Linux/66AK2E05: K2E EVM unable to acees netcp pktdma from dsp core

Part Number: 66AK2E05

Tool/software: Linux

We performed set of experiment to understand pktdma of netcp behavior and its configuration.

1. We found the in case of K2H  , no boot mode, hello words example is running fine which send the  "hello word " to some other pc and receive back by running the window application which send back what it received.

   We found here that  netcp packet dma RX and TX channel are able to enabled by cppi module.

2. Same is the case of when running linux in arm , BUT here on loading hello world application in dsp, ethernet link is accessible only from dsp.


Now in case of K2E.

1a, Same hello world application loaded  in dsp when  EVM is configured in no boot mode, here  We found here that  netcp packet dma RX and TX channel are  always  found in disable state .
  This behavior  is not understandable .

  Please let us know how  NETCP'S  pkt dma rx and tx  channel always get disable , even on forcefully trying to enable it in no boot mode??
  Something missing??
