STM32CUBE + FreeRTOS + RTC HardFault

Hi Everyone,

I have the stm32f4dicscovery and built a simple project with STM32CubeMX 4.3. I have attached the IOC file. The code starts a task thread and blinks an LED. The program hard faults when the RTC Init function is called. Any help on resolving this would be greatly appreciated.

Call Stack:

HardFault_Handler

xTaskIncrementTick

xPortSysTickHandler

SysTick_Handler

RTC_EnterInitMode

HAL_RTC_Init

MX_RTC_Init

Main

Thanks,

George

Thank you very much the fix was adding this to the FreeRTOSConfig.h file to prevent the hardfault on RTC Init().

#define configUSE_TIME_SLICING 0

Thank You Again,

George
