PYNQ: PYTHON PRODUCTIVITY FOR ZYNQ

Overlay loading problem -> ip_dict empty

Hi

I have a question on using PYNQ. Vivado generates the bitstream without errors, but PYNQ can’t read the overlay?

I tried:

$ overlay.ip_dict
resulted in an empty dict, even though the bitstream is > 5MB and was generated using Vivado without errors. So, it should have all the IPs in it.

Any suggestions for what could I be missing or pointers for further debug?

Thanks,

Can you post the Python code you used to instantiate the Overlay?

Did you export the TCL file from Vivado and copy it with the bitstream, or copy the HWH file?

If you did, please post version of PYNQ you are using, and your Tcl file.

You need files (hwh / tcl) more than just the bitstream.
