8.3 Embedded ST_LINK/V2-1
The ST-LINK/V2-1 programming and debugging tool is integrated on the STM32H743I-
EVAL Evaluation board. Compared to ST-LINK/V2 the changes are listed below.
The new features supported on ST-LINK/V2-1 are:
•USB software re-enumeration
•Virtual COM port interface on USB
•Mass storage interface on USB
•USB power management request for more than 100mA power on USB
This feature is no more supported on ST-LINK/V2-1: SWIM interface
For all general information concerning debugging and programming features common
between V2 and V2-1 versions, refer to ST-LINK/V2 in-circuit debugger/programmer for
STM8 and STM32 User manual (UM1075) at the www.st.com website.
Note:1 It is possible to power the Evaluation board through CN23 (Embedded ST-LINK/V2-1 USB
connector) even if an external tool is connected to CN8 (ETM Trace connector) or CN9
(External JTAG and SWD connector).
Note:2 ETM can only work at 50 MHz clock by default because ETM signals are shared with other
peripherals. If better performance of ETM is required (84 MHz/98 MHz), R217, R230, R231,
R234, R236, SB2, SB5, SB8, SB11, SB42, SB57 must be removed to reduce the stub on
ETM signals. In this configuration SAI and PDM are not functional and NOR Flash and the
address of SRAM are limited on A18.
Note:3 ETM trace function would be abnormal as SAI_SDB share the same pins with TRACE_D0,
and TRACE_D0 would be forced high by SAI_SDB. When using ETM trace it is necessary
to set ADCDAT1 pin (SAI_SDB signal of the STM32) of audio codec WM8994ECS/R (U22)
by software to be tri-state.
8.3.1 Drivers
Before connecting the STM32H743I-EVAL Evaluation board to a Windows® PC (XP, 7, 8 or
10) through a USB, a driver for the ST-LINK/V2-1 must be installed. It is available at the
www.st.com website.
In case the STM32H743I-EVAL Evaluation board is connected to the PC before the driver is
installed, some STM32H743I-EVAL interfaces may be declared as "unknown" in the PC
device manager. To recover from this situation the user has to install the driver files, and
update the driver of the connected device from the device manager (see Figure 5).
Note: Prefer using the "USB Composite Device" handle for a full recovery.

8.3.2 ST-LINK/V2-1 firmware upgrade
The ST-LINK/V2-1 embeds a firmware upgrade mechanism for in-situ upgrade through the
USB port. As the firmware may evolve during the life time of the ST-LINK/V2-1 product (for
example new functionalities, bug fixes, support for new microcontroller families), it is
recommended to visit www.st.com before starting to use the STM32H743I-EVAL Evaluation
board and periodically, to stay up-to-date with the latest firmware version.
8.4 Power Supply
The STM32H743I-EVAL Evaluation board is designed to be powered by 5 V DC power
supply and is protected by PolyZen from wrong power plug-in events. It is possible to
configure the Evaluation board to use any of the following six sources for the power supply:
•5 V DC power adapter connected to CN10, the power jack on the board (Power Supply
Unit on silk screen of JP10 (PSU)).
•5 V DC power with 500 mA limitation from CN23, the USB Micro-B connector of ST-
LINK/V2-1 (USB 5 V power source on silkscreen of JP10 (STlk)). If the USB
enumeration succeeds (as explained below), the ST-LINK U5V power is enabled, by
asserting the PWR_EN pin. This pin is connected to a power switch (ST890) that
powers the board. This power switch features also a current limitation to protect the PC
in case of short-circuit on the board. If overcurrent (more than 600 mA) happens on the
board, the LED LD11 lights up.
•5 V DC power with 500 mA limitation from CN14, the USB OTG2 HS Micro-AB
connector (USB 5V power source on silkscreen of JP10 (HS)).
•5 V DC power with 500 mA limitation from CN18, the USB OTG1 FS Micro-AB
connector (USB 5V power source on silkscreen of JP10 (FS1)).
•5 V DC power with 500 mA limitation from CN16, the USB OTG2 FS Micro-AB
connector (USB 5V power source on silkscreen of JP10 (FS2)).
•5 V DC power from CN6 and CN7, the extension connectors for daughterboard
(daughterboard power source on silkscreen of JP10 (D5V)).
The STM32H743I-EVAL Evaluation board can be powered from the ST-LINK/V2-1 USB
connector CN23 (U5V), but only the ST-LINK/V2-1 circuit has the power before USB
enumeration, because the host PC only provides 100 mA to the board at that time. During
the USB enumeration phase the STM32H743I-EVAL board requires 300 mA power from the
Hardware layout and configuration UM2198
14/69 DocID030511 Rev 1
host PC. If the host is able to provide the required power, the enumeration succeeds, the
power transistor U19 (ST890) is switched ON, the red LED LD9 is turned ON, and thus the
STM32H743I-EVAL board is powered and can consume maximum 300 mA current. If the
host PC is not able to provide the requested current, the enumeration fails. Therefore the
STM32 part including the extension board is not powered. As a consequence the red LED
LD9 remains turned OFF. In this case it is mandatory to use an external power supply to
supply extra power.
E5V (from PSU) or D5V can be used as an external power supply in case the current
consumption of the STM32H743I-EVAL board exceeds the allowed current on USB. In this
condition it is still possible to use USB for communication, programming or debugging only,
but it is mandatory to power the board first using E5V or D5V, and then connecting the USB
cable to the PC. Proceeding this way ensures that the enumeration succeeds thanks to the
external power source.
The following power sequence procedure must be respected:
1. Connect jumper JP10 for PSU or D5V side
2. Check that JP15 is removed
3. Connect the external power source to PSU or D5V (daughterboard mounted)
4. Check red LED LD9 is turned ON
5. Connect the PC to USB connector CN23
If this order is not respected, the board may be powered by VBUS first then by E5V or D5V,
and the following risks may be encountered:
1. If more than 300 mA current is needed by the board, the PC may be damaged or
current can be limited by PC. As a consequence the board is not powered correctly.
2. 300 mA is requested at the enumeration phase (since JP15 must be OFF), so there is
risk that the request is rejected and the enumeration does not succeed if PC cannot
provide such current. Consequently the board is not powered (LED LD9 remains OFF).
Note: In case the STM32H743I-EVAL board is powered by a USB charger, there is no USB
enumeration, so the led LD9 remains set to OFF permanently and the board is not powered.
Only in this specific case the jumper JP15 needs to be set to ON, to allow the board to be
powered anyway.
The power supply is configured by setting the related jumpers JP9, JP10 and JP11 as
described in Table 3.

A green LED LD10 lights up in one of these cases:
•Power switch (U18) is ON and the STM32H743I-EVAL board works as a USB host
•VBUS is powered by another USB host when the STM32H743I-EVAL board works as a
USB device.
The red LED LD8 lights up when an overcurrent occurs (IVBUS > 500 mA).
Note:1 The STM32H743I-EVAL board should be powered by an external power supply when using
OTG function.
Note:2 JP2 and SB50 must be removed when using USB OTG FS as mentioned in Table 11.
8.10 USB OTG2 HS and FS
The STM32H743I-EVAL Evaluation board supports USB OTG2:
•High-speed communication through a USB Micro-AB connector (CN14), USB
high-speed PHY (U13) for high-speed function
•Full-speed communication through another USB Micro-AB connector (CN16)
The Evaluation board can be powered by these USB connectors (CN14 or CN16) at 5 V DC
with 500 mA current limitation.
As several OTG2 FS signals are shared with the OTG2 HS ULPI bus and USART1, some
PCB reworks are needed when using OTG2 FS (CN16) as shown in Table 9.
A USB power switch (U14) is also connected on VBUS and provides power to either CN14
(with SB27 and SB30 closed and SB28 and SB29 open) or CN16 (with SB28 and SB29
closed and SB27 and SB30 open).
Green LED LD5 (for CN14) or LD7 (for CN16) lights up in one of these cases:
•Power switch (U14) is ON and the STM32H743I-EVAL board works as a USB host.
•VBUS is powered by another USB host when the STM32H743I-EVAL board works as a
USB device.
The red LED LD6 lights up when an overcurrent occurs (IVBUS > 500 mA).
Note: The STM32H743I-EVAL board should be powered by an external power supply when using
OTG function.
8.11 RS232
Communication through RS232 is supported by the D-type, 9-pins connector CN2, which is

8.14 FD-CAN
The STM32H743I-EVAL Evaluation board supports one channel of the Flexible Data Rate
CAN (FD-CAN) communication bus, based on the 3.3 V CAN transceiver.
The standby signal on the FD-CAN transceiver is controlled by PD3 of the STM32H743XI.
Other FD-CAN signals are shared with USB OTG1 FS signals.
8.15 Ethernet
The STM32H743I-EVAL Evaluation board supports 10M/100M Ethernet communication by
a PHY LAN8742A (U5) and integrated RJ45 connector (CN1). Ethernet PHY is connected
to STM32H743XI through the RMII interface.
A 50-M reference clock can be generated by PHY with 25-M crystal or with 25-M MCO from
STM32H743XI. These two resources can be selected by setting jumper JP5 as shown in
Table 12.
8.16 Memories
An 8M x 32-bit SDRAM is connected to the SDRAM bank1 of the FMC interface of the
STM32H743XI microcontroller.
A 1Mx16-bit SRAM is connected to the NOR/PSRAM2 bank1 of the FMC interface and both
8-bit and 16-bit accesses are allowed by BLN0 and BLN1, connected to BLE and BHE of
SRAM respectively.

A 128-Mbit NOR Flash is connected to the NOR/PSRAM1 bank1 of the FMC interface. The
16-bit operation mode is selected by pull-up resistor connected to the BYTE pin of NOR
Flash. The write protection can be enabled or disabled, depending on how the jumper JP13
is set, as showed in Table 13.
All signals for memory are also connected on memory connectors CN11 and CN12 for
memory daughterboards.
Limitations can happen when using other peripherals:
1. FMC addressing limitation depending on number of trace data bus used (A18 max for 4
bit ETM to A21 max for 1 bit ETM)
2. FMC addresses limited to A18 when SAI used
3. FMC addresses limited to A22 when PDM is used
In such cases, serial resistors R236 (A19), R231 (A20), R217 (A21) and R230 (A22) should
be removed. Thus memory addresses A19 to A22 are not connected to FMC and they are
pulled down on the board. Memories can be addressed within a limited address range.
By default, all these serial resistors are soldered on the board. If A19 is required, it is
necessary to configure (SAI_SDB) ADCDAT1 pin of audio codec WM8994ECS/R (U22) by
software to be tri-state.
8.17 Twin Quad-SPI NOR Flash
The Quad-SPI Flash is implemented on the STM32H743XI microcontroller of the Evaluation
board either as 1 Twin Quad-SPI NOR Flash (1-Gbit (2*512Mb)) memory or as 2 Quad-SPI
NOR Flash (512Mb) memories.
The two dies in the Twin Quad-SPI Flash memory share the same clock and chip select
signals of the STM32H743XI microcontroller.
8.18 Analog input
The two-pin header CN5 and 10 K ohm potentiometer RV1 is connected to PA0_C of
STM32H743XI as analog input. A low-pass filter can be implemented by replacing R11 and
C7 with the right value of resistor and capacitor as requested by the end-user application.
8.19 Display and input devices
Four general-purpose-color LEDs (LD 1, 2, 3 and 4) are available as display device. LD1
and LD3 are connected on STM32H743XI, LD2 and LD4 are connected on MFX.
