Hi, I have an issue with CubeIDE and ST-LINK.

I'm trying USART communication with STM32F0F4, I write code and debug but I don't get COM Port. In device manager there is no port showing. I installed st-link009.

I using Tera Term for COM Port connection, ST-Link not showing.

The stand alone ST-LINK/V2 do NOT provide you with a serial port.

You'd need an ST-LINK/V2-1 like those on the DISCO and NUCLEO boards, or the newer ST-LINK/V3

If you look at the schematic for the discovery board, it doesn't have VCP. The only option is to use a USB to Serial adapter and connect to your UART pins.

Or you can use a Nucleo board that which does have VCP. https://www.st.com/en/evaluation-tools/nucleo-f411re.html
