Thingy53: how to enable bmi270 on board correctly?

[danny0007]

Hi community,

ncs-2.6.0 I'm using.

I'm trying to enable bmi270 as I enabled adxl362(is already working), both are connected with SPI.

CONFIG_ADXL362=y
CONFIG_BMI270=y

but it shows me this kind of infomation:

CONFIG_BMI270 was assigned the value y, but got the value n. Missing dependencies:
DT_HAS_BOSCH_BMI270_ENABLED

BMI270 Inertial measurement unit

Type: bool

Value: n

Enable driver for BMI270 I2C-based imu sensor

after check the Kconfig file of BMI270 I find this:

it´s  a little complex for me as a newbie, so how to enable the bmi270 on board of thingy53?


Best regards,

Danny

Hi

Can you show me your devicetree and your prj.conf?

};

in overlay file:
&spi3{

		status = "okay";
	};
};

Thanks

Did you do a prestine build after changes your prj.conf and overlay?

I tried with NCS 2.6.1. Which version are you using?

Build target thingy53_nrf5340_cpuapp_ns

prj.conf 

# nothing here
CONFIG_GPIO=y
CONFIG_SPI=y
CONFIG_SENSOR=y
CONFIG_BMI270=y

Overlay

&spi3{
	bmi270: spi-dev-bmi270@1 {
		status = "okay";
	};
};

main

#include <zephyr/kernel.h>

int main(void)
{
	const struct device *sensor = DEVICE_DT_GET_ANY(bmi270);

	if (!device_is_ready(sensor)) 
	{
		printk("Sensor device not ready\n");
		return;
	}
	printk("Hello World! %s\n", CONFIG_BOARD);
	return 0;
}

And I was not able to replicate your warning
