6.1 Embedded ST-LINK/V2-1
The ST-LINK/V2-1 programming and d
ebugging 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).
The ST-LINK/V2-1 requires a dedicated USB dr
iver, 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 inst
all 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 th
e life time of the ST-LINK/V2-1 product (for
example new functionality, bug fixes, suppo
rt for new microcontro
ller families), it is
recommended to visit
www.st.com
before starting to use the STM32F746G-DISCO board
and periodically, in order to stay up-t
o-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 (ext
ernal 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 complyi
ng with the standard
DocID027942 Rev 313/49
UM1907Hardware 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
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 ho
st PC only provides 100
mA to the board at that time. During
the USB enumeration, the STM32F746G-DISCO board asks for the 500
mA power to the
host PC. If the host is able to provide the required power, the enumeration ends by a
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 LE
D 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 char
ger, 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-DISC
O 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.

6.3 Programming/debugging when
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. Proceed
ing this way ensures that the enumeration
succeeds thanks to the ex
ternal 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:
DocID027942 Rev 315/49
UM1907Hardware 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 source
s as described below:
X1, 24 MHz oscillator for the USB OTG HS
PHY and camera modu
X2, 25 MHz oscillator for the STM32F746
An audio codec WM8994ECS/R from CIRRUS wi
th 4 DACs and 2ADCs is connected to SAI
interface of STM32F746N
GH6. It communicates with STM32F746NGH6 via I
C bus shared
with the camera module and I
C extension connector.
The analog line input is connected to ADC of WM8994ECS/R through blue audio jack
CN11.
The analog line output is connected to DA
C of WM8994ECS/R via green audio jack
CN10.
Two external speakers can be connected to WM8994ECS/R via JP3 for right speaker
and JP4 for left speaker.
Two digital microphones (ST MEMs microphone) MP34DT01TR are on the
STM32F746G-DISCO discovery board. They are connected to the input digital
microphones of WM8994ECS/R.
One coaxial connector CN1 is implemented on STM32F746G-DISCO to receive
external audio data compatible with SPDIF specification.

6.7 USB OTG FS
The STM32F746G-DISCO discovery board supports USB OTG full speed communication
via a USB micro-AB connector (CN13) and U
SB power switch (U6) connected to VBUS.
The discovery board can be powered by this USB connection at 5V DC with 500mA current
limitation.
A green LED LD5 will be lit
in one of these cases:
Power switch (U6) is ON and STM
32F746G-DISCO works as an USB host
VBUS is powered by another USB host when STM32F746G-DISCO works as an USB
device.
The red LED LD6 will be lit when an overcurrent occurs.
Note:STM32F746G-DISCO board should be powere
d by an external power supply when using
OTG function.
6.8 USB OTG HS
The STM32F746G-DISCO discovery board supports the USB OTG high speed
communication via a USB micro-AB connector (CN12), USB high speed PHY (U15)
USB3320C-EZK from MICROCHI
P for high speed function.
The discovery board can be powered by the USB connectors (CN12) at 5V DC with 500mA
current limitation.
A USB power switch (U7) is also connected on VBUS and provides power to CN12.
The green LED LD4 will be lit
in one of these cases:
Power switch (U17) is ON and STM32F
746G-DISCO works as an USB host
VBUS is powered by another USB host when STM32F746G-DISCO works as an USB
device.
The red LED LD3 will be lit when an overcurrent occurs.
Note:STM32F746G-DISCO board should be powere
d by an external power supply when using
OTG function.
6.9 microSD card
The 2-Gbyte (or more) microSD card connected to the SDMMC1 port of the

1.By default OTG_FS_VBUS is driven by the soft
ware 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, VC
P_TX is no longer available and PA9 = OTG_FS_VBUS,
