HAL_RCC_OscConfig

[willow]

Hello everyone, 

I am configuring an STM32F401RE and its RTC on the STM32CubeIDE software

I've written an program that debug without errors. But ErrorHandler() is called during the RCC Oscillators initialization (during the "SystemClock_Config(void)" process).

I think i'have followed the steps and the right parameters, but would you have a clue of where could it be from ? Let me know if you need additional pictores of the system configuration of the .ioc file maybe

/** Initializes the RCC Oscillators according to the specified parameters

 * in the RCC_OscInitTypeDef structure.

 */

 RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORTYPE_LSE;

 RCC_OscInitStruct.LSEState = RCC_LSE_ON;

 RCC_OscInitStruct.HSIState = RCC_HSI_ON;

 RCC_OscInitStruct.HSICalibrationValue = RCC_HSICALIBRATION_DEFAULT;

 RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;

 RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSI;

 RCC_OscInitStruct.PLL.PLLM = 16;

 RCC_OscInitStruct.PLL.PLLN = 336;

 RCC_OscInitStruct.PLL.PLLP = RCC_PLLP_DIV4;

 RCC_OscInitStruct.PLL.PLLQ = 7;



if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)

 {

 Error_Handler(); //the call of ErrorHandler() happens here

 }

Hello @willow  and welcome to the community,

Could you please share your ioc file?

[willow]

Of course @mƎALLEm and thank you for your answer, here is my .ioc file attached

Another Top Tip -  for debugging:

The return values from functions like HAL_RCC_OscConfig() are there to tell you what went wrong - so make sure you have some way to see what was returned.

eg, instead of just

if( HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK )
{
   Error_Handler(); //the call of ErrorHandler() happens here
}

do:

HAL_StatusTypeDef HAL_result;                        // Have a variable to catch the result

HAL_result = HAL_RCC_OscConfig(&RCC_OscInitStruct);  // Catch the result

if( HAL_result != HAL_OK )
{
   // Now you can put a breakpoint here, 
   // and see what is in HAL_result 

   Error_Handler(); //the call of ErrorHandler() happens here
}

Hello @willow ,

Thank you for sharing the file.

I didn't reproduce the behavior with NUCLEO-F401 board. Could you confirm you're using that board?

Also did you modify something on it? especially LSE part of the board?

@willow is it a brand new board, straight from the factory, or has it had previous users and/or uses ?

[mƎALLEm]

Check especially that part of the board:

[willow]

Yes in deed, im using the NUCLEO F401RE ! No i didnt modify the hardware

[willow]

it has previous user and uses but always for my project purpose 

[willow]

im gonna try do that and ill update you what it shows, thank you very much
