NRF54L15-DK deep sleep, wake up via RTC

[Nikollao]

I am trying to wake up the NRF54L15-DK from deep sleep using RTC. The device goes into deep sleep but never wakes up. I would like to know if RTC can wake up the micro from deep sleep. Is it something I am doing wrong or is this not possible at all?

Hi,

 

Thanks for sharing the log.

The symbol:

warning: attempt to assign the value 'y' to the undefined symbol GRTC_WAKEUP_ENABLE

is local to the sample that I shared here:

Here's the local definition of it: 

https://github.com/nrfconnect/sdk-zephyr/blob/main/samples/boards/nordic/system_off/Kconfig#L16

 

If you are trying to integrate it into your own project, just copy the code directly without the guard for "GRTC_WAKEUP_ENABLE" symbol.

 

Kind regards,

Håkon
