Check the "board_spec.xml" file in your BSP for a set of lines like the following: 

  <channels>
    <interface name="board" port="host_to_dev"  type="streamsource" width="256" chan_id="host_to_dev"/>
    <interface name="board" port="dev_to_host"  type="streamsink" width="256" chan_id="dev_to_host"/>
  </channels>

If these lines do not exist, your BSP does not support host channels (which is the most likely case).
