Won't matter for this design, you can safely ignore the warning.
It comes because you did not define any timing constraints on any of the I/Os, so Quartus is warning you of that. It will go ahead anyway and map the logic to the device, but it won't try very hard to improve the timing, since you provided no constraints. Most likely it is way faster than what you can do with your manual switches anyway.

Thanks for the feedback.
I still can't get a successful flash. The board does flash a light when it starts to program, then it immediately fails. I thought maybe it was the missing the constraints file for the board, but I added that and it didn't correct the problem.
Any advice for getting the board to program?
