The IIO oscilloscope does not have a list of plot channels.

Hi,

I want to check the output spectrum waveform of the ADRV9008-1 using an IIO oscilloscope.

My test environment is the ZC706 + ADRV9008-1.

When I boot zc706 I have adrv9009-phy in /dev, and IIO oscilloscopes also load the adrv9009-phy plugin properly.

When I change the signal strength input to Rx1 and Rx2, the RSSI changes in the receive chain of the IIO oscilloscope.

There is no problem at the status of JESD204.

ADRV9008-1 is operating normally, why is there nothing in the Plot Channel list?

and When running under Linux, it attaches the log of the terminal.

    can you run iio_info and post here?
