Hi @hazhuzhu,

Would you mind trying to upgrade your version of Pynq-Metadata to see if it solves the issue. Can you run the following on your board:

```auto
python3 -m pip uninstall pynqmetadata
python3 -m pip cache purge
python3 -m pip install pynqmetadata

```

You might need to reset your board after doing the upgrade just to be sure.

Let me know how you get on!

Thanks,  
Shane
