Hi Karl

Thanks a lot. By removing RTC_ENABLED define from sdk_config.h and adding nrfx_rtc.c/.h to my project, it is compiling OK now.

Best regards

John

Hello,

[quote user=""]Adding counter.c to the project with sdk_config.h modified such that NRFX_RTC_ENABLED=1, NRFX_RTC2_ENABLED=1, RTC_ENABLED=1, & RTC2_ENABLED=1.[/quote]

Please remove the legacy RTC_ENABLED define from your sdk_config.h, as this will trigger the apply_old_config to overwrite your NRFX_* sdk configurations.

Have you added the nrfx_rtc .c/.h files to your project?
I would in general recommend that you use the nrfx function calls directly in your code, instead of the legacy nrf_drv_* API.
There are few differences here - especially since the nrf_drv_* calls are macro-forwarded to their equivalent nrfx_ API calls behind the scenes - but it is considered a better practice, and will make maintenance easier later on.

Best regards,
Karl
