Have you tried to reset your microcontroller after uploading code? If you are using a nucleo board simply press reset button (also make sure it runs on newest firmware).

Yes i reset microcontroller, changed cables, reset my PC but it didnt change.

Hello there!

You could try to clean the project (right click -> clean project) in the Project Explorer view. Also, with STM32CubeProgrammer standalone you could connect to the board and clean it to be 100% certain that the flash is cleaned before the new debug session.

STM32CubeProgrammer standalone is available for free here.

I did the things that you say but anything changed.

Can this problem happen because of my st link ?

[Markus GIRDLAND]

What board are you using? Maybe if I have one in the office I can create a project which works for me and send it to you.

STM32F103C8 ( Blue Pill) and St-link Mini Sir. I tried program with Cube IDE.

Pleas show your pin configuration window, how GPIOs are configured. Also check if LED_GPIO_Port and LED_Pin are connected to the LED on the board you use.

I tried another bluepill, it worked.
