I assume you're probably looking at a header. If that's the case you
better double check the schematics and/or Technical Reference Manual to
see what needs to be done to get signals routed to the header. As I
recall there's a pin on the header that needs to be pulled high to bring
signals out to the header.
Alternatively, there's probably an audio codec on-board so you could
probe the pins on the codec.
The McBSP isn't broken -- look harder.

Hi everyone!
I'm new in CCStudio and I have simple question. How I can know what my
McBSP is not broken?
I use DM642EVM. I wrote transmitter, no device connected. I use
oscilloscope to look at pins signal (ALL OF THEM), there is constant 0
(ground). Program continuously transmit data (by poling). There is no
loopback. Fsynk is ON. Transmitter ON.
I will be happy if I will see some moving on oscillogram!
Thanks!
