8.3 Embedded ST_LINK/V2-1
The ST-LINK/V2-1 programming and debugging tool is integrated on the STM32H753I-
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 STM32H753I-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 STM32H753I-EVAL Evaluation board is connected to the PC before the driver is
installed, some STM32H753I-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 STM32H753I-EVAL Evaluation
board and periodically, to stay up-to-date with the latest firmware version.
8.4 Power Supply
The STM32H753I-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 STM32H753I-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 STM32H753I-EVAL board requires 300 mA power from the

Hardware layout and configuration UM2199
14/69 DocID030512 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
STM32H753I-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 STM32H753I-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 STM32H753I-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.
