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?

Am I doing something wrong in the configuration or ???

Perhaps start with one of the NUCLEO-L552 examples in the CubeL5 repository trees, and then add code for LED toggling to that?

Why is your clock at 4MHz? Anyways, why don't you use the Board Selector which will make sure everything is optimally setup including the clock.

It didn't work unfortunately :(

It didn't work. This was the result.

Copy and paste the code you've written. Be sure to use the </> when posting the code.

So I created a new workspace, with all the default settings. The I went to file -> Import -> Existing projects into workspace- 

emb_rf_0-1727631116982.png

Then next. Then I built the code, I tried to debug it and I get this:

So that your code is properly formatted and readable. It's difficult to look at the code the way you pasted it.
