How to set the gpio of npm1300 as an interrupt event to notify the host?

[duxinglang]

I am using NPM1300 as a power management unit for a client project. According to its specifications, it has 5 GPIO pins that can be set as interrupt signal pins to notify the host of certain events. However, after setting it according to the specifications, I cannot obtain interrupts from the GPIO pins normally. When I operate the USB cable, I almost cannot receive interrupt signals, and occasional changes in the voltage levels of several GPIO pins also exceed my expectations, As shown in the screenshot, is my setting method incorrect?

Hello Biao, just letting you know we are working on this.

Okay, I'm waiting for your good news.

Hi Biao.

Is the PMIC also connected to a battery during this test?

If you are experimenting with interrupts, I suggest using either a GPIO or SHP/HLD in the first instance as that will isolate any issues related to powering up the device that may cause confusion.

There is a Zephyr based example using interrupts here that may be useful:
