    How does FPGA communicate with CYUSB3KIT-003 for protocols?

    kelvin.xu_1593951

      I am using CYUSB3KIT-003 and the CYUSB3ACC-005 to work with Xilinx ZC702 to stream video into PC. 

         

      I realize the FPGA serves as a master role in the GPIF port. 

         

      I am reading the AN65974 but how does the GPIF communicate to the FPGA how many bytes the PC has or wants? 

         

      How do the control packets get into the FPGA?
