RFDC version mismatch with pynq drivers

Support
1

Hello

I am using vivado 2020.1 in order to create a rfdc overlay
and pynq image version 2.5

but i get that error after trying to download the overlay :

/usr/local/lib/python3.6/dist-packages/pynq/overlay.py:83: UserWarning: IP usp_rf_data_converter_0 is of type xilinx.com:ip:usp_rf_data_converter:2.3 and driver found for [xilinx.com:ip:usp_rf_data_converter:2.1]. Use ignore_version=True to use this driver. warnings.warn(message, UserWarning)

Thanks
Shalom

The PYNQ 2.5 image is tested with Vivado 2019.1. As you are using a different version of Vivado, you are using a different version of the RF IP. If there have been major changes, the IP may not work with the existing PYNQ driver.
You can go back to 2019.1, or try use ignore_version=True if you want to try with the existing driver.

Thank you
After applying your suggestion its work and
I call the following :

ol?
then get the
IP Blocks
usp_rf_data_converter_0 : xrfdc.RFdc

So after trying to use the following :

ol.usp_rf_data_converter_0?
i get this error :
Object ol.usp_rf_data_converter_0 not found.

do you have any idea why ? is it because mismatch on driver version?

Thanks
Shalom

Here is the error when i call the following:

ol.usp_rf_data_converter_0

The PYNQ interrupt infrastructure expects all interrupts in IP that you want to use be connected to an AXI interrupt controller - the exact details are here.

OK i will check that , thank you !
