FX3 slave fifo receive wrong data

[Anonymous]

Hi 
   I  have a problem when i use cyusb3014. I just want to transfer the data that generated by FPGA to PC. But the USB CINTROL CENTER receives the wrong data .

   

   I use the sync slave fifo mode to communicate with the FPGA ,but when i transfer ox4000 and ox4001,the PC receives ox8000 and ox8001. The firmware that i downloaded is  SDK build-in.

       

   Does anyone ever meet this issue ?Is there any explanation to that ?

       

    Thanks for any returns

Hi,

   

This is strange. The only reason I can thnk of this is may be two data lines are interchanged in your schematic. Please check.
