Data from FX3 to FPGA is repeating continuously

Hi,

I'm Transfering data from FX3 to FPGA via GPIF II interface.I'm able to transfer only 12 bytes of data through control center and only 9th byte is showing in waveform

The data i'm getting on FPGA side is repeating as shown in below image.

Regards,

Aswini

Hello Aswini,

Please program the FX3 with the attached firmware and try to send 512 bytes from the Control center (for USB 2.0) or 1024 bytes for (USB 3.0) and let me know the results.

I have checked it with USB 2.0 at my end and the results are attached.

PCLK - 99MHZ (0.010 us)

SLRD asserted for - 2.56 us - each clock edge 2 bytes data is transferred (as the GPIF interface is 2 bytes) - 512 bytes written from usb > FPGA

Similarly, results are attached for for transferring 32, 128, 256 bytes from USB to FPGA (USB 2.0)

Please check the firmware at your end and let me know the results

Regards,

Rashi
