I have following Problem:


At <65 °C ambient temperature and PowerOff-On.
My STM32f373 works fine.

At> 65 ° C ambient temperature and PowerOff-On

I get a HardFault Error at the following function:


void SystemClock_Config(void)


  if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_2) != HAL_OK)
    _Error_Handler(__FILE__, __LINE__);



What is wrong?

Can someone help me ?


Kind regards
