1.4 Delivery recommendationsSeveral verifications are needed before using the board for the first time to make sure that nothing has been damaged during shipment and no components are unplugged and lost.
When the board is extracted from its plastic bag, please check that no component remains in the bag. Main components to verify are:
1. The 25MHz crystals (X1 and X4) may have been removed by a shock.
2. The camera connected on socket CN15 located on the right side of the board under the JTAG connector may be unplugged. If this is the case, please refer to the note in Section 2.18: Camera module to make sure to replug it in the correct position.
3. The MicroSD card may have been ejected from its connector CN6 (top left corner of the board).
The plastic protection on the camera should be removed carefully as the connection is very fragile.

2.9 Motor controlSTM3240G-EVAL evaluation board enables a three-phase brushless motor control via a 34- pin connector (CN5), which provides all required control and feedback signals to and from the motor power-driving board. Available signals on this connector include emergency stop, motor speed, 3-phase 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.
The solder bridge (SB18) allows to choose two kinds of synchronization methods for PFCs (Power Factor Correction) while the SB17 can be set for different signals on pin 31 of CN5.
The I/O pins used on motor control connector CN5 are multiplexed with some peripherals on the board; either motor control connector or multiplexed peripherals can be enabled by the setting of solder bridges SB10, SB11, SB12, SB14, SB15 and SB16.

Smartcard shares some I/Os with I2S bus for Audio. Some jumper settings need to be reconfigured to enable smartcard as indicated below:
2.11 MicroSD cardThe 1 GByte or more MicroSD card connected to SDIO of STM32F407IGH6 is available on the board. MicroSD card detection is managed by the standard I/O port PH13. MicroSD card shares I/Os with motor control, RS-232 and audio. The jumpers JP22 and JP16 must be refit and motor control connector (CN5) must be disconnected for MicroSD card function.
2.12 MEMSA ST MEMS device LIS302DL is connected to I2C1 bus of STM32F407IGH6 on the board.
2.13 PotentiometerThere is one 10K ohm potentiometer RV1 connected to PF9 of STM32F407IGH6 on the board.
2.14 ADCTwo test points (TP3 AIN-) and (TP4 AIN+) are placed close to port PC1 of the MCU allowing precise measurements on ADC1, ADC2 or ADC3 channel 11. As PC1 is also used as current A input on the motor control connector it is recommended to remove R219 to optimize noise immunity on this input.
A potentiometer RV1 is connected to PF9 of STM32F407IGH6. If needed, a low pass filter (R74 and C59) can be placed on this input to reduce the bandwidth of the analog input PF9.
It is also possible to place the Ethernet PHY (U5) in low power mode in order to reduce the noise induced by this high frequency peripheral. Power down pin (MII_INT in the schematic) is connected to PB14 of the MCU, so this I/O can be configured as output low during analog precision measurement.

Note: 1 A test point (TP2) is available on the board for the PTP_PPS feature test.
2 The Ethernet PHY (U5) can be powered down by regulating PB14.
3 In RMII mode it is not possible to use MCO to output the 50 MHz clock to PHY due to the PLL limitation explained in chapter 2.6.5 of STM32F20x & STM32F21x Errata sheet (ES0005). In such a case it is possible to provide the 50 MHz clock by soldering a 50 MHz oscillator (ref SM7745HEV-50.0M or equivalent) on the U3 footprint located under CN3 and also removing jumper on JP5. This oscillator is not provided with the board.

2.17 USB OTG HSThe STM3240G-EVAL evaluation board enables USB OTG high speed communication via a USB Micro-AB connector (CN9), USB high speed PHY (U8) and USB power switch (U4) connected to VBUS. The evaluation board can be powered by this USB connector (CN9) at 5V DC with a 500 mA current limitation.
The LED LD7 indicates that power switch (U4) is ON and STM3240G-EVAL is working as a USB host or that VBUS is powered by another USB host when STM3240G-EVAL is working as a USB device. The LD8 indicates an over-current.
The USB ULPI bus is shared with CAN2 bus, the JP10 and JP3 must be kept open for USB OTG HS.
Note: On boards MB786 prior to version B03 it is possible that after a board RESET the MCU is no longer able to control communication with the OTG PHY (U8). When this issue occurs the only way to recover OTG PHY control is to power the board OFF and ON. This issue is fixed on MB786 version B03 or newer.

2.18 Camera moduleA camera module is connected to DCMI bus of STM32F407IGH6 and shares the same I/Os with the motor control connector. SB16 must be kept open for camera module application.
There are two possible modules and omnivision cameras populated on the CN15 connector of the board:
● 1.3 Megapixel: Module CN01302H1045-C: Camera OV9655
● 2 Megapixel: Module CN020VAH2554-C: Camera OV2640
Note: 1 When the camera demo loaded in Flash is executed, some green pixels may appear in high contrast zones, depending on the image captured.
2 The camera is not firmly restricted on its connector (CN15). It is possible that during shipment the camera could be unplugged. In such case you need to plug it into the right position as shown on the picture below (pin 1 dot on top left corner of the socket).
It is not recommended to remove it in order to avoid false contact later.

2.20 Development and debug supportVersion 2 of the ST-LINK, called ST-LINK/V2, is embedded on the board. This tool allows onboard program loading and debugging of the STM32F using the JTAG or SWD interface. Third-party debug tools are also supported by the JTAG (CN14) or Trace (CN13) connectors.
To communicate with the embedded ST-LINK/V2, a specific driver needs to be installed on your PC. To download and install this driver, refer to the software and development tools page for the STM32F family available on www.st.com (the install shield is called ST-LINK_V2_USBdriver.exe).
Third-party toolchains, Atollic TrueSTUDIO, KEIL ARM-MDK, IAR EWARM and Tasking VX-Toolset support ST-LINK/V2 according to the following table:
The embedded ST-LINK/V2 connects to the PC via a standard USB cable from connector CN21. The bicolor LED LD10 (COM) indicates the status of the communication as follows:
● Slow blinking Red/Off: At power-on before USB initialization
● Fast blinking Red/Off: After the first correct communication between PC and ST-LINK/V2 (enumeration)
● Red LED On: When initialization between PC and ST-LINK/V2 is successfully finished
● Green LED On: After successful target communication initialization
● Blinking Red/Green: During communication with target
● Green On: Communication finished and OK
● Orange On: Communication failure
Note: It is possible to power the board via CN21 (embedded ST-LINK/V2 USB connector) even if an external tool is connected to CN13 (trace) or CN14 (external JTAG and SWD).
