Hello again, hope you've had a good week-end.

Am I understanding it correctly in that you've solved this? If so, great! And I am glad that you've included your solution as well, in case anyone else runs into the same issue in the future.

Regards,

finally, there is no rtc dirver in nordic driver, because rtc is used by softdevice, so we can simulate rtc, then "rtc get rtc_emul" can work well, overaly file like:

/{
	rtc_emul{
		status ="okay";
		compatible = "zephyr,rtc-emul";
		label = "rtc_emul";
		alarms-count = <2>;
	};
};

Please ignore my project B. How should project A be modified to enable RTC? This is the key to the problem. RTC is a commonly used peripheral. Do you have any other suggestions?

Hello,

Just to start off, I want to say that this is a sample from Zephyr, and not directly made by us. Therefore there might be some things that do not work that well with our boards right out of the box, it might need some additional configuration.

If you find dts configurations confusing I would recommend having a look at the DevAcademy course on this.

What does project B consist of?
