Try using this instead of button_dev:

#define BUTTON_PORT DEVICE_DT_GET(DT_GPIO_CTLR(DT_NODELABEL(button0), gpios))

I noticed it at the beginning and added it to the end of the overlay.

P1.13 is by default set to the MOSI pin of spi3 for the nrf52840dk. If your custom board is uses the nrf52840dk board files, you will have to disable spi3 or change the pin configuration of spi3.

In that case, try with this in your overlay file:

&spi3 {
    status = "disabled";
};

Customized nRF52840 board.

Please check my question again.
1. The same code, just modified the overlay, why the pin of gpio0 can work but the pin of gpio1 can't?
2. How the pin of gpio1 is used as an external interrupt pin in NCS?

Hi,

Which board are you using, and have you made any changes in the board files or through an overlay?
