RE: How to set RTC time in nRF9160DK

Hi Hakon,

This example suggests to add RTC0 to spm.c to run in non-secure mode. What does it exactly mean? I'm looking at nrf/subsys/spm/spm.c - enabling RTC0 is behind NRF_RTC0 macro in spm_config_peripherals(). Does it mean that adding "-DNRF_RTC0" to CONFIG_COMPILER_OPT in https://github.com/Rallare/fw-nrfconnect-nrf/blob/nrf9160_samples/samples/nrf9160/nrfx/rtc/prj.conf is enough?

--EDIT--

It seems the following parameters should be added to prj.conf to build the example:

CONFIG_SPM_NRF_RTC0_NS=y
CONFIG_NRFX_RTC=y
CONFIG_NRFX_RTC0=y

With above parameters, the following line is not required:

CONFIG_COMPILER_OPT="-DNRFX_RTC_ENABLED=1 -DNRFX_RTC0_ENABLED=1"

BR,
Adrian

Hello,

there is this "unofficial" RTC sample that you can look at.
