This chapter gave us a very short introduction to Linux and our board. We talked a bit about the hardware, how to connect it to your host machine, how to login to the Linux system via SSH, and some very basic commands to perform operations on a Linux system.
You saw how files and folders are represented in the filesystem and how you could modify these permissions. We created our first program and successfully executed it in our target environment. From here on, we will start working on more complicated programs.
In the next chapter, we will connect an LED to our board and control it. Subsequently, chapter by chapter, we will start working through the different areas of our hardware, building up knowledge on how to control different peripheral devices and learning how to communicate with our Beagle remotely over a network.
