How to compile sample 'BME68X: Gas Sensor' on nRF5340 DK

[Yanpengwu]

Hi Support Team,

I want to run the sample 'BME68X: Gas Sensor' on nRF5340-DK. Following the desrciption of BME68X IAQ driver, I download the BSEC lib to my SDK(ncs v2.5.2).

In the 'Build Configuration', I set Board=nrf5340dk_nrf5340_cpuapp and added an overlay as below:

 &i2c1 {
	compatible = "nordic,nrf-twim";
	bme680: bme680@77 {
		compatible = "bosch,bme680";
		reg = <0x77>;
	};
};

With the sample code, there is a compiling error for 'undefined reference to `__device_dts_ord_134'', the error info as below:

[1/6] Linking C executable zephyr\zephyr_pre0.elf
...
c:/ncs/toolchains/cf2149caf2/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/12.2.0/../../../../arm-zephyr-eabi/bin/ld.bfd.exe: app/libapp.a(main.c.obj): in function `main':
C:/ncs/v2.5.2/nrf/samples/sensor/bme68x_iaq/src/main.c:61: undefined reference to `__device_dts_ord_134'

Could you help check how to compile this sample for nRF5340-DK? Thank you very much.

Best regards,
Yanpeng Wu

Hello Wu,

''undefined reference to `__device_dts_ord_134'' This error is related to peripheral. 

Can you change i2c1 to i2c0 (if it is free) in the overlay file?

Thanks.

Hi Kazi,

The problem was fixed. All of the above configurations and overlays are correct.
The root cause is the BSEC lib needs a partition for internal state storage, when I enabled the partition manager and made sure there is a 'settings_storage' partition in the file build\partitions.yml, the compilation was successful.

Best regards,

Hello Yanpeng,

Great that you have solved the problem. It seems that the problem was related to the BSEC library; it could be mixed with NCS.
