Wake up from System Off with RTC

[MichaelGK]

Hello community

I have tested the v3.2.1\zephyr\samples\boards\nordic\system_off example and it works fine on my nrf54l15dk. Now i wanted to use parts of it for my custom board and i found out that the example uses the kernel function 

int z_nrf_grtc_wakeup_prepare(uint64_t wake_time_us)

to setup the rtc for waking up the device after a certain amount of time. Is this really ok from user space? I have heart that z_ functions should never be called from an application code!

best regards

Michael

Hi Michael

You are right, and it seems like the nrf_grtc_timer driver has used this z_ prefix without heeding this. It should be fine to use since it's not an internal Zephyr function, but I will create an internal ticket to fix this in future NCS versions.

Best regards,

Simon
