I decided I had gotten a little ahead of myself as my application had stated that I would setup and run the applicable demos. So, I've restarted at the link given by doctorcdf on the roadtest discussion page:
GettingStarted_a5d4_xplained < Linux4SAM < TWiki
I also found a "datasheet" for the SAMA5D4 Xplained Ultra board in the following location: http://www.farnell.com/datasheets/1878977.pdf
By the way, the first step of my test plan is:
Setting it up using the quick start guide, user's guide, and online documentation.
As it is there has been no real "quick start guide". The card that came inside the box simply gave key features and regulatory information and provided a link to the website. The Farnell website lists three documents available for the board, however two of the links produce the exact same document (the user's guide) and the other link goes to a page for a DC Motor Control shield.
