5.1 Embedded ST-LINK/V2-1
The ST-LINK/V2-1 programming and debugging tool is embedded on the STM32756G-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 100 mA 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 ST-LINK/V2 and ST-LINK/V2-1 refer to ST-LINK/V2 User Manual UM1075.

Note: ETM can only work at 50 MHz clock by default, because ETM signals are shared with other peripherals. If a better performance of ETM is required (84 MHz/98 MHz), R31, R34, R35, R37, R39, R247, SB4, SB16, SB18 must be removed, to reduce the stub on ETM signals. In this configuration SAI, Ethernet and Camera are not functional and Nor Flash memory and SRAM addresses are limited on A18.
5.1.1 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 STM32756G-EVAL evaluation board is connected to the PC, before the driver is installed, some STM32756G-EVAL 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.

5.1.2 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 functionalities, bug fixes, support for new microcontroller families), it is recommended to visit www.st.com before starting to use the STM32756G-EVAL board and periodically, in order to stay up-to-date with the latest firmware version.

5.2 Power supply
STM32756G-EVAL evaluation board is designed to be powered by 5 V DC power supply and it is protected by PolyZen from wrong power plug-in event. 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 on the board to the power jack CN17, the power jack on the board (Power Supply Unit on silk screen of JP13(PSU)). This is default setting of power supply source selection on STM32756G-EVAL evaluation board.
5 V DC power with 300 mA limitation from CN21, the USB type B connector of ST-LINK/V2-1 (USB 5 V power source on silkscreen of JP13(STlk)). If the USB enumeration succeeds (as explained below), the ST-LINK/V2-1 U5V power is enabled, by asserting the PWR_EN pin. 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 short-circuit on board. If an overcurrent (more than 600 mA) happens on the board, the LED LD11 is lit. This setting cannot be used as default power source selection, because the whole board power consumption will be larger than the current limitation of DC power from CN21.
5V DC power with 500 mA limitation from CN8, the USB OTG HS Micro-AB connector (USB 5V power source on silkscreen of JP13 (HS)).
5V DC power with 500 mA limitation from CN13, the USB OTG FS1 Micro-AB connector (USB 5V power source on silkscreen of JP13 (FS1)).
5V DC power with 500 mA limitation from CN14, the USB OTG FS2 Micro-AB connector (USB 5V power source on silkscreen of JP13 (FS2)).
5V DC power from CN5 and CN6, the extension connectors for daughterboard (daughterboard power source on silkscreen of JP13 (D5V)).
STM32756G-EVAL evaluation board can be powered from ST-LINK/V2-1 USB connector CN21 (U5V), only when the 5.7" LCD is disconnected, otherwise power consumption exceeds 300mA. When the board is connected to USB port only the ST-LINK/V2-1 is powered for the USB enumeration, because host PC only provides 100 mA max to the board at that time. During the USB enumeration, STM32756G-EVAL board requires 300 mA power from the host PC. If the host PC is able to provide the required power, the enumeration succeeds and the power transistor U17 (ST890) is switched ON, the red LED LD10 is turned ON, thus STM32756G-EVAL evaluation board can consume no more than 300 mA of current. If the host PC is not able to provide the requested current, the enumeration fails. Therefore the ST890 (U17) remains OFF so consequently 3.3 V domain of the board and MCU will not be powered. As a consequence, the red LED LD10 remains turned OFF. In this case it is mandatory to use an external power supply as extra power supply.
E5V (from PSU) or D5V must be used as external power supply, in case current consumption of STM32756G-EVAL evaluation board exceeds the allowed current on USB. In this condition it is still possible to use USB for communication, for programming or debugging only, but it is mandatory to power the board, first using E5V or D5V, then connecting the USB cable to the PC. Proceeding this way ensures that the enumeration succeeds, thanks to the external power source.
DocID027919 Rev 1 13/79
UM1903 Hardware layout and configuration

The following power sequence procedure must be respected:
Connect jumper JP13 for PSU or D5V side
Check that JP15 is removed
Connect the external power source to PSU or D5V (daughterboard mounted)
Check red LED LD10 is turned ON
Connect the PC to USB connector CN21
If this order is not respected, the board may be powered by VBUS first then 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 will be requested at enumeration (since JP15 must be OFF), so there is risk that request is rejected and enumeration does not succeed if the PC cannot provide such current. Consequently the board is not powered (the led LD10 remains OFF).
Note: In case the board is powered by an USB charger, there is no USB enumeration, so the led LD10 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 but in any cases the current will be limited to 600 mA by U17 (ST890).
The power supply is configured by setting the related jumpers JP2, JP9 and JP13 as described in Table 1.

memory. The write protection can be enabled or disabled, depending on setting of jumper JP10, as showed inside Table 12.
All signals for memory are also connected on memory connectors CN10 and CN11 for memory daughterboards.
Some limitation can happen when using other peripherals:
1. FMC addressing limitation depending number of Trace data bus used (A18 max for 4 bit ETM to A21 max for 1 bit ETM)
2. FMC addresses limited to A21 when SAI used
3. FMC addresses limited to A20 when Camera is used
4. FMC addresses limited to A22 when Ethernet is used
In such cases, memory addresses A19 to A22 not connected to FMC, are pulled down, so that memories can be addressed within a limited address range. If A21 or A22 is required, the camera board should be removed on the board.

5.19 Motor control
STM32756G-EVAL evaluation board supports both asynchronous and synchronous three-phases brushless motor control via a 34 pins connector CN1, which provides all required control and feedback signals to and from motor power-driving board.
The available signals on this connector are emergency stop, motor speed, 3 phases motor current, bus voltage, heatsink temperature, coming from the motor driving board and 6 channels of PWM control signal, going to the motor driving circuit.
Some PCB reworks are needed for motor control application, to disconnect those peripherals, which share I/Os with motor control connector and connect these I/Os to motor control connector:
