  Now that I have the AD9371 devices up and running, I want to write some apps to send data to the devices.  I have built the libiio example program ad9371-iiostream.   When I run it on my ZCU102 with the AD9371, it fails at device_check_ready when trying to refill the RX buffer (returns error code -110 = -ETIMEDOUT).  I checked my axi-ad9371-rx-hpc, and I could read the parameters and write to some of them.  What is device_check_ready looking for?  Is this error related to sampling frequency or other device settings that I need to tweak?
