Hi Hemanth , thanks
thern in my test case I'm usung teh SP605 evaluation board and cypres usb3ki-003 , I download the firmware of application AN65974 on USB3 and on FPGA .
For endpoint bulk ut Transgfer in LOOPBACK example is work , baut when I press Trnsfer in I have error code 997
Let me know how can test PRD_EVENT.
Please let me know if your are using the default FX3 firmware and the FPGA code attached with the application note.
Please confirm if you are following the steps mentioned in section 11.5.1 of the application note AN65974
For checking the Producer events, please enable the debug prints in the SlFifoAppThread_Entry function
/* Print the number of buffers received so far from the USB host.
CyU3PDebugPrint (6, "Data tracker: buffers received: %d, buffers sent: %d.\n",
Try doing the data transfers as mentioned in section 11.5.1 of app note and share the UART debug prints
