Hi, we have used fft ip in our design initial for some sample the fft is worki fine.
after some time fft is not giving any output or requesting any data what may be the wrong.
my configurations: 32 point fft.

There are a couple of reasons why the FFT IP core might hang: 1) Violating the AXI stream protocol, 2) Holding M_AXIS_TREADY low, and 3) Not setting TLAST at the end of an FFT. This last might happen if you lose count of values going in and out of the FFT
