    Data transfer between FPGA over USB interface to processor (Host USB)

    dpandya9488_1438821

      Hi,

         

      Please refer the attached representation. I have implemented an USB PHY using Cypress FX2LP CY7C68014A USB Controller between FPGA and processor. Processor has an USB host.

         

      On a command received from processor (over USB), FPGA should send a stream of data back (over USB).

         

      I have developed firmware to transfer data from USB controller input (D+/D-)  to FPGA (over 8 bit parallel) , but how should I transfer data recieved by USB Controller (FX2LP) from FPGA (8 bit parallel) to processor (over USB, D+/D-) over USB.

         

      Can someone help me with this..

         

      Thanks in advance,

         

      Dhara.
