McBSP ping-pong double-buffering on C6657 EVM

Hello All,

I'm trying to understand how to use the MCSDK McBSP driver for the C6657 EVM so that it would operate on a continuous basis in double-buffer (ping-pong) mode.

I was able to implement the McBSP digital loopback demo but, in terms of using the driver in a continuous fashion using double-buffering, I feel pretty much helpless. It's unfortunate that such a complex and complete piece of software doesn't come with enough documentation and examples to be able to use it for such a fundamental mode of operation.

I've read the series of posts talking about this in this forum, but my impression is that this question hasn't really been answered. Did I miss something? Has anybody been able to use the McBSP driver to implement double-buffering on the C6657 EVM? Is there some example code that could be shared?

Any help would be greatly be appreciated.
