Custom Overlay fails on "hdmi_in.configure()" with PYNQ-ZU

I recreate the base_overlay on vivado and delete what I don’t need for my project.

The problem I encountered after successfully loading the bitstream on the board

Below is the screenshot of the problem and the block design

Hi @joshua20000216,

Welcome to the PYNQ community.

There’s a dedicated driver for the base overlay that configures some clocks.

So I need to load the ‘base.py’ on the board too?

btw, thank you for your quick reply.
I am the beginner on FPGA, this pynq stuff is my college project
I do my best for searching the imformation on internet, so if my question is stupid, I am sorry about that.

No, the configuration for those clocks will be erased when you download you custom overlay.

You need to configure the IP and clocks as the _init_clocks function is doing.
