EBC Getting Exercise Support Materials

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) Beagleboard:BeagleBoneBlack has the official reference materials for the Bone. Take a look through it to see what all is there.  Beagleboard:BeagleBoneBlack takes you to the hardware section. Here you will find a link to a pdf file with the SRM.  Download it.
 * 2) Finding the TRM is a bit trickier. Open the SRM you found in the previous step and find what processor it is using.  (Hint: page 54) You'll find a link to a TI site that has the manual.  Be sure you have the right one, it's some 22M and nearly 5,000 pages long!

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. 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.

Run the following to install git. Be sure to replace my name and email address with yours.

host$ sudo apt install git host$ git config --global user.name "Mark A. Yoder" host$ git config --global user.email Mark.A.Yoder@Rose-Hulman.edu host$ git config --global color.ui true host$ git config --global credential.helper 'cache --timeout=14400'

Now you are ready to use github.

Get the Files
It only takes one command to pull down all the files, but it might take a while since it's getting all the course files, including pdf files of the course PowerPoint.

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

Now that you have the repository on your host, it's easy to copy it to your Bone.

host$ scp -r exercises root@192.168.7.2:.

This does a secure copy (scp) of the repository from your host to the Bone. Now, look around.

host$ cd exercises host$ git checkout -b myBranch

The git checkout lets you make changes to your local file and still be able to access new files that I'll add later. It will be discussed in detail later.

Now take a look at what you got.

host$ ls host$ '''cd pptx

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$ wget https://github.com/derekmolloy/exploringBB/raw/master/chp06/docs/BeagleboneBlackP8HeaderTable.pdf host$ wget https://github.com/derekmolloy/exploringBB/raw/master/chp06/docs/BeagleboneBlackP9HeaderTable.pdf

Put these where you can find them again.
