STM32G431 LED Toggle Issue – LED Stays ON Until Power Cycle

[Sethnittu]

I am using an STM32G431CBT6. I wrote code to toggle an LED in stm32cubeide. When I build the project in STM32G431, the LED stays permanently ON. However, when I power the board OFF and ON again, the LED starts toggling. Why is this happening?

Hi @Sethnittu 

If your goal is to have a blinking LED, well you have one.

If your goal is to learn how to program an STM32 device, well you need to put some effort into investigating the problem. e.g. Did you consider single stepping (debug mode) into HAL_Delay to see why it never returns?

Roll your sleeves up, put your thinking hat on, and get stuck in to your own debugging!

Ensure USER_VECT_TAB_ADDRESS is uncommented in the system_stm32*.c file.

With recent code/build changes this might be most likely what SysTick doesn't appear to be firing.
