ADRV9002 + GNU Radio + ZCU102


I am trying to use ADRV9002 as a iio source block in GNU radio(3.7.8 ) on the ZCU102 board using B0_pre_release image. 

I am remote ssh to the ZCU102/ADRV9002 on a separate windows PC and trying to run the GNU radio locally on the ZCU102 (for now). 

In the linux command line on the ZCU102, I am able to open gnuradio-companion and insert a blank "IIO Device Source" in place of the FMMCOM source used in the /home/analog/Desktop/gnuradio-examples/fmradiio.

I am attempting to fill out the parameters correctly for the IIO Device Source block to get the ADRV9002 set up as a source and right now have the following:

ID: iio_device_source_0

Hostname: localhost

Device Name/ID: axi-adrv9002-core-tdd-lpc

PHY Device Name/ID: adrv9002-phy

Channels: ['in_voltage0_','out_voltage1_']

Buffer Size: 0x8000

Decimation: 1

Parameters []

I am getting the following error when I try to execute my GNU radio GUI:

Generating: "/home/analog/Desktop/gnuradio-examples/"Generating: "/home/analog/Desktop/gnuradio-examples/"

Additionally, what is the difference between the "PHY Device Name/ID: adrv9002-phy" and the "Device Name/ID: axi-adrv9002-core-tdd-lpc" and why are both needed?
