6.4.1 Drivers
Before connecting the STM32 Nucleo-64 board to a Windows
®
 PC (7, 8, or 10) through 
USB, install the driver for the ST-LINK/V2-1 that is available at the www.st.com website.
In case the STM32 Nucleo-64 board is connected to the PC before installing the driver, the 
PC device manager may report some Nucleo interfaces as ‘Unknown’. To recover from this 
situation, after installing the dedicated driver, the association of ‘Unknown’ USB devices 
found on the STM32 Nucleo-64 board to this dedicated driver, must be updated in the 
device manager manually.
Note: It is recommended to proceed by using USB Composite Device, as shown in Figure 6.

6.4.2  ST-LINK/V2-1 firmware upgrade
The ST-LINK/V2-1 embeds a firmware upgrade mechanism for the in-situ upgrade through 
the USB port. As the firmware may evolve during the lifetime of the ST-LINK/V2-1 product 
(for example new functionalities, bug fixes, support for new microcontroller families), it is 
recommended to keep the ST-LINK/V2-1 firmware up to date before starting to use an 
STM32 Nucleo-64 board. The latest version of this firmware is available at the www.st.com 
website.
6.4.3  Using the ST-LINK/V2-1 to program/debug the STM32 on board
To program the STM32 on board, simply plug in the two jumpers on CN4, as shown in 
Figure 7 in pink, but do not use the CN11 connector as that may disturb communication with 
the STM32 microcontroller of the Nucleo.
