nRF52: is RTC crystal necessary to execute Zephyr RTOS ?

[vikrant8051]

Can we execute Zephyr RTOS on nRF52832 without RTC crystal & relevant additional components

to reduce PCB size & BoM ?

Hi,

 

As long as zephyr supports using the 32k RC oscillator and properly calibrating it, which it shall have support for, then it shall be fine.

 

Kind regards,
