SDK 2.2 + "__device_dts_ord_XX" errors

[Alskandar]

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 >;
	};
};

Hello

Could you please share the adc node in your generated device tree in build/zephyr/zephyr.dts?

You'll need to add a "compatible" property if it isn't already defined.

I also suspect you might have to add

#address-cells = <1>;
#size-cells = <0>;

to your overlay if you define reg as simply <5>.

Best regards,

Einar

The adc node

adc: feather_adc: arduino_adc: adc@e000 {
				compatible = "nordic,nrf-saadc";
				reg = < 0xe000 0x1000 >;
				interrupts = < 0xe 0x1 >;
				status = "okay";
				#io-channel-cells = < 0x1 >;
				#address-cells = < 0x1 >;
				#size-cells = < 0x0 >;
				phandle = < 0x10 >;
				channel@0 {
					reg = < 0x0 >;
					zephyr,gain = "ADC_GAIN_1_6";
					zephyr,reference = "ADC_REF_INTERNAL";
					zephyr,acquisition-time = < 0x4014 >;
					zephyr,input-positive = < 0x1 >;
					zephyr,resolution = < 0xa >;
				};
				channel@5 {
					reg = < 0x5 >;
					zephyr,gain = "ADC_GAIN_1_6";
					zephyr,reference = "ADC_REF_INTERNAL";
					zephyr,acquisition-time = < 0x4014 >;
					zephyr,input-positive = < 0x6 >;
					zephyr,resolution = < 0xa >;
				};
			};

the gpio node

gpio0: gpio@842500 {
				compatible = "nordic,nrf-gpio";
				gpio-controller;
				reg = < 0x842500 0x300 >;
				#gpio-cells = < 0x2 >;
				status = "okay";
				port = < 0x0 >;
				phandle = < 0xa >;
			};

The #address-cells and #size-cells should be under the channel@x sub-nodes as they give info about the reg properties

I take example from this documentation

In my overlay i have only that:

&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 >;
	};
};

GPIO haven't overlay, and no works too. same error.

If i put #address-cells and #size-cells, errors happened.
I also test to put compatible property, failed too.

Can you please share your project so I can try to replicate?
