LED won't toggle

I am trying to toggle one of the LED lights of STM32 NUCLEO-L552ZE-Q board. I am working with the latest version of STM32CubeIDE 1.16.1. The steps I followed are given in the picture. However, I find this error when I debugg:

set *(int *)0xE000EDFC=*(int *)0xE000EDFC|0xFF0

Program received signal SIGINT, Interrupt.

0x080006bc in HAL_IncTick () at ../Drivers/STM32L5xx_HAL_Driver/Src/stm32l5xx_hal.c:303

303 }

 

Also, the pics show more. I tried many things to fix this issue but couldn't.

Has someone face the same issue and how did you solve it? Any help is highly appreciated.

I assume it compiles without errors? Can you program with STM32CubeProgrammer?

yes, no errors in compiling. Sure, I can give a try.

Yes, now it works. Thank you very much. :)

Was the debugger halted within the the SystemClock_Config() function at the time this happened?

The variables RCC_OscInitStruct and RCC_ClkInitStruct are local to the SystemClock_Config() function:

 

void SystemClock_Config(void)
{
  RCC_OscInitTypeDef RCC_OscInitStruct = {0};
  RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};

 

Therefore, unless the debugger is actually within that function, those variables do not exist - hence you would get such errors.
