Problems with FFT Megacore of Variable Streaming Floating Point Architecture

I've already used with success FFT Megacore of Variable Streaming Fixed Point architecture. Now I'm trying to use Floating Point architecture and it seems to me that the Core is not responding proper...

Ok I'm about to give up. I was wrong about the byte swap, the problem remains.

I've tested my FFT core with other input vectors and it seems to me that it doesn't respond well to some input signals depending on their amplitude and harmonic content.

Is there any condition the input vector of floating point elements must be compliant with for being processed by the FFT core?
