8.3 Embedded ST-LINK/V2-1

The ST-LINK/V2-1 programming and debugging tool is integrated on the 32F746GDISCOVERY 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).

8.3.1 Drivers

Before connecting the 32F746GDISCOVERY board to a Windows® PC (XP, 7, 8 and 10) through the USB, a driver for the ST-LINK/V2-1 must be installed. It is available at the www.st.com website. In case the STM32 Discovery is connected to the PC before the driver is installed, some Discovery interfaces may be declared as “Unknown” in the PC device manager. To recover from this situation, after installing the dedicated driver, the association of “Unknown” USB devices found on the 32F746GDISCOVERY board to this dedicated driver, must be updated in the device manager manually.

Note: It is recommended to proceed by using USB Composite Device, as shown in Figure 7.

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 functionality, bug fixes, support for new microcontroller families), it is recommended to visit the www.st.com website before starting to use the 32F746GDISCOVERY board and periodically, to stay up-to-date with the latest firmware version.

8.4 Power supply

The 32F746GDISCOVERY 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 32F746GDISCOVERY 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 (see Figure 8).

Figure 8. 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)), see Figure 9.

• 5V DC power with limitation from CN14, the USB Type-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 32F746GDISCOVERY 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 mA to the board at that time. During the USB enumeration, the 32F746GDISCOVERY 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 “SetConfiguration” command and then, the power transistor U8 (ST890) is switched ON, the red LED LD2 is turned ON, thus the 32F746GDISCOVERY 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 (see Figure 10).

Figure 10. 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 32F746GDISCOVERY 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)), see Figure 11.

Figure 11. JP1 (usb_fs)

• 5V DC power with 500 mA limitation from CN12, the USB OTG HS Micro-AB connector (USB 5V power source on silkscreen of JP1 (usb_hs)), see Figure 12.

Figure 12. JP1 (usb_hs)

8.5 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 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 Discovery board may be powered by VBUS first from ST-LINK, and the following risks may be encountered:

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.

8.6 Clock sources

Up to 3 clock sources as described below:

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

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

• X3, 32 KHz crystal for the STM32F746NGH6 embedded RTC

8.7 Reset sources

The reset signal of 32F746GDISCOVERY Discovery board is active low and the reset sources include:

• Reset button B2

• Arduino Uno shield board from CN6

• Embedded ST-LINK/V2-1

8.8 Audio

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

• The analog line input is connected to the ADC of WM8994ECS/R through the blue audio jack CN11.

• The analog line output is connected to the DAC of WM8994ECS/R via the 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 32F746GDISCOVERY Discovery board. They are connected to the input digital microphones of WM8994ECS/R.

• One coaxial connector CN1 is implemented on 32F746GDISCOVERY to receive external audio data compatible with the SPDIF specification.

8.9 USB OTG FS

The 32F746GDISCOVERY Discovery board supports USB OTG full speed communication via a USB Micro-AB connector (CN13) and a USB 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 32F746GDISCOVERY works as an USB host

• VBUS is powered by another USB host when 32F746GDISCOVERY works as an USB device.

The red LED LD6 will be lit when an overcurrent occurs.

Note: 32F746GDISCOVERY board should be powered by an external power supply when using OTG function.

8.10 USB OTG HS

The 32F746GDISCOVERY Discovery board supports the USB OTG high speed communication via a 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.

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 32F746GDISCOVERY works as a USB host

• VBUS is powered by another USB host when 32F746GDISCOVERY works as a USB device.

The red LED LD3 will be lit when an overcurrent occurs.

Note: The 32F746GDISCOVERY board should be powered by an external power supply when using OTG function.

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.
