Hi, Which version are you using? In the latest master I see: #if defined(CONFIG_RTC) /* Initialize the internal RTC hardware. Initialization of external RTC * must be deferred until the system has booted. */
up_rtc_initialize(); #if !defined(CONFIG_RTC_EXTERNAL) /* Initialize the time value to match the RTC */ clock_inittime(NULL); #endif #endif So you propose not to call up_rtc_initialize(); as well?
