can't set EDMA registers

Hello,

I'm trying to setup EDMA in my program, starting first with a simple timer trigger memory transfer (eventually the edma will service the mcasp).  But I can't change any EDMA registers, either programatically or manually.  I should have enabled the module in the PSC properly (TPCC0 and TPTC0).

For instance, if I set a breakpoint in my program where the edma is configured, and manually try to change the EDMA registers, such as ECR, etc, they just remain 0, no matter what value I enter.

Any advice on where to look would be appreciated.

Robert
