    FPGA and PC problem

    @126.com.2

       Hello

         

         I am now using USB3.0 to transfer data. The FPGA control squences is that  at first 500us FPGA do nothing to USB FX3 , and then transfer 128KBytes continuous data  to PC, and then it follow the cycles.

         

        But I found that the 500us void time pend my transfer. If I set the void time to 10us or less. The PC will get data without any problem. So why this problem happened.

         

        I increase the value of the waitforxfer() parameter. But the problem is still there.  thank  you.
