HAL_RCC_OscConfig timeout

[EGonc.3]

On initialisation SystemClock_Config(0 calls the function HAL_RCC_OscConfig() and this generates a timeout on the loop below:

   /* Set the new HSE configuration ---------------------------------------*/

   __HAL_RCC_HSE_CONFIG(RCC_OscInitStruct->HSEState);

   /* Check the HSE State */

   if(RCC_OscInitStruct->HSEState != RCC_HSE_OFF)

   {

    /* Get Start Tick*/

    tickstart = HAL_GetTick();

    /* Wait till HSE is ready */

    while(__HAL_RCC_GET_FLAG(RCC_FLAG_HSERDY) == 0U)

    {

     if((uint32_t) (HAL_GetTick() - tickstart ) > HSE_TIMEOUT_VALUE)

     {

      return HAL_TIMEOUT; <<------

     }

    }

Any ideas what could be the cause of this and how to solve it?

thanks

Are you using a simulator or an RTOS?

What are your settings for the HSE timeout value (see block RCC, if created using CubeMX/CubeIDE)?

regarding your questions:

>Are you using a simulator or an RTOS?

I'm using FreeRTOS

The HAL_Ticker seems to be working fine.

I have used CubeMX to generate the configuration.

I'm using a STM32H7A3 processor on a Nucleo board, and somehow the RCC was wrong.

Now it's High Speed Clocmk = Crystal/Ceramic Resonator

Low Speed Clock: Disable

(For some reason it was enabling the Low Speed Clock!)

Still I have a problem now:

When is calling HAL_GetTick() on the second call below it generates an error: <signal handler called>() at 0xfffffff9

   /* Get Start Tick*/

   tickstart = HAL_GetTick();

    while (__HAL_RCC_GET_SYSCLK_SOURCE() != (RCC_ClkInitStruct->SYSCLKSource << RCC_CFGR_SWS_Pos))

    {

     if((HAL_GetTick() - tickstart ) > CLOCKSWITCH_TIMEOUT_VALUE) <----

     {

      return HAL_TIMEOUT;

     }

    }

I have the same issue, a custom board that was already working i created a simple project and never gets pass SystemClock_Config();

Doesnt matter if i use HSE or HSI

my timeout values are the default ones
