Can't using FMCOMMS11 with iio-osc

Hi,

Recently we got a FMCOMMS11 from arrow and we quickly setup the zc706 FPGA environment with related image file (the latest one).

but we just can't received RX file on the osc plot (iio_version: 0.21).

here's our osc screenshot:

As you can see the terminal keep showing "timeout" while fetching data from ADC.

Also the dmesg shows the linux can't get DAC clock while loading the driver

  

Thanks,

Justin
