I am using KCU105 + FMCDAQ2. able to successfully communication over IIO plugin with IIO Oscilloscope and Visual Analog.
I am further interested to do processing on GNURadio as this our requirement . Can you kindly guide me how to use GNURadio with FMCDAQ2.
There are only support for FMCOMMS2/3/4 and not for FMCDAQ2 ( AD9680 / AD9144 ).

You can use the IIO Device Sink/Source blocks to talk to DAQ2.
"PHY Devices" will be blank and the "Device Names/IDs" would be "axi-ad9680-hpc" or "axi-ad9144-hpc".
Channel names will be "voltage0" and "voltage1".
You can lookup this info on the board or remotely using the "iio_info" and "iio_attr" tools.
Thanks for the reply.
I have installed Ubuntu on VirutalBox and followed the procedure as per link below to install GNURadio.
I am able to open the GNURadio GUI and add the source as per your suggestion.
Below are the screen shots of configuration and Error Port not connected.
My Target IP address is 192.168.0.118.
If i ping from Ubuntu VirtualBox the same IP it is able to ping the target.
Your Input on the will be appreciated.
I have attached the GNURadio Project File . Kindly let me know i am still not able to connect to the source.
Awaiting for your reply.

You have to connect a block to a source block, like a scope or DSP block to something.
If you want to learn more about using GNU Radio please check their wiki: https://wiki.gnuradio.org/index.php/Main_Page
We can only provide guidance on how to use our own blocks (gr-iio).
Thanks for the link . I have connected as per some of the samples I exercise provided in the tutorial.
After that as per your suggestion I have connected to QT GUI Tab Widget.Still the ERROR of connecting to port is not resolved. Please find the screen shot of ERROR .

hmmm, ok that definetly a bug. I add a fix to gr-iio.
A workaround for now would be to put an IIO device name in that PHY device string. Try adding 'ad9523-1' for that string field.
Thanks for the reply. Yesterday I filled both fields with axi-ad9680--hpc and it got connected. I will try what you suggested.
I have one more questing to you is it possible to connected to Source IIO one for axi-ad9680--hpc and axi-ad9144--hpc in same project. So that I can route ADC data to DAC ?
Will be awaiting for you feedback.
Yes, this is possible. Just use an IIO Device Sink block for the DACs
Know what you are probably dropping most of the data on the floor since the DACs and ADCs far exceed the bandwidth of Ethernet and the processing power of GNU Radio.
I used IIO Device sink block for DAC. Please find the attached screen shot.
Following is the error
Got the error. I had missed the parameter.
