Ah, you knew the issue exactly, I did not even compile it.  Now after compiling, I was able to link and load it onto the board properly.

It is nice to see the solution come from a pure Ada perspective as well.  I am very early in learning to write embedded firmware, and any software in general, so I greatly appreciate your help.
