case about ncs v3.0.0 nRF54L15 LFRC calibrate

[peter.min]

Hi,

1.How to determine whether the nRF54L15 LFRC has been calibrated?
2. What logs can show the calibration completion event?
3. Or, apart from logs, what other methods can be used to determine the completion of calibration?

Kind regards,
Peter.Min

Hi,

If you are using the SDK, you normally don't need to handle that as LFRC kalibration is handled by Zephyr. That said, the EVENTS_DONE event for the LFCLK signalles that calibration has completed (you can see examples of it. used here).

There are no logs for this (you would have to add that to the Zephyr implementation to add logging if you need it (or more complicated, but perhaps less intrusive, hook the done evetn to the EGU to generate an interrupt and log from there).
