Hi all,
I am working on cypress FX3. I need to pass data from host to FPGA through cypress. I am stuck with DMA buffer and endpoint creation concept.
1.How the data in exchange between one end point to another endpoint?
2. is DMA buffer needed for USB data read ? is it possible to read USB data without DMA.
Solved! Go to Solution.

- To do that you need to create a DMA channel between USB Producer Socket and PIB Consumer Socket.
Please refer to following App Note where it is implemented:
