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
g.

Hi,
You can use the CyU3PDmaChannelSetupSendBuffer for the same. You may refer MSC example from FX3 SDK to understand the usage of the same.
