nRF52840 custom board zephyr blink sample

Question

Hi. I need some help to change blink led's on zephyr.
I'm using
NRF Connect SDK v1.5.0
SEGGER Embedded Studio for ARM
Release 5.34a Build 2021011401.44914
Nordic Edition
macOS x64 High Sierra v10.13.6

I build my own custom board with a nRF52840 module. These boards is working correctly as I have already tested it with before starting using Zephyr.
I have configured the custom board files on /opt/nordic/ncs/v1.5.0/zephyr/boards/arm, blink example is compiling correctly and I can debug and download.
I can change sleep time which also works correctly.

In .dts file I have configured pins as follow

...
leds {
		compatible = "gpio-leds";
		led0: led_0 {
			gpios = <&gpio0 7 GPIO_ACTIVE_LOW>;
			label = "Green LED 0";
		};
		led1: led_1 {
			gpios = <&gpio0 12 GPIO_ACTIVE_LOW>;
			label = "Green LED 1";
		};

	};
	
...
/* These aliases are provided for compatibility with samples */
	aliases {
		led0 = &led0;
		led1 = &led1;
		pwm-led0 = &pwm_led0;
		sw0 = &button0;
		sw1 = &button1;
		sw2 = &button2;
	};

I have changed blink as follow

#define LED1	""
#define PIN	0
#define FLAGS_1	0
#endif

void main(void)
{
	const struct device *dev_led_0, *dev_led_1;
	//bool led_is_on = true;
	int ret;

        dev_led_0 = device_get_binding(LED0);
        dev_led_1 = device_get_binding(LED1);

	if (dev_led_1 == NULL && dev_led_1 == NULL) { return; }
	
        ret = gpio_pin_configure(dev_led_0, PIN_0, GPIO_OUTPUT_ACTIVE | FLAGS_0);
	if (ret < 0) { return; }

	ret = gpio_pin_configure(dev_led_1, PIN_1, GPIO_OUTPUT_ACTIVE | FLAGS_1);
	if (ret < 0) { return; }


	while (1) {
		//gpio_pin_set(dev_1, PIN_1, (int)led_is_on);
                //gpio_pin_set(dev_0, PIN_0, !((int)led_is_on));
                gpio_pin_toggle(dev_led_0, PIN_1);
                gpio_pin_toggle(dev_led_1, PIN_0);
		//led_is_on = !led_is_on;
		k_msleep(SLEEP_TIME_MS);
	}
}

But just the first led is blinking.
How can I make both led to blink?

Thanks

Find the problem.
After copy board/nrf52840dk_nrf52840 I changed file nrf52840dk_nrf52840.dts
I removed all unneeded codes, Arduino, spi, i2c, uart for my blink test.
One of these were overwriting the led's pins settings.
