Hi Michael,
I've tried going back to an older version of the software that still has the axi-ad9144-hpc iio device and, while there are some waveforms available to load over the data bus, I tried a few and none worked, which I am guessing is related to your reply that the DAQ2 DAC buffer output is currently not supported.
Just so I can be clear, is it accurate to say that, without modifications to the reference design on the ZC706 FPGA, generating anything but the coarsely-spaced CW tones on the DAC is not possible on the FMCDAQ2? Have you also found that for Rev D of the FMCDAQ2 that even with modifications it is not possible?
Thanks,
Mike
