Just to help you all decide about how many AX5043 Pi boards need to be built:
I just heard from Alan. He only had two boards in the end. He is sending one to Jim and one to me today. I already have one board, so I may try to ensure that I can run two 5043s from a single TMS570 at some point, but if someone can use a 5043 before any can be built, let me know.
