I'm at last step of the No OS quick start guide for the FMCOMMS1 board.
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
Is there something else I might be missing? Thanks!
