Simple GPIO Example - nRF9160 DK-2

Dear, 

I tried the same code on : 

https://devzone.nordicsemi.com/f/nordic-q-a/43774/simple-gpio-example---nrf9160-dk/173275#173275

and my code:

#include <zephyr.h>
#include <device.h>
#include <gpio.h>

/* 1000 msec = 1 sec */
#define SLEEP_TIME 	5000

void main(void)
{
	int cnt = 0;
	struct device *dev;

	dev = device_get_binding("GPIO_0");
	/* Set LED pin as output */
	gpio_pin_configure(dev, 2, GPIO_DIR_OUT); //p0.03 == LED2
	gpio_pin_configure(dev, 3, GPIO_DIR_OUT); //p0.04 == LED3
        gpio_pin_configure(dev, 4, GPIO_DIR_OUT); //p0.03 == LED2
	gpio_pin_configure(dev, 5, GPIO_DIR_OUT); //p0.04 == LED3
	gpio_pin_configure(dev, 17, GPIO_DIR_OUT); //p0.17
        gpio_pin_configure(dev, 18, GPIO_DIR_OUT); //p0.18
        gpio_pin_configure(dev, 19, GPIO_DIR_OUT); //p0.19

	while (1) {
		/* Set pin to HIGH/LOW every 1 second */
		gpio_pin_write(dev, 2, cnt % 2);	//p0.03 == LED2
		gpio_pin_write(dev, 3, cnt % 2);	//p0.04 == LED3
                gpio_pin_write(dev, 4, cnt % 2);	//p0.03 == LED2
		gpio_pin_write(dev, 5, cnt % 2);	//p0.04 == LED3
		gpio_pin_write(dev, 17, cnt % 2);	//p0.17 Toggling pin 17
                gpio_pin_write(dev, 18, cnt % 2);	//18
                gpio_pin_write(dev, 19, cnt % 2);	//19
		cnt++;
		k_sleep(SLEEP_TIME);
	}
}

The Led1,2,3,4 will on/off in 5s, but P0.17 P0.18 P0.19 didnt change !!

Something else do we need to setup?

the define for gpio;

is it correct?

Plz tell me where is wrong on my code

Thanks
