Hi

Buonanno.Antonio

,

You have this configuration code from CubeMx:

RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORTYPE_HSE

|RCC_OSCILLATORTYPE_LSE;

You should removethe

RCC_OSCILLATORTYPE_HSI o

scillator

that you don't need.

This issue is fixed in the CubeMx version 4.1 and you should first EDIT the .ioc file and REMOVEtheRCC.OscillatorType that you don't need

E.g: remove this line

RCC.OscillatorTypeHSI=RCC_OSCILLATORTYPE_HSI

Then re-generate the project, this will resolve your problem.

Hi Imen thanks for your answer,

i create a new file ioc, i see that the system crashes when i active LSE in RTC/LCD source MUX, if i use LSI i don't have problem.

Hello,

I have same problem with ver. 4.21.0.

If I use LSI with RTC I dont have problem.

But when I select LSE, program stuct at void _Error_Handler.

The problem is at this function.

while((hrtc->Instance->ISR & RTC_ISR_INITF) == (uint32_t)RESET)

 {

   if((HAL_GetTick() - tickstart ) > RTC_TIMEOUT_VALUE)

    {

      return HAL_TIMEOUT;

     }

 }

I changed RTC_TIMEOUT_VALUE 1000 to 9000 but still I have problem.

I use stm32f429i discovery board (I had already soldered 32.762khz xtall) and

my .ioc file at link,
