Root Cause

RTC clock drifting significantly from accurate time.

generic

Workarounds

  1. 88% success Calibrate RTC with CALR register compensation value
  2. 90% success Implement NTP or GPS time sync for periodic correction

Dead Ends

Common approaches that don't work:

  1. Ignore drift 72% fail

    Increasing time error

  2. Use HSE as RTC source 68% fail

    Higher power consumption
