using the FFT block

HELP !!!!!!!!!!!! 

 

I am using the fft megacore function in streaming mode. I have set the reset_n pin and sink valid at the same time. In the next clock cycle i assert the sink_sop for one clock cycle(It is only active for one clock cycle). At the point where I assert the sin_sop, that is where the FFT block asserts the sink_ready. And I do not get a source_error, but there is no output. It is zero all the time. My sin_imag is zero. That is I am only inputing the real signal.
