Hi All,
I am trying to use McBSP1 has an inter-processor data link between two OMAP3530. I can write and read data on the buffers in digital loopback no problems; also I can see the data coming out of the interface on a digital scope. What I can not get is my receiver side to see the data.
My basic configuration is has follow, the McBSP1 on each CPU is configured has MASTER for Tx and a SLAVE for Rx.
I now I am missing something very basic [:)]
Here are registers configuration:
