Hardware layout and configuration

Drivers

Before connecting the Nucleo-144 board to a Windows® (XP, 7, 8 and 10) PC via USB,

install the driver for ST-LINK/V2-1 that can be downloaded from the www.st.com website.

If the STM32 Nucleo-144 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-144 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 8.

5.4.2

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 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 the

STM32 Nucleo-144 board. The latest version of this firmware is available from the

www.st.com website.

5.4.3

Using the ST-LINK/V2-1 to program and debug the on-board STM32

To program the on-board STM32, place the two jumpers marked in red on the connector

CN4, as shown in Figure 9. The CN5 connector must not be used, since it could disturb the

communication with the STM32 microcontroller of the Nucleo-144 board.
