Hi:

      I am using Cypress USB 3.0(CYUSB3KIT-003,CYUSB3ACC-005 kit) as slave fifo to connect with FPGA board.

      Till now, I have successfully made data received from FPGA on USB control center. But When running BULK OUT, that is, sending data from USB to FPGA, FPGA failed to received the data.

      The related results showned below.

      Figure-1 show Streamer failed to transfered data. Figure-2 show FPGA trigger signal flagc_IBUF and flagd_IBUF always remaid 0, that is, flagc and flagd signals were not be sent from firmware.

      Can you help us figure out the reason? We all appeciate you support.

Hi,

If you want to implement slaveFIFO application please take AN 65974 as your reference. Please try with it once.

Here is the link to that AN:

Hi,

Are you able to see some success in the starting of the transfer?

Are you using custom board or the development kits?

Thanks & Regards

Hello, Abga

Download firmware "SlaveFifoSync.img“ to FX3 RAM, start "Streamer" interface and transmitting data, then the data should be received on FPGA?

But the desired result didn't appear. Whether has the firmware "SlaveFifoSync.img“ any question or some paramter should be configured rightly and then FPGA can received the data from FX3.
