Embedded STLINK-V3EC

The chapter below gives some information about the implementation of STLINK-V3EC.
For more details on STLINK-V3EC such as LEDs management, drivers, and firmware, refer to the technical note
Overview of ST-LINK derivatives (TN1235).
For information about the debugging and programming features of STLINK-V3EC, refer to the user manual
STLINK-V3SET debugger/programmer for STM8 and STM32 (UM2448).

Description

There are two different ways to program and debug the onboard STM32 MCU.
• Using the embedded STLINK-V3EC
• Using an external debug tool connected to the CN4 STDC14/MIPI10 connector
Refer to Table 5
The STLINK-V3EC facility for debugging and flashing is integrated into the STM32H5 Nucleo-64 board.
Supported features in STLINK-V3EC:
• 5 V/500 mA power supply capability through the USB Type-C
• USB 2.0 high-speed-compatible interface
• JTAG and Serial Wire Debug (SWD) with Serial Wire Viewer (SWV)
• Virtual COM port (VCP)
• 3.3 V application voltage
• COM status LED, which blinks during communication with the PC
• Power status LED giving information about STLINK-V3EC target power
• USB-C overvoltage protection (U5) with current limitation
Two tricolor LEDs (green, orange, and red) provide information about STLINK-V3EC communication status (LD1)
and STLINK-V3EC power status (LD7).
For detailed information about the management of these LEDs, refer to the technical note Overview of ST-LINK
derivatives (TN1235).
7.1.1

Drivers

The installation of drivers is not mandatory from Windows 10
COM port in the system device manager.
For detailed information on the ST-LINK USB drivers, refer to the technical note Overview of ST-LINK derivatives
(TN1235).
7.1.2

STLINK-V3EC firmware upgrade

STLINK-V3EC embeds a firmware upgrade (stsw-link007) mechanism through the USB-C port. As the firmware
might evolve during the lifetime of the STLINK-V3EC product (for example to add new functionalities, fix bugs,
and support new microcontroller families), it is recommended to keep the STLINK-V3EC firmware up to date
before starting to use the NUCLEO-H503RB board. The latest version of this firmware is available from the
www.st.com website.
For detailed information about firmware upgrades, refer to the technical note Overview of ST-LINK derivatives
(TN1235).
