STLINK-V3SET debugger/programmer for STM8 and STM32

Introduction

The STLINK-V3SET is a stand-alone modular debugging and programming probe for the
STM8 and STM32 microcontrollers. This product is composed of the main module and the
complementary adapter board. It supports the SWIM and JTAG/SWD interfaces for the
communication with any STM8 or STM32 microcontroller located on an application board.

The STLINK-V3SET provides a Virtual COM port interface allowing the host PC to
communicate with the target microcontroller through one UART. It also provides bridge
interfaces to several communication protocols allowing, for instance, the programming of
the target through the bootloader.

The STLINK-V3SET can provide a second Virtual COM port interface allowing the host PC
to communicate with the target microcontroller through another UART (called bridge UART).
Bridge UART signals, including optional RTS and CTS, are available on the adapter board
only (MB1440). The second Virtual COM port activation is done through a reversible
firmware update, which also disables the mass storage interface (used for Drag-and-drop
flash programming).

The modular architecture of STLINK-V3SET enables to extend its main features through
additional modules such as the adapter board.

The serial interface VCP is directly available as a Virtual COM port of the PC, connected to
STLINK-V3SET USB connector CN5. This function can be used for STM32 and STM8
microcontrollers. The signals are 3.3-volt compatible and can perform from 720
15

Mbps. This function is available on MB1441.CN1 and MB1440.CN1.CN3. T_VCP_RX (or
RX) signal is the RX for the target (TX for the STLINK-V3SET), T_VCP_TX (or TX) signal is
the TX for the target (RX for the STLINK-V3SET).

bps to

A second Virtual COM port may be activated, as detailed later in Section 8.3.5 (Bridge
UART).

8.3.5 Bridge functions

The STLINK-V3SET provides a proprietary USB interface allowing communication with any
STM8 or STM32 target with several protocols: SPI, I
interface may be used to communicate with the target bootloader, but may also be used for
customized needs through its public software interface.

All bridge signals can be accessed on CN9 in a simple and easy way by means of wire clips,
with the risk that signal quality and performance are lowered, especially for SPI and UART.
This depends for instance on the quality of the wires used, on the fact that the wires are
shielded or not, and on the layout of the application board.

Bridge SPI

SPI signals are available on MB1440.CN9 and MB1440.CN8. In order to reach high SPI
frequency, it is recommended to use a flat ribbon on MB1440.CN8 with all unused signals
tied to the ground on the target side.

Bridge I2C

I2C signals are available on MB1440.CN9 and MB1440.CN7. The adapter module also
provides optional 680-ohm pull-ups, which can be activated by closing JP10 jumpers. In that
case, the target voltage (T_VCC) must be provided to any of the MB1440 connector
accepting it (CN1, CN2, CN6, or JP10 jumpers).

Bridge CAN

CAN logic signals (Rx/Tx) are available on MB1440.CN9, they can be used as input for an
external CAN transceiver. It is also possible to connect directly the CAN target signals to
MB1440.CN5 (target Tx to CN5.Tx, target Rx to CN5.Rx), provided that:

1. JP7 is closed (CAN ON),

2. CAN voltage is provided to CN5.CAN_VCC.

Bridge UART

UART signals with hardware flow control (CTS/RTS) are available on MB1440.CN9 and
MB1440.CN7. They need a dedicated firmware to be programmed on the main module
before being used. With this firmware, a second Virtual COM port is available and the mass
storage interface (used for Drag-and-drop flash programming) disappears. The firmware
selection is reversible and is done by STLinkUpgrade applications as shown in
The hardware flow control may be activated by physically connecting UART_RTS and/or
UART_CTS signals to the target. If not connected, the second virtual COM port works
without hardware flow control. Note that the hardware flow control activation/deactivation
cannot be configured by software from the host side on a virtual COM port; consequently
configuring a parameter related to that on the host application has no effect on the system
behavior.

In order to reach high UART frequency, it is recommended to use a flat ribbon on
MB1440.CN7 with all unused signals tied to the ground on the target side.

Bridge GPIOs

Four GPIO signals are available on MB1440.CN9 and MB1440.CN8. Basic management is
provided by the public ST bridge software interface.

12.1 Supporting toolchains (not exhaustive)

Tabl e 17 gives a list of the first toolchain version supporting the STLINK-V3SET product.

Table 17. Toolchain versions supporting STLINK-V3SET

Toolchain Description

STM32CubeProgrammer ST Programming tool for ST microcontrollers 1.1.0

SW4STM32 Free IDE on Windows, Linux and macOS 2.4.0

IAR EWARM Third-party debugger for STM32 8.20

Keil MDK-ARM Third-party debugger for STM32 5.26

STVP ST Programming tool for ST microcontrollers 3.4.1

STVD ST Debugging tool for STM8 4.3.12

Note: Some of the very first toolchain versions supporting the STLINK-V3SET (in runtime) may

not install the complete USB driver for STLINK-V3SET (especially the STLINK-V3SET
bridge USB interface description may miss). In that case, either the user switches to a more
recent version of the toolchain, or updates the ST-LINK driver from www.st.com (see

Section 12.2).

Minimum

Ver sion

12.2 Drivers and firmware upgrade

The STLINK-V3SET requires drivers to be installed on Windows and embeds a firmware
which needs to be updated from time to time in order to benefit from new functionality or
corrections. Refer to the Overview of ST-LINK derivatives technical note (TN1235) for
details.

12.3 STLINK-V3SET frequency selection

The STLINK-V3SET can run internally at 3 different frequencies:

• high-performance frequency

• standard frequency, compromising between performance and consumption

• low-consumption frequency

By default, the STLINK-V3SET starts in high-performance frequency. It is the responsibility
of the toolchain provider to propose or not the frequency selection at the user's level.

12.4 Mass storage interface

The STLINK-V3SET implements a virtual mass storage interface allowing the programming
of an STM32 target flash memory with drag-and-drop action of a binary file from a file
explorer. This ability requires the STLINK-V3SET to identify the connected target before

UM2448 Rev 3 29/34

33

Software configuration UM2448

enumerating on the USB host. As a consequence, this functionality is available only if the
target is connected to the STLINK-V3SET before the STLINK-V3SET is plugged to the host.
This functionality is not available for STM8 targets.

The ST-Link firmware programs the dropped binary file, at the beginning of the flash, only if
it is detected as a valid STM32 application according to the following criteria:

• the reset vector points to an address in the target flash area,

• the stack pointer vector points to an address in any of the target RAM area.

If all these conditions are not respected, the binary file is not programmed and the target
flash keeps its initial contents.

12.5 Bridge interface

The STLINK-V3SET implements a USB interface dedicated to bridging functions from USB
to SPI/I
by STM32CubeProgrammer in order to allow target programming through SPI/I
