ZED + FMCOMMS1 No OS help

Hi,

 

I'm at last step of the No OS quick start guide for the FMCOMMS1 board.

http://wiki.analog.com/resources/eval/user-guides/ad-fmcomms1-ebz/quickstart/no_os_microblaze

 

Everything's worked well until try to display the captured sine wave by Vivado Analyzer. The guide says to create a waveform using 14 bits of axi_ad9643_dma_ddata, but I think it should be 16 for this case (I've tried both anyways). The waveform has all this extra modulation on top the sine wave. I saw another thread where someone recommending changing the trigger settings, and I tried that, but it did not help

 

Not Sinus - FMCOMMS1 with ZedBoard running without OS

 

Is there something else I might be missing? Thanks!
