hi,
I configure my micro to work on internal clock by cubemx - this is the clock configure:
//#############################################################################################################
// Init Device: System Clock Configuration
//#############################################################################################################
static void IDM_Config_System_Clock(void)
{
RCC_OscInitTypeDef RCC_OscInitStruct = {0};
RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};
/** Initializes the RCC Oscillators according to the specified parameters
* in the RCC_OscInitTypeDef structure.
*/
RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORTYPE_LSI1;
RCC_OscInitStruct.HSIState = RCC_HSI_ON;
RCC_OscInitStruct.HSICalibrationValue = RCC_HSICALIBRATION_DEFAULT;
RCC_OscInitStruct.LSIState = RCC_LSI_ON;
RCC_OscInitStruct.PLL.PLLState = RCC_PLL_NONE;
if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
{
Error_Handler();
}
/** Configure the SYSCLKSource, HCLK, PCLK1 and PCLK2 clocks dividers
*/
RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK4|RCC_CLOCKTYPE_HCLK2
|RCC_CLOCKTYPE_HCLK|RCC_CLOCKTYPE_SYSCLK
|RCC_CLOCKTYPE_PCLK1|RCC_CLOCKTYPE_PCLK2;
RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_HSI;
RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1;
RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV1;
RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV1;
RCC_ClkInitStruct.AHBCLK2Divider = RCC_SYSCLK_DIV1;
RCC_ClkInitStruct.AHBCLK4Divider = RCC_SYSCLK_DIV1;
if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_0) != HAL_OK)
{
Error_Handler();
}
}
and this is the RTC init function:
static void IDM_RTC_Init(void)
{
RTC_Object.Instance = RTC;
RTC_Object.Init.HourFormat = RTC_HOURFORMAT_24;
RTC_Object.Init.AsynchPrediv = 127;
RTC_Object.Init.SynchPrediv = 255;
RTC_Object.Init.OutPut = RTC_OUTPUT_DISABLE;
RTC_Object.Init.OutPutPolarity = RTC_OUTPUT_POLARITY_HIGH;
RTC_Object.Init.OutPutRemap = RTC_OUTPUT_REMAP_NONE;
if (HAL_RTC_Init(&RTC_Object) != HAL_OK)
{
Error_Handler();
}
}
but rtc init is failed, its occured on RTC_EnterInitMode() function
HAL_StatusTypeDef RTC_EnterInitMode(RTC_HandleTypeDef *hrtc)
{
uint32_t tickstart;
/* Check if the Initialization mode is set */
if ((hrtc->Instance->ISR & RTC_ISR_INITF) == 0U)
{
/* Set the Initialization mode */
hrtc->Instance->ISR = (uint32_t)RTC_INIT_MASK;
tickstart = HAL_GetTick();
/* Wait till RTC is in INIT state and if Time out is reached exit */
while ((hrtc->Instance->ISR & RTC_ISR_INITF) == 0U)
{
if ((HAL_GetTick() - tickstart) > RTC_TIMEOUT_VALUE)
{
I RECEIVED THE TIMEOUT ERROR HERE:
return HAL_TIMEOUT;
}
}
}
return HAL_OK;
}
I tried everything without success :(
Can anyone help me to understand where the problem is?
