I am using the original board. Crystal of 32kHz has not been mounted on this. So, I want to use the internal RC Oscillator. In addition, I use a hrs example of nRF5_SDK_11.0.0.
I write “NRF_CLOCK-> LFCLKSRC = 0” and selected RC oscillator, but do not work.
please tell me how to use the internal RC Oscillator.
Thank you. uba
