Originally a reply here, but seems to be a new question.


Thank you, i worked in "Clock Configuration", but RTC is locked . It means for this MCU works only with internal clock for RTC?

So are you talking about the system clock, or the clock for the RTC ?

RTC should be able to run from an internal or external source:

Here the screenshoot

So this is a new question about the RTC clock configuration.

Have you enabled the RTC itself?

What do you mean by "RTC is locked"?

What are the expected behaviour and how does the observation differ from it?

How is the screenshot you've posted relevant to this question?

The RTC part of the screenshot all looks greyed-out - I guess that's what he means by "locked" ?
