Embedded STLINK-V3E

The chapter below gives some information about the implementation of STLINK-V3E on this STM32U5
Nucleo-144 board. For details information about ST-LINK capabilities, LED management, driver, and firmware
for this STLINK-V3E, refer to the technical note Overview of ST-LINK derivatives (TN1235).
For information about debugging and programming features of STLINK-V3E, refer to the user manual STLINK-
V3SET debugger/programmer for STM8 and STM32 (UM2448).
6.3.1

Description

There are two different ways to program or debug the onboard STM32 MCU.
• Using the embedded STLINK-V3E
• Using an external debug tool connected to the STDC14/MIPI10 connector (CN5)
Refer to Table 5
The STLINK-V3E facility for debugging and flashing is integrated into the STM32 Nucleo-144 board.
Features supported in STLINK-V3E:
• 5 V / 500 mA power supplied by the USB connector (CN1)
• USB 2.0 high-speed compatible interface
• Serial Wire Debug (SWD) with Serial Wire Viewer (SWV)
• Virtual COM port (VCP)
• 1.7 to 3.6 V application voltage
• COM status LED which blinks during communication with the PC
• USB overcurrent protection (U2)
One tricolor LED, (green, orange, and red) provide information about STLINK-V3E communication status (LD4).
For details information about this LED, refer to the technical note Overview of ST-LINK derivatives (TN1235).
Table 6 describes the USB Micro-B connector (CN1) pinout.

Drivers

The driver installation is not mandatory for Windows
port in the system device manager.
For details information regarding the ST-LINK USB driver, refer to the technical note Overview of ST-LINK
derivatives (TN1235).
6.3.3

STLINK-V3E firmware upgrade

STLINK-V3E embeds a firmware upgrade (stsw-link007) mechanism through the USB port. As the firmware might
evolve during the lifetime of the STLINK-V3E product, to add new functionalities, fix bugs, and support new
microcontroller families, it is recommended to visit the
Nucleo-144 board and periodically, to stay up-to-date with the latest firmware version.
For details information about firmware upgrades, refer to the technical note Overview of ST-LINK derivatives
(TN1235).
