6.1 Embedded ST-LINK/V2-1
The ST-LINK/V2-1 programming and debugging tool is integrated on the
STM32F746G-DISCO discovery board. Compared to ST-LINK/V2 the changes are listed
below.
The new features supported on ST-LINK/V2-1 are:
• USB software reenumeration
• Virtual Com port interface on USB
• Mass storage interface on USB
• USB power management request for more than 100 mA power on USB
These features are no more supported on ST-LINK/V2-1:
• SWIM interface
• Application voltage lower than 3 V
For all general information concerning debugging and programming features common
between V2 and V2-1 refer to ST-LINK/V2 in-circuit debugger/programmer for STM8 and
STM32 User manual (UM1075).
6.1.1 Drivers
The ST-LINK/V2-1 requires a dedicated USB driver, which, for Windows XP, 7 and 8, can be
found at www.st.com.
In case the STM32F746G-DISCO discovery board is connected to the PC before the driver
is installed, some STM32F746G-DISCO interfaces may be declared as “unknown” in the PC
device manager. In this case the user must install the driver files, and update the driver of
the connected device from the device manager.
Note: Prefer using the “USB Composite Device” handle for a full recovery.

6.1.2 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 functionality, bug fixes, support for new microcontroller families), it is
recommended to visit www.st.com before starting to use the STM32F746G-DISCO board
and periodically, in order to stay up-to-date with the latest firmware version.
6.2 Power supply
The STM32F746G-DISCO discovery board is designed to be powered by 5V DC power
supply. It is possible to configure the discovery board to use any of the following five sources
for the power supply:
• 5V DC power adapter connected to JP2 (external power supply on silkscreen of JP1
(5V ext)). In this case, the STM32F746G-DISCO discovery board must be powered by
a power supply unit or by an auxiliary equipment complying with the standard
EN-60950-1: 2006+A11/2009, and must be Safety Extra Low Voltage (SELV) with
limited power capability.
Figure 7. JP1 (5V ext) from JP2 (5V)
• 7-12V DC power from CN6 pin named Vin on silkscreen, the extension connectors for
Arduino UNO shields or daughterboard (external power source on silkscreen of JP1
(5V ext)).

UM1907 Hardware layout and configuration
• 5V DC power with limitation from CN14, the USB type mini-B connector of
ST-LINK/V2-1 (USB 5V power source on silkscreen of JP1 (5V link)). It is the default
setting. If the USB enumeration succeeds (as explained below), the ST-LINK 5V link
power is enabled, by asserting the PWR_ENn signal. This pin is connected to a power
switch (ST890), which powers the board. This power switch features also a current
limitation to protect the PC in case of a short-circuit on the board (more than 600 mA).
The STM32F746G-DISCO discovery board can be powered from the ST-LINK USB
connector CN14 (5V link), but only the ST-LINK circuit has the power before USB
enumeration, because the host PC only provides 100
the USB enumeration, the STM32F746G-DISCO board asks for the 500
mA to the board at that time. During
mA power to the
host PC. If the host is able to provide the required power, the enumeration ends by a
“SetConfiguration” command and then, the power transistor U8 (ST890) is switched ON, the
red LED LD2 is turned ON, thus the STM32F746G-DISCO board can consume no more
than 500
mA of current. If the host is not able to provide the requested current, the
enumeration fails. Therefore the ST890 (U8) remains OFF and the STM32 part including the
extension board will not be powered. As a consequence the red LED LD2 remains turned
OFF. In this case it is mandatory to use an external power supply.
Figure 9. JP1 (5V link)
Note: In case the board is powered by a USB charger, there is no USB enumeration, so the led
LD2 remains set to OFF permanently and the board is not powered. Only in this specific
case, the resistor R109 needs to be soldered, to allow the board to be powered anyway.
The LED LD2 is lit when the STM32F746G-DISCO discovery board is powered by the 5V
correctly.
Caution: Do not connect the PC to the ST-LINK (CN14) when R109 is soldered. The PC may be
damaged or the board not powered correctly.

• 5V DC power with 500 mA limitation from CN13, the USB OTG FS micro-AB connector
(USB 5V power source on silkscreen of JP1 (usb_fs)).

• 5V DC power with 500 mA limitation from CN12, the USB OTG HS micro-AB connector

Figure 11. JP1 (usb_hs)
6.3 Programming/debugging when the power supply is not from ST-LINK (5V link)
It is mandatory to power the board first using JP1 (5V ext) or (usb_hs) or (usb_fs), 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 the jumper JP1 on (5V ext) or (usb_hs) or (usb_fs)
2. Connect the external power source to JP2 or CN6 or CN12 or CN13
3. Check the red LED LD2 is turned ON
4. Connect the PC to USB connector CN14
If this order is not respected, the board may be powered by VBUS first from ST-LINK, and
the following risks may be encountered:
14/49 DocID027942 Rev 3
Page 15
UM1907 Hardware layout and configuration
1. If more than 500 mA current is needed by the board, the PC may be damaged or
current can be limited by the PC. As a consequence the board is not powered correctly.
2. 500 mA will be requested at the enumeration, so there is a risk that the request is
rejected and enumeration does not succeed if the PC cannot provide such current.
6.4 Clock sources
Up to 3 clock sources as described below:
• X1, 24 MHz oscillator for the USB OTG HS PHY and camera module (daughterboard)

1. By default OTG_FS_VBUS is driven by the software and not by the alternate function of the
STM32F746NGH6 (R64 = ON, R63 = OFF, R58 = ON and PA9 = VCP_TX (Virtual Com Port) and PJ12 =
OTG_FS_VBUS).
To use the alternate function OTG_FS_VBUS of the STM32F746NGH6, it is needed to have: R64 = OFF,
R63 = ON, R58 = OFF. In this configuration, VCP_TX is no longer available and PA9 = OTG_FS_VBUS,
PJ12 = not connected.
