Hello @Пре�?лав Колев and welcome to the Community 🙂

You have to check your connections, and make sure the cable and board are properly connected.

Check that you've selected the right board in Tools > Board and you've selected the right port in Tools > Port.

Try a different USB cable, different board to make sure that you are using the working one.
