    GPIF Does not send data to peripheral

    fpgair_2023366

      hi every body.

         

      I want to send data from host to FPGA in with CY7C68013A in GPIF mode.

         

      So I've Design a simple waveform like this :

         

      https://ufile.io/87df21

         

      and also I've written and firmware that with receiving vendor command 0xb2 goes to GPIF mode and set fifo write transaction for 277 kbyte.but it seems that the firmware does not trig GPIF waveform.

         

      for testing the project first i Was sending the 0xb2 command with control center and then sending my data in endpoint2(bulk out endpoint, quad buffer) but i am unable to send more than 4 packet...

         

      what is wrong?

         

      here is main code:
