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 ?

Hi,
You can use DR_DATA only on a thread corresponding to a consumer socket and IN_DATA only on a thread corresponding to a producer socket.
So you have to do DR_DATA on Thread 0 and IN_DATA on Thread 4
