TAS3251EVM: TAS3251 EVM PBTL mode

Part Number: TAS3251EVM
Other Parts Discussed in Thread: TAS3251

I have two of the TAS3251 EVM boards we have purchased from TI. They must be of two different versions as the PPC 3 software displays slightly different with each board. The first board we obtained just as the TAS3251 was being released. Is it possible there should be a firmware update for this EVM?

Second question: neither board will function in PBTL mode. We have followed the settings as shown by the GUI. No fault lights on the EVM but the PPC 3 seems to be unable to communicate with the board once I place it in PBTL mode.

We have a customer demonstration on Monday so a quick answer would be greatly appreciated.

Thank you.
