nrf54l15-dk rtc

[dede]

Hi,Team,

I'm currently using the nrf54l15-dk. I want to set the rtc of the nrf54l15-dk to obtain the timestamp. How should I configure the rtc? Which examples should I refer to?
My ncs version is v2.8.0.

Thanks.

Hello,

nRF54L15 does not have a traditional RTC (Real-Time Counter) peripheral like previous nRF series. Instead, it features a GRTC (General Real-Time Counter) and a SYSCOUNTER, which are used for timekeeping and timestamping purposes.

You also need to migrate to NCS 3.0.2.

For implementing timestamp, you should use the Zephyr kernel timer. See the following links:

Hi,

I have updated to NCS 3.0.2. I want to use the nrf54l15 to implement the functions of setting and reading the timestamp. Which project should I refer to?

Thanks.

Hello Kazi!

I have the same issue as OP, I want to get and set RTC on the devkit.

The documentation you linked is for Zephyr 4.2.99 which has sys_clock_gettime() and sys_clock_settime() which look promising.

I updated to NCS 3.1.0 which is the latest version and has Zephyr 4.1.99, which does not have these API functions. Is there any other API I can use?

Regards, Tom
