    Leader and Trailer Packet



      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
