metal: error: PLL Lock timeout error in XRFdc_WaitForRestartClr

[Jingyi-li]

Hi, as I was runing the 02_pynq_and_data_converter.ipynb. I got some error. Can you please help me? Thank you very much.

Details are :

metal: error:

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)". `--------------------------------------------------------------------------- RuntimeError Traceback (most recent call last)
