SDK 2.2 + "__device_dts_ord_XX" errors

Question

Hi community,

I try to acces gpio0 and adc channels on a icarus board (nRF9160 + SDK 2.2).

On building, i have these errors "__device_dts_ord_94", "__device_dts_ord_95" and "__device_dts_ord_4".

DEVICE_DT_GET seems not accepted.

Any idea to solve this ?
Many thanks !

#define GPIO_NODE DT_NODELABEL(gpio0)
#define ADC_0 DT_CHILD(DT_NODELABEL(adc), channel_0)
#define ADC_5 DT_CHILD(DT_NODELABEL(adc), channel_5)

static const struct device *adc0;
static const struct device *adc5;
static const struct device *gpio;

adc0 = DEVICE_DT_GET(ADC_0);
adc5 = DEVICE_DT_GET(ADC_5);	
gpio = DEVICE_DT_GET(GPIO_NODE);

and overlay

&adc {
	#address-cells = <1>;
	#size-cells = <0>;
	
	channel@0 {
		reg = <0>;
		zephyr,gain = "ADC_GAIN_1_6";
		zephyr,reference = "ADC_REF_INTERNAL";
		zephyr,acquisition-time = <ADC_ACQ_TIME(ADC_ACQ_TIME_MICROSECONDS, 20)>;
		zephyr,input-positive = <NRF_SAADC_AIN0>;
		zephyr,resolution = < 10 >;
	};

	channel@5 {
		reg = <5>;
		zephyr,gain = "ADC_GAIN_1_6";
		zephyr,reference = "ADC_REF_INTERNAL";
		zephyr,acquisition-time = <ADC_ACQ_TIME(ADC_ACQ_TIME_MICROSECONDS, 20)>;
		zephyr,input-positive = <NRF_SAADC_AIN5>;
		zephyr,resolution = < 10 >;
	};
};

It seems like it's difficult accessing the adc channel subnodes using the DEVICE_DT_GET macro. I was able to compile when I exchanged DEVICE_DT_GET with ADC_DT_SPEC_GET_BY_IDX , and adc_channel_setup with adc_channel_setup_dt . My main.c now looks like this: #include // Noyau #include #include // ADC #include // GPIO #include // Calcul #include // Affichage #include // Logging LOG_MODULE_REGISTER(main); #define GPIO_NODE DT_NODELABEL(gpio0) static const struct adc_dt_spec adc_chan0 = ADC_DT_SPEC_GET_BY_IDX(DT_PATH(zephyr_user),0); static const struct adc_dt_spec adc_chan5 = ADC_DT_SPEC_GET_BY_IDX(DT_PATH(zephyr_user),1); static const struct device *gpio_dev; bool init_adc_0() { int err; err = adc_channel_setup_dt(&adc_chan0); if (err) { return false; } return true; } bool init_adc_5() { int err; err = adc_channel_setup_dt(&adc_chan5); if (err) { return false; } return true; } bool init_gpio() { gpio_dev = DEVICE_DT_GET(GPIO_NODE); if (!device_is_ready(gpio_dev)) { return false; }; return true; } int main(void) { init_gpio(); init_adc_0(); init_adc_5(); return true; } And I also had to add this to the overlay: / { zephyr,user { io-channels = <&adc 0>, <&adc 5>; }; }; -Einar
