Note:
Drivers
The ST-LINK/V2-1 requires a dedicated USB driver, which can be found on www.st.com for
Windows^® XP, 7, 8.
In case the STM32 Nucleo-144 board is connected to the PC before the driver is installed,
some Nucleo interfaces may be declared as “Unknown” in the PC device manager. In this
case the user must install the driver files (Figure 6), and from the device manager he must
update the driver of the connected device.
Prefer using the “USB Composite Device” handle for a full recovery.

ST-LINK/V2-1 firmware upgrade
The ST-LINK/V2-1 embeds a firmware upgrade mechanism for in-situ upgrade through the
USB port. As the firmware may evolve during the life time of the ST-LINK/V2-1 product (for
example new functionalities, bug fixes, support for new microcontroller families), it is
recommended to visit www.st.com before starting to use the STM32 Nucleo-144 board and
periodically, in order to stay up-to-date with the latest firmware version.
Using the ST-LINK/V2-1 to program and debug
the STM32 on board
To program the STM32 on board, place on the connector CN4 the two jumpers marked in
red, as shown in Figure 7. The CN6 connector must not be used, since it could disturb the
communication with the STM32 microcontroller of the Nucleo-144 board.
