PYNQ does not support the interrupts to be connected like that. You need an interrupt controller

[https://pynq.readthedocs.io/en/v2.6.1/overlay\_design\_methodology/pspl\_interface.html#interrupt](https://pynq.readthedocs.io/en/v2.6.1/overlay_design_methodology/pspl_interface.html#interrupt)

Something like this
