I programmed FX3 chip with the firmware available with the design note AN65974 with small changes such as

   

commenting #define LOOPBACK_SHRT_ZLP

   

uncommenting #define STREAM_IN_OUT

   

But when i send data through c# application it does not update FLAGC when viewed in ChipScope Pro.

What do you mean by FLAG C not updating. By default FLAG C is used as an Empty Flag for Thread 3 . It will become empty if the external master has read the entire content of the buffer associated. 

   

What is the status of the FLAG when you are checking it?
