Hi Team,

I need help currently we are using nrf52833 micro controller, we have problem with external clocks. we want to disable external 32Mhz and 32khz clocks and use only internal clocks alone. can you please give software how to do that using zephyr.

Hi,

What kind of application to you want to run on this device? You won't be able to use any of the radio protocol stacks without the high-frequency crystal oscillator, as the internal oscillator is too inaccurate for the RADIO. But you can use the internal RC oscillator as the 32K clock source (note: this must normally be calibrated against the HF crystal oscillator to achieve sufficient accuracy).

Which SDK version are you are on?
