    FX3 DMA using two p-port sockkets

    jon.bean

       I have setup a DMA AUTO with two p-port sockets 0 and 3. So I have data rx on 0 and tx on 3. The flag on 3 seems to do something I dont expect although it may be correct. Its the dma rdy flag. It seems to go low when the rx starts. There is a dma rdy on the rx too which goes low then high once the rx ends. The tx dma rdy godes high again once the tx ends. Is this corrrect? Also is there anything wrong with this setup? I realsie its a bit strange to send the rx data back out but I want to test something.

         

      Thanks
