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 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 only available on the MB1440 adapter board. 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 the extension of its main features through additional modules such as the adapter board for different connectors, the BSTLINK-VOLT board for voltage adaptation, and the B-STLINK- ISOL board for voltage adaptation and galvanic isolation.

STLINK-V3SET functional description

7.1 STLINK-V3SET overview
The STLINK-V3SET is a stand-alone modular debugging and programming probe for the STM8 and STM32 microcontrollers. This product supports many functions and protocols for debugging, programming, or communicating with one or several targets. The STLINKV3SET package includes
complete hardware with the main module for high performance and an adapter board for added functions to connect with wires or flat cables anywhere into the application.
This module is fully powered by the PC. If the COM LED blinks red, refer to the technical note Overview of ST-LINK derivatives (TN1235) for details.
7.1.1 Main module for high performance
This configuration is the preferred one for high performance. It only supports STM32 microcontrollers. The working voltage range is from 3 V to 3.6 V.
Figure 2. Probe top side

The protocols and functions supported are:

• SWD (up to 24 MHz) with SWO (up to 16 MHz)
• JTAG (up to 21 MHz)
• VCP (from 732 bps to 16 Mbps)

A 2×7-pin 1.27 mm pitch male connector is located in the STLINK-V3SET for connection to the application target. Three different flat cables are included in the packaging to connect with standard connectors MIPI10/ARM10, STDC14, and ARM20 (refer to Section 9: Flat ribbons on page 29).
See Figure 3 for connections:
7.1.2 Adapter configuration for added functions
This configuration favors the connection to targets using wires or flat cables. It is composed of MB1441 and MB1440. It supports debugging, programming, and communicating with STM32 and STM8 microcontrollers.

7.1.3 How to build the adapter configuration for added functions
See the operating mode below to build the adapter configuration from the main module configuration and back..

7.2 Hardware layout
The STLINK-V3SET product is designed around the STM32F723 microcontroller (176-pin in UFBGA package). The hardware board pictures (Figure 6 and Figure 7) show the two boards included in the package in their standard configurations (components and jumpers). Figure 8, Figure 9, and Figure 10 help users locate the features on the boards. The mechanical dimensions of the STLINK-V3SET product are shown in Figure 11 and Figure 12.

7.3 STLINK-V3SET functions
All functions have been designed for high performance: all signals are 3.3-volt compatible except the SWIM protocol, which supports a voltage range from 1.65 V to 5.5 V. The following description concerns the two boards MB1441 and MB1440 and indicates where to find the functions on the boards and connectors. The main module for high performance only includes the MB1441 board. The adapter configuration for added functions includes both the MB1441 and MB1440 boards.
7.3.1 SWD with SWV
SWD protocol is a Debug/Program protocol used for STM32 microcontrollers with SWV as a trace. The signals are 3.3 V compatible and can perform up to 24 MHz. This function is available on MB1440 CN1, CN2, and CN6, and MB1441 CN1. For details regarding baud rates, refer to Section 14.2.
7.3.2 JTAG
JTAG protocol is a Debug/Program protocol used for STM32 microcontrollers. The signals are 3.3-volt compatible and can perform up to 21 MHz. This function is available on MB1440 CN1 and CN2, and MB1441 CN1.
The STLINK-V3SET does not support the chaining of devices in JTAG (daisy chain).
For correct operation, the STLINK-V3SET microcontroller on the MB1441 board requires a JTAG return clock. By default, this return clock is provided through the closed jumper JP1 on MB1441, but may also be externally provided through pin 9 of CN1 (This configuration may be necessary to reach high JTAG frequencies; in this case, JP1 on MB1441 must be opened). In case of use with the B-STLINK-VOLT extension board, the JTAG clock loopback must be removed from the STLINK-V3SET board (JP1 opened). For the correct functioning of JTAG, the loopback must be done either on the B-STLINK-VOLT extension board (JP1 closed) or on the target application side.
7.3.3 SWIM
SWIM protocol is a Debug/Program protocol used for STM8 microcontrollers. JP3, JP4, and JP6 on the MB1440 board must be ON to activate the SWIM protocol. JP2 on the MB1441 board must also be ON (default position). The signals are available on the MB1440 CN4 connector and a voltage range from 1.65 V to 5.5 V is supported. Note that a 680 Ω pull-up to VCC, pin 1 of MB1440 CN4, is provided on DIO, pin 2 of MB1440 CN4, and consequently:
• No additional external pull-up is required.
• VCC of MB1440 CN4 must be connected to Vtarget.
7.3.4 Virtual COM port (VCP)
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 V compatible and can perform from 732 bps to 16 Mbps. This function is available on MB1440 CN1 and CN3, and MB1441 CN1. 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). A second Virtual COM port may be activated, as detailed later in Section 7.3.5 (Bridge UART).
For details regarding baud rates, refer to Section 14.2.
7.3.5 Bridge functions
The STLINK-V3SET provides a proprietary USB interface allowing communication with any STM8 or STM32 target with several protocols: SPI, I 2
C, CAN, UART, and GPIOs. This 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 simply and easily accessed on CN9 using 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 CN8 and CN9. To reach a 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 I ²C 2 I
C signals are available on MB1440 CN7 and CN9. The adapter module also provides optional 680-ohm pull-ups, which can be activated by closing JP10 jumpers. In that case, the T_VCC target voltage must be provided to any of the MB1440 connectors 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, meaning CAN is 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 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 Figure 13. 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. To reach a 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.

For details regarding baud rates, refer to Section 14.2.
Bridge GPIOs
Four GPIO signals are available on MB1440 CN8 and CN9. Basic management is provided by the public ST bridge software interface.
7.3.6 LEDs
PWR LED: red light indicates that 5 V is enabled (only used when a daughterboard is plugged).
COM LED: refer to the technical note Overview of ST-LINK derivatives (TN1235) for details.

• standard frequency, compromising between performance and consumption
• low-consumption frequency

By default, the STLINK-V3SET starts at a high-performance frequency. It is the responsibility of the toolchain provider to propose or not the frequency selection at the user level.
11.4 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 enumerating it 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 into 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 areas.

If all these conditions are not respected, the binary file is not programmed and the target flash keeps its initial contents.
11.5 Bridge interface
The STLINK-V3SET implements a USB interface dedicated to bridging functions from USB to SPI/I 2
C/CAN/UART/GPIOs of the ST microcontroller target. This interface is firstly used by STM32CubeProgrammer to allow target programming through SPI/I 2 C/CAN bootloader.
A host software API is provided to extend the use cases.

12.3 Selection of bridge GPIO direction
The level-shifter components on the B-STLINK-VOLT board require to manually configure the direction of bridge GPIO signals. This is possible through the SW1 switch on the bottom of the board. Pin1 of SW1 is for bridge GPIO0, pin4 of SW1 is for bridge GPIO3. By default, the direction is target output/ST-LINK input (selectors on ON/CTS3 side of SW1). It can be changed for each GPIO independently into the target input/ST-LINK output direction by moving the corresponding selector on the ‘1’, ‘2’, ‘3’, or ‘4’ side of SW1. Refer to Figure 18.

12.4 Jumper configuration
Caution: Always remove the JP1 jumper from the STLINK-V3SET main module (MB1441) before stacking the B-STLINK-VOLT board (MB1598). This jumper can be used on the MB1598 board to provide the return JTAG clock required for correct JTAG operations. If the JTAG clock loopback is not done at the B-STLINK-VOLT board level through JP1, it must be done externally between CN1 pins 6 and 9.

Performance figures

14.1 Global overview
Table 19 gives an overview of the achievable maximal performances with the STLINKV3SET on different communication channels. Those performances are also depending on the overall system context (target included), so they are not guaranteed to be always reachable. For instance, a noisy environment or the connection quality can impact system performance.
Table 19. Achievable maximal performance with STLINK-V3SET on different channels
14.2 Baud rate computing
Some interfaces (VCP and SWV) are using the UART protocol. In that case, the baud rate of STLINK-V3SET must be aligned as much as possible with the target one.
Below is a rule allowing to compute the baud rates achievable by the STLINK- V3SET probe:

• In high-performance mode: 384 MHz / prescaler with prescaler = [24 to 31] then 192 MHz / prescaler with prescaler = [16 to 65535]
• In standard mode: 192 MHz/prescaler with prescaler = [24 to 31] then 96 MHz / prescaler with prescaler = [16 to 65535]
• In low consumption mode: 96 MHz / prescaler with prescaler = [24 to 31] then 48 MHz / prescaler with prescaler = [16 to 65535] Note that the UART protocol does not guaranty the data delivery (all the more without hardware flow control). Consequently, at high frequencies, the baud rate is not the only parameter impacting the data integrity. The line load rate and the capability for the receiver to process all the data also affect the communication. With a heavily loaded line, some data loss may occur at the STLINK-V3SET side above 12 MHz.
