LED won't toggle

[emb_rf]

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.

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?

It didn't work unfortunately :(

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. This was the result.

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

Does the LED ever blink?

Or just errors during debugging?

 

[emb_rf]

Just errors during debugging. 

None of these blink.

 

[Karl Yamashita]

Not sure if it'll make a difference but you don't have debugging enabled.

 

I've tried on another Nucleo with Debug off and I don't run into errors. I have a counter variable that still counts up and updates in the Expressions. So that is why i say it may not make a difference if you do enable it.

[emb_rf]

thank you, yes, I also have tried that, but no difference. Still I get the same problem. 

[Karl Yamashita]

I have a lot of Nucleo boards but unfortunately i don't have the one your have. Just out of curiosity, place a breakpoint on SystemClock_Config and MX_GPIO_Init and see if you can get past HAL_Init and SystemClock_Config functions without any errors?

[emb_rf]

No, unfortunately, it gives the same error.

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

[emb_rf]

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