1.1 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 re-enumeration

• Virtual Com port interface on USB

• Mass storage interface on USB

• USB power management request for more than 100mA 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 please refer to ST-LINK/V2 user manual (UM1075).

1.1.1 Drivers

The ST-LINK/V2-1 requires a dedicated USB driver, which can be found on www.st.com for Windows 7 and 8. On Windows XP the ST-LINK/V2-1 driver requires WinUsb to be installed before using the ST-LINK/V2-1 (either available from Microsoft website or included in the USB driver for ST-LINK/V2 for XP).

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.


10/46 DocID027942 Rev 1

1.1.2 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.

1.2 Power supply

STM32F746G-DISCO discovery board is designed to be powered by 5V DC power supply. It’s 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)).

Figure 6. 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)).

Figure 7. JP1 (5V ext) from CN6 (Vin)

DocID027942 Rev 1 11/46

• 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 board (more than 600mA).

STM32F746G-DISCO discovery board can be powered from ST-LINK USB connector CN14 (5V link), but only ST-LINK circuit has the power before USB enumeration, because the host PC only provides 100mA to the board at that time. During the USB enumeration, STM32F746G-DISCO board asks for the 500mA power to the host PC. If the host is able to provide the required power, the enumeration finishes by a “SetConfiguration” command and then, the power transistor U8 (ST890) is switched ON, the red LED LD2 is turned ON, thus STM32F746G-DISCO board can consume maximum 500mA current, but no more. If the host is not able to provide the requested current, the enumeration fails. Therefore the ST890 (U8) remains OFF and the MCU part including the extension board won’t 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 8. JP1 (5V link)

Note: In case the board is powered by an 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 PC to ST-LINK (CN14) when R109 is soldered. PC may be damaged or the board not powered correctly.

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

Figure 9. JP1 (usb_fs)

• 5V DC power with 500mA limitation from CN12, the USB OTG HS micro-AB connector (USB 5V power source on silkscreen of JP1 (usb_hs)).

Figure 10. JP1 (usb_hs)

1.3 Programing/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:

DocID027942 Rev 1 13/46


45

1. If more than 500mA 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. 500mA will be requested at the enumeration, so there is a risk that the request is rejected and enumeration does not succeed if PC can’t provide such current.

1.4 Clock sources

Up to 3 clock sources as described below:

• X1, 24MHz oscillator for USB OTG HS PHY and camera module (daughterboard)

• X2, 25MHz oscillator for STM32F746NGH6 microcontroller and Ethernet PHY.

• X3, 32KHz crystal for STM32F746NGH6 embedded RTC

1.5 Reset sources

The reset signal of STM32F746G-DISCO discovery board is active low and the reset sources include:

• Reset button B2

• Arduino Uno shield board from CN6

• Embedded ST-LINK/V2-1

1.6 Audio

An audio codec WM8994ECS/R from CIRRUS with 4 DACs & 2ADCs is connected to SAI interface of STM32F746NGH6. It communicates with STM32F746NGH6 via I2C bus shared with the camera module and I2C 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 DAC 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 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.

1.7 USB OTG FS

STM32F746G-DISCO discovery board supports USB OTG full speed communication via a USB micro-AB connector (CN13) and USB power switch (U6) connected to VBUS. The discovery board can be powered by this USB connection at 5V DC with 500mA current limitation.


14/46 DocID027942 Rev 1

A green LED LD5 will be lit in one of these cases:

• Power switch (U6) is ON and STM32F746G-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 over-current occurs.

Note: STM32F746G-DISCO board should be powered by external power supply when using OTG function.

1.8 USB OTG HS

STM32F746G-DISCO discovery board supports USB OTG high speed communication via an USB micro-AB connector (CN12), USB high speed PHY (U15) USB3320C-EZK from MICROCHIP for high speed function.

The discovery board can be powered by the USB connectors (CN12) at 5V DC with 500mA current limitation.

An USB power switch (U7) is also connected on VBUS and provides power to CN12.

The green LED LD4 will be lit when either:

• Power switch (U17) is ON and STM32F746G-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 over-current occurs.

Note: STM32F746G-DISCO board should be powered by external power supply when using OTG function.

1.9 MicroSD card

1. By default OTG_FS_VBUS is driven by 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's needed to have: R64 = OFF, R63 = ON, R58 = OFF. In that configuration, VCP_TX is no longer available and PA9 = OTG_FS_VBUS, PJ12 = not connected.
