RTC Not Working Correctly with FreeRTOS

[LeonSu]

Hello everyone!

We are trying to enable the RTC with FreeRTOS on the STM32U575AII6. The settings are as follows:

1.RCC

2.RTC

3.Clock

4.freeRTOS

Code

void Debug_Printf(char *format, ...)
{
	char buf[128];

	va_list args;
	va_start(args, format);
	uint16_t len = vsnprintf((char *)buf, sizeof(buf), (char *)format, args);
	va_end(args);
	HAL_UART_Transmit(&huart1 ,(uint8_t *)buf,len,150);
}

void RTCTask(void *argument)
{
  /* USER CODE BEGIN RTC_TASK */
	RTC_DateTypeDef Date;
	RTC_TimeTypeDef Time;
  /* Infinite loop */
  for(;;)
  {
	HAL_RTC_GetTime(&hrtc, &Time, RTC_FORMAT_BIN);
	HAL_RTC_GetDate(&hrtc, &Date, RTC_FORMAT_BIN);
	Debug_Printf("%02d:%02d:%02d\n",Time.Hours, Time.Minutes, Time.Seconds);
	osDelay(1000);
  }
  /* USER CODE END RTC_TASK */
}

 and the result output

"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:01\n"
"10:10:02\n"
"10:10:02\n"
"10:10:02\n"
"10:10:02\n"
"10:10:02\n"

The seconds displayed above are wrong.

Any suggestions would be greatly appreciated. Thanks in advance!

Is the rate of printing (once per second) correct?

If you clock it with LSI, does it work as expected? If so, LSE isn't working right.
