Hi,

By default, GPIO0/CAM0_PWR# pin (Ball number:G8)- GPIO3,PR00 is configured as GPIO output pin in device tree. I need to change this pin as GPIO interrupt Input pin in device tree and what are the changes, I need to do?

Tried the changes and am facing the problems. Please provide the example for this.

-Thanks.
