6.3.1 Drivers

Before connecting the STM32U5 Nucleo-144 board to a Windows 7

, Windows 8

, or Windows 10

PC via USB,

a driver for the STLINK-V3E (stsw-link009) must be installed (not required for Windows 10

). It is available on the

In case the STM32U5 Nucleo-144 board is connected to the PC before the driver is installed, a peripheral may be

declared as “Unknown” in the PC device manager. In this case, the user must install or update the driver files from

the device manager as shown in Figure 7.
