TAS2781EVM: PPC3 different EVM revision

Let me know what troubleshooting steps to take.  The audio driver seems to be working fine. I just don't see the option to start the driver characterization.

How can I change the title of the main heading?  The main issue is NOT the EVM revision - that issue was noted as not being important.  The main issue is not being able to start driver characterization.

Hello,

Right the error is not EVM revision this note can be ignored. What error is present when you attempt to start characterization?

There is no error when you click on characterization.  It just goes to the screen as shown.  No option to measure speaker.

Please note that if I open a new project (instead of one with manually entered data), or if I delete the characterization data, I still do not get an option to start the characterization. (Always with the board connected). 

Also note that I have no issue playing audio from the PC through the board to a speaker.  Just getting the protection kicking in too early - the assumption is this because the driver characterization is not correct.  Perhaps there is a way to disable driver protection - I know TI has done this for a few people.

Thanks Sydney,

In this posting, Arthur Brown stated that "In the Beta.20 version we obsoleted the learning board and only the EVM is needed."

I'm using 3.3.0 - does this include the elimination of the learning board as mentioned above with 3.2.1 Beta20?
