RE: case about driver BMA280

Hi,

You need to apply the .overlay file, which also seems to lack the "int1-gpio" definition. I just choose one gpio (P0.27 in this case), which you can freely change to one you have available.

If using "nrf9160dk_nrf9160" as the board, you should name this file "nrf9160dk_nrf9160.overlay":

/*

/*
 * Example configuration of a BME280 device on an Arduino I2C bus.
 *
 * Device address 0x77 is assumed. Your device may have a different
 * address; check your device documentation if unsure.
 */
&arduino_i2c {
	status = "okay";
	bma280@77 {
		compatible = "bosch,bma280";
		reg = <0x77>;
		int1-gpios = <&gpio0 27 0>;
		label = "BMA280_I2C";
	};
};

Then the build file will pick up on the sensor and should compile your project without any errors.

Kind regards,

Håkon
