Does Altera's FFT Core support backpressure?

Hi, all. 

I'm using FFT Core (Variable streaming, 256 points). I want to control datastream via signal "source_ready", but FFT stall after 2 frames. 

From fft_ug: 

"source_ready ... Asserted by the downstream module if it is able to 

accept data." What I doing wrong?
