Hello, everyone.

I am following [A](https://discuss.pynq.io/t/tutorial-rebuilding-the-pynq-base-overlay-pynq-v2-6/1993) to make a base overlay of ZCU106 board, replacing ZCU104 base with ZCU106.

However, I got the following error.

```auto

```

I’m using Vivado 2020.2 to match 2.7 version.  
I also have a license for the zcu106 board.  
Is there a solution to this problem?

Hi @jooeun526,

This looks like the 2KY22 bug [https://support.xilinx.com/s/article/76960?language=en\_US](https://support.xilinx.com/s/article/76960?language=en_US)

Patch, re-clone the repo and rebuild.
