    Leader and Trailer Packet

    user_136061072

      Hello,

         

      I use the slavefifosync example to stream data from the GPIF to a Bulk_IN endpoint.

         

      The streamed data has to look like follows:

         

      leader-packet ; GPIF-data-packets ; trailer-packet

         

      leader-packet and trailer-packet must use one transfer each.

         

      leader-packet and trailer-packet containing only status information.

         

      So the header/footer mechanism of the dma-channel will not work for me.

         

      GPIF-data can be multiblte transfers.

         

       

         

      How can I add the leader-packet/trailer-packet to a   CY_U3P_DMA_TYPE_MANUAL channel ?

         

      How can i achieve such a streaming layout?

         

      Best regards
