Colin, That would be phenomenally helpful! Do you have a scope?
I'm curious if you see any life on pin 28 of the P9 header with and without a cape. I suspect you will see data with the cape (because the DAC on the cape board is talking to the BBB's processor), but nothing without it. I unfortunately don't have a way to "fake" the cape.
