You need to download some reference manuals and set up your Beagle with some extra files. Here's what to do.

Download Reference Manuals

There are two important hardware reference manuals you need to have, the System Reference Manual (SRM) and the Technical Reference Manual (TRM) for the ARM processor. Here's where to find them.

  1. The official SRM is kept here on github. Here you will find a pdf file with the SRM. Download it.
  2. Finding the TRM if for the am335x and is on TI's site.

Keep both of these in an easy to find place, we'll reference them now and then.

Set Up Git

Many of the following exercises require some extra files on the BeagleBoard which you should have loaded on your host computer eariler. These files are stored in a git repository. We'll learn more about using git later. Here I'll just show you how to get the files.

Get the Files

It only takes one command to pull down all the files.

bone$ git clone https://github.com/MarkAYoder/BeagleBoard-exercises.git exercises --depth=1

(The whole repo is some 550M. Using --depth=1 you only get the recent history and it only takes 190M.)

This will take a while since it's getting all the course files, including pdf files of the course PowerPoint. You only have to clone once for each computer. I suggest you do the same on your host computer if you have done so already.

host$ git clone https://github.com/MarkAYoder/BeagleBoard-exercises.git exercises --depth=1

Now take a look at what you got.

bone$ cd exercises
bone$ ls
bone$ cd pptx
bone$ ls

Later exercises will tell you which files to use from here.

If it's been a while since you did the clone it's a good idea to do a pull. This will make sure all the files are up to date.

bone$ git pull

P8 and P9 Header Files

The BeagleBone Black has two headers, P8 and P9, that have lots of IO. There are two pdf files that have lots of information about the headers in this git repository. Here's how to get them

host$ git clone git://github.com/derekmolloy/boneDeviceTree.git
host$ cd boneDeviceTree/docs
host$ ls
BeagleboneBlackP8HeaderTable.pdf  BeagleboneBlackP9HeaderTable.pdf

Put these where you can find them again.
