nrf9160 dk and adxl362 building but not running Error; ADXL362: Unable to get GPIO SPI CS device

[smauelGIS]

Hello,

I am using an Adxl362 accelerometer on nrf9160 dk board.

I followed the tutorial a to add the overlay file and even configure the pins i want to use by flashing an appropiate firmware to the nrf52 SoC.

After all the setUp,configuration and wiring i end up the the error;

[00:00:00.000,061] <err> ADXL362: Unable to get GPIO SPI CS device.

I have been trying to make this work for throughout the entire weekend but i have not been successful.

Please find below the content of my files,

nrf9160_pca10090ns.overlay;

&spi3 {
	compatible = "nordic,nrf-spim";
	status = "okay";
	sck-pin = <3>;
	mosi-pin = <4>;
	miso-pin = <5>;	
	cs-gpios = <&gpio0 8 0>, <&gpio0 7 0>;
	adxl362@0 {
		compatible = "adi,adxl362";
		label = "ADXL362";
		spi-max-frequency = <8000000>;
		reg = <0x00>;
		int1-gpios = <&gpio0 9 0>;
	};
};

 prj.conf;

CONFIG_SPI=y
CONFIG_SENSOR=y
CONFIG_ADXL362=y
CONFIG_ADXL362_TRIGGER_GLOBAL_THREAD=y

CONFIG_SPI_NRFX=y

Im using the adxl362 sample code found in zephyr;

https://github.com/zephyrproject-rtos/zephyr/tree/master/samples/sensor/adxl362

Please let me know what i am doing wrong

Thanks and regards

I don't have the adxl362 sensor at hand at the moment, so I don't have the chance to test this. However, I tested it with a Thingy:91 (which has an adxl362 built-in), and it compiled and run without any errors. Do you have a Thingy:91 to test with? I see your overlay file looks exactly like the spi3 node for the Thingy:91 (except for the adxl372 node), so I am not sure at first sight what may cause the error.

What version of NCS are you using? Make sure to checkout v1.2.0 and run west update.

I can see that device_get_binding() tries to get the device structure of the device with the name "GPIO_0" (config->gpio_cs_port=DT_INST_0_ADI_ADXL362_CS_GPIOS_CONTROLLER="GPIO_0"). The GPIO_0 device structure is created here.

• Could you check if  DT_NORDIC_NRF_GPIO_40842500_LABEL  "GPIO_0" is present in  ..\adxl362\build\zephyr\include\generated\devicetree_unfixed.h
• Just for a test, could you try to set CONFIG_SENSOR_INIT_PRIORITY to a lower priority than CONFIG_KERNEL_INIT_PRIORITY_DEFAULT in prj.conf, and see if the adxl362 sample still fails?

Best regards,

Simon
