,
Thanks for your feedback,
In fact, the idea is to let the user insert his own code using habitual USER TAGs when he doesn't want to re-initialize RTC peripheral.
As you can see, in CubeMX 4.26 version, we have added USER TAGs in the MX_RTC_Init(void) where user can add his own code.
static void MX_RTC_Init(void)
{
/* USER CODE BEGIN RTC_Init 0 */
/* USER CODE END RTC_Init 0 */
RTC_TimeTypeDef sTime;
RTC_DateTypeDef sDate;
/* USER CODE BEGIN RTC_Init 1 */
/* USER CODE END RTC_Init 1 */
/**Initialize RTC Only
*/
hrtc.Instance = RTC;
hrtc.Init.HourFormat = RTC_HOURFORMAT_24;
hrtc.Init.AsynchPrediv = 127;
hrtc.Init.SynchPrediv = 255;
hrtc.Init.OutPut = RTC_OUTPUT_DISABLE;
hrtc.Init.OutPutPolarity = RTC_OUTPUT_POLARITY_HIGH;
hrtc.Init.OutPutType = RTC_OUTPUT_TYPE_OPENDRAIN;
if (HAL_RTC_Init(&hrtc) != HAL_OK)
{
_Error_Handler(__FILE__, __LINE__);
}
/* USER CODE BEGIN RTC_Init 2 */
/* USER CODE END RTC_Init 2 */
/**Initialize RTC and set the Time and Date
*/
sTime.Hours = 0x0;
sTime.Minutes = 0x0;
sTime.Seconds = 0x0;
sTime.DayLightSaving = RTC_DAYLIGHTSAVING_NONE;
sTime.StoreOperation = RTC_STOREOPERATION_RESET;
if (HAL_RTC_SetTime(&hrtc, &sTime, RTC_FORMAT_BCD) != HAL_OK)
{
_Error_Handler(__FILE__, __LINE__);
}
/* USER CODE BEGIN RTC_Init 3 */
/* USER CODE END RTC_Init 3 */
sDate.WeekDay = RTC_WEEKDAY_MONDAY;
sDate.Month = RTC_MONTH_JANUARY;
sDate.Date = 0x1;
sDate.Year = 0x0;
if (HAL_RTC_SetDate(&hrtc, &sDate, RTC_FORMAT_BCD) != HAL_OK)
{
_Error_Handler(__FILE__, __LINE__);
}
/* USER CODE BEGIN RTC_Init 4 */
/* USER CODE END RTC_Init 4 */
}
Also, in addition to the backup register, there are others solutions to remain the RTC initialization. It depends on user application. For example, you may also use RTC & PWR flags to determine whether RTC is already initialized or a HW/SW reset has been occurred. So, we can not force user to use backup register solution to remain
RTC initialization.
Hoping it helps you, please do not hesitate to contact me for further details.
Best Regards,
Mohamed.
