    GPIF loopback

    nassim.corteggiani_1649741

      Hi,

         

      How can I do a simple GPIF loopback ?

         

      I want to stream data from my host to the FX3 board that send it to the GPIF Databus and send back the databus value to my host.

         

      I can send data to the databus but I cannot read the databus just after... I didn't receive anything ...

         

      I use the CY_U3P_UIB_SOCKET_PROD_1 -> CY_U3P_PIB_SOCKET_0 and  CY_U3P_PIB_SOCKET_4 -> CY_U3P_UIB_SOCKET_CONS_1 channels.

         

      In my state machine I just do a DR_DATA and IN_DATA both on the thread0.

         

      But I never receive data back....

         

      Any advice please ?
