nPM1300EK event callback not firing SPHHLD

Question

Hello, 
 
 I am using the nPM1300EK connected to a nRF54H20 DK over i2c interface. I am trying out the "one button" sample code ( https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/pmic/native/npm1300_one_button/README.html ). 
 The communication is working (I can see the nPM1300's LED flashing) but the event_callback is not triggered when I press the SHPHLD button. I can see that it goes from 5V to 0V, but the callback does not seem to be working. I am using the sample code as it is except from the overlay for the nRF54DK 
 
 What can I try to make it work?

Update:

Try the following overlay: Note that I have wired GPIO 3 on the EK to port 0 pin 5 on the DK

I have tested this on my part and it works. The default nrfx_twim concatenation buffer is too small to handle the I2C activity that happens when an nPM1300 interrupt appears. I had to add the part with

zephyr,concat-buf-size = <40>;

and the host &pmic int pin
