I can i2c0 is enabled in zephyr.dts file. Could you please send the application file so I can check and run from my side?

Where can i check that? In the device tree it is enabled. Can you setup a test to check which configuration does work?

Is the TWI disabled in your application?

/{
    arduino_header: connector {
        status = "disabled";
    };
	arduino_adc: analog-connector {
        status = "disabled";
    };
};

&i2c0 {
	status = "okay";
	bme280: bme280@76 {
        status = "okay";
		compatible = "bosch,bme280";
		reg = <0x76>;
        label = "bme280";
	};
};

&pinctrl {
    i2c0_default: i2c0_default {
        group1 {
            psels = <NRF_PSEL(TWIM_SDA, 0, 4)>,
                    <NRF_PSEL(TWIM_SCL, 0, 5)>;
        };
    };
};

Hello,

In default Pin control of nrf53832, P0.27/P0.28 is used for SCk and MISO pin for SPI0. Pin 0.5 is used for RTS of UARTR0. Have you checked if these pins are already used in your application according to board file? Then you need to create overlay file to use these pins for I2C. You can share your overlay file.

Thanks.
