Serial Console

The default console is the virtual serial console through ST-LINK:

  1. Nucleo Virtual Console

    The virtual console uses serial port 2 (UART2) with TX on PA2 and RX on PA3.

    VCOM Signal

    Pin

    SERIAL_RX

    PA3

    SERIAL_TX

    PA2

    These signals are internally connected to the on board ST-Link.

    The Nucleo virtual console is the default serial console on all configurations unless stated otherwise in configuration description.

Configurations

nsh:

This configuration provides a basic NuttShell configuration (NSH) on the Nucleo virtual console (VCOM on UART2).

usb-clocks:

This configuration enables the STM32G0 USB device controller and its HSI48 clock source. It provides NSH on the Nucleo virtual console but does not register a USB device class.

usb-cdc:

This configuration extends usb-clocks with the CDC/ACM serial device class and the sercon and serdis commands. Connect an external USB device connector to PA11 (USB DM) and PA12 (USB DP). The CDC/ACM device is registered during board bring-up and enumerates when connected to the host. Run serdis to disconnect it and sercon to connect it again.
