Getting started


Nucleo ST-LINK/V2-1 driver installation and firmware upgrade

  • Install the ST-LINK/V2-1 driver before connecting the Nucleo board to your PC the first time. Follow this LINK for all details.
  • For optimum performances, ensure that the Nucleo ST-LINK/V2-1 firmware is upgraded to the latest version (V2.J24.M11 minimum). Follow this LINK for all details.


Virtual Com Port configuration

By default the Virtual Com Port is not enabled. To enable it, you need to close SB14 and SB16 solder bridges.
