nrf54l15: P2.06 not working as normal GPIO

[payalD]

Hi,

I want to configure P2.06 of my custom board nrf54l15 as DI. I have added following configuration in .overlay file

/ {
	gpio_keys {
		compatible = "gpio-leds";
		push_button: push_btn {
			gpios = <&gpio2 6 GPIO_PULL_UP>;
			label = "PUSH_BTN";
		};
	};
};

And configured the pin as input as follows

#define PUSH_BUTTON_NODE	    DT_NODELABEL(push_button)
static struct gpio_dt_spec button = GPIO_DT_SPEC_GET(PUSH_BUTTON_NODE, gpios);
static struct gpio_callback button_cb_data;

gpio_pin_configure_dt(&button, GPIO_INPUT);
gpio_pin_interrupt_configure_dt(&button, GPIO_INT_EDGE_BOTH);
gpio_init_callback(&button_cb_data, on_demand_isr, BIT(button.pin));
gpio_add_callback(button.port, &button_cb_data);

 But I am not getting any interrupts on the pin.

As I read in some posts on devzone, P2.06 is default configured as TRACECLK / SPI.SCK.

Are there any other configurations that need to be added to the .overlay or prj.conf file to work P2.06 as a normal GPIO??

Thanks,

Payal

Hello,

Please have a look at this blog post:  Essential pin planning guidelines for the nRF54L Series . Pins on port 2 do not support interrupts.
