Similar error to

Hi Jingyi-li,

I have a few questions that will help me understand the error better.

Are you using the ZCU111 development board?
What version of PYNQ are you using?
Are you using a fresh install of PYNQ?
Finally, try and change init_rf_clks to True when calling the QpskOverlay class. Uninitialized clocks seem to be causing the problem,

Thanks, David.

I too have the same similar even after modifying "ol = QpskOverlay(init_rf_clks=True)".
