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 >;
			};

Hi

I just tried to build your project on a fresh NCS install in Ubuntu, and I'm still getting the pm_config.h error.

How did you install NCS?

Did you install it through the nRF Connect for Desktop Toolchain Manager, or did you install it manually?

Have you made any changes to any files in the SDK?

-Einar

[Alskandar]

Hi,

With nRF Connect yes, and no change except copy board files for 2.2 version (no impact, i think).

Board files for Actinius Icarus

[Einarh]

Thanks, that did have an impact, I now get the same error as you.

I'll try to see if I can figure out what's causing your device_dts_ord error then.

-Einar

[Alskandar]

Damned, sorry i wasn't thinking

Thanks for helping

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 <zephyr/kernel.h>				// Noyau
#include <zephyr/device.h>
#include <zephyr/drivers/adc.h>			// ADC
#include <zephyr/drivers/gpio.h>		// GPIO
#include <stdio.h>						// Calcul
#include <zephyr/sys/printk.h>			// Affichage
#include <zephyr/logging/log.h>			// 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>;
	};
};

[Alskandar]

Yes, thanks, but then how i can use functions like 

adc_ref_internal or adc_read ?

They need "const struct device *dev" as 1st parameter

I have not seen adc_read_dt or adc_ref_internal_dt...

[Einarh]

The device structure is actually part of adc_dt_spec.

So you should be able to for example use adc_chan0.dev as the dev parameter for adc_read.

-Einar

[Alskandar]

yes, thanks you !

i find an other solution with your help:

instead DT_CHILD(DT_NODELABEL(adc), channel_0)

directly DEVICE_DT_GET(DT_IO_CHANNELS_CTLR_BY_IDX(DT_PATH(zephyr_user),0))

Ours two solutions still keep errors of type '_device_dts_ord_12' but build and works.

Yes I guess that works too, as long as you run adc_channel_setup.

What do you mean by this exactly?

I'm not seeing any errors when I build.

-Einar

[Alskandar]

This is an error of IntelliSense.

If i modify includePath, librairies are found but i have _device_dts_ord erros

If not, it not found librairies but i haven't errors like _device_dts_ord.

In both case, program is built and works.

This a VSCode problem.
