Hi everyone,

I have an STM32F103C8 and I want to programm it form Arduino IDE app.The board is booted and all neded addons are already installed from the board manager. Although when I upload the code the app gives this error:

I've also tried with the USB to TTL device, but it's the same result. Is there any way to fix that problem?

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.
