Hi,
The RTC_XTALI and RTC_XTALO were kept floating in my custom hardware.In the case,some of boards will switch internal low frequency ring oscillator to an external clock source which is inaccurate.Consequently,if I enable watchdog,it will restart within random seconds.
So is there a way to disable switching internal low frequency ring oscillator to an external clock source in software?
Regards,
