Hello @Mine ÇETİNKAYA ,

It could be damaged, issues with power supply, or not wired up correctly.

If NRST pin is connected you can use "connect under reset" to try an wrestle control.

Use STM32 Cube Programmer

Thank you for your reply,

It was about power, I forgot to supply power for PCB. Now, It works!

Thanx a lot again,
