environment to build code that flashes the same system LED.

Equipment Required for This Chapter:

  • BeagleBone Black board
  • Supplied USB cable (USB A male to mini‐USB A male)
  • Micro‐SD card (4 GB or greater; Class 10+) (optional)
  • Network infrastructure and cabling (optional)
