nrf52840 zephyr interrupt not working

Question

hello Nordic

i am working with nrf52840, with zephyr (i am new to zephyr)

i have an issue with not responding pin interrupt on an input pin

this is my trigger pin configuration:

{
	int ret = 0;
	struct augusi7210_data *drv_data = dev->data;
	const struct augusi7210_dev_config *cfg = dev->config;
	const struct device *alert;

// config as input pin with intrrupt:
	 alert = device_get_binding(cfg->alert_name);
	 if (NULL == alert)
	 {
	 	LOG_ERR("Error: didn't find %s device", cfg->alert_name);
	 	return -ENOTSUP;
	 }

	 ret = gpio_pin_configure(alert, cfg->alert_pin, GPIO_INPUT | cfg->alert_flags);
	 if (ret != 0) 
	 {
	 	LOG_ERR("Error %d: failed to configure %s pin %d", ret, cfg->alert_name, cfg->alert_pin);
	 	return -ENOTSUP;
	 }

	// ret = gpio_pin_interrupt_configure(alert, cfg->alert_pin, GPIO_INT_EDGE_BOTH);
	ret = gpio_pin_interrupt_configure(alert, cfg->alert_pin, GPIO_INT_EDGE_TO_ACTIVE);

	if (ret != 0) 
	{
		LOG_ERR("Error %d: failed to configure interrupt on %s pin %d", ret, cfg->alert_name, cfg->alert_pin);
		return -ENOTSUP;
	}

	// set handler:
	gpio_init_callback(&alert_cb_data, alert_handler, BIT(cfg->alert_pin));
// enable trigger:
	gpio_add_callback(alert, &alert_cb_data);
	LOG_INF("Set up alert at %s pin %d", cfg->alert_name, cfg->alert_pin);


	return 0;
}

this struct is declared globally in the module:

static struct gpio_callback alert_cb_data;

this is the pin set in the dts:

augusi7210@30 {
			compatible = "si,augusi7210";
			reg = <0x30>;
			alert_gpios = <&gpio0 22 GPIO_ACTIVE_HIGH>;
			label = "AUGU_SI7210";

this is the handler:

void alert_handler(const struct device *dev, struct gpio_callback *cb, uint32_t pins)
{
	LOG_ERR("Magnetic Field Senesed");
}

this is the api struct:

static const struct sensor_driver_api augusi7210_driver_api = {
	.trigger_set = augusi7210_trigger_set
};

and this is to my understanding the initiation of it:

#define DT_DRV_COMPAT si_augusi7210

#define AUGU_SI7210_INIT(n)						\
	static const struct augusi7210_dev_config augusi7210_config_##n = {	\
		.i2c_bus_name = DT_BUS_LABEL(DT_DRV_INST(n)),		\
		.i2c_addr = DT_INST_REG_ADDR(n),    \
		.alert_name = COND_CODE_1(DT_NODE_HAS_PROP(DT_DRV_INST(n),alert_gpios), (DT_PROP_BY_PHANDLE_IDX(DT_DRV_INST(n), alert_gpios, 0, label)), (NULL)), \
		.alert_pin = COND_CODE_1(DT_NODE_HAS_PROP(DT_DRV_INST(n),alert_gpios), (DT_PHA_BY_IDX(DT_DRV_INST(n), alert_gpios, 0, pin)), (0)), \
		.alert_flags = COND_CODE_1(DT_NODE_HAS_PROP(DT_DRV_INST(n),alert_gpios), (DT_PHA_BY_IDX(DT_DRV_INST(n), alert_gpios, 0, flags)), (0)) \
	};								\
									\
	static struct augusi7210_data augusi7210_data_##n;	\								
															\
	DEVICE_AND_API_INIT(augusi7210_##n, DT_INST_LABEL(n),	\
			    augusi7210_init, &augusi7210_data_##n,	\
			    &augusi7210_config_##n, APPLICATION,	\
			    CONFIG_SENSOR_INIT_PRIORITY,		\
			    &augusi7210_driver_api);

DT_INST_FOREACH_STATUS_OKAY(AUGU_SI7210_INIT)

when connecting the input pin to vdd of the device i do not get an interrupt .. any ideas will be appreciated

best regards

i am trying to do so on a different thread 
 https://devzone.nordicsemi.com/f/nordic-q-a/80307/nrf52840-with-zephyr-running-button-example-can-t-find-my-board/332679?focus=true 
 
 anyway i found out the problem was something else, the pin gave interrupt all the time because of wrong configuration set which caused the application to get stack.. also i added k_work in the callback of the pin interrupt in the driver just incase
