® Before connecting the STM32H743I-EVAL Evaluation board to a Windows PC (XP, 7, 8 or 10) through a USB, a driver for the ST-LINK/V2-1 must be installed. It is available at the www.st.com website. In case the STM32H743I-EVAL Evaluation board is connected to the PC before the driver is installed, some STM32H743I-EVAL interfaces may be declared as "unknown"...
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...

Consequently the board is not powered (LED LD9 remains OFF). Note: In case the STM32H743I-EVAL board is powered by a USB charger, there is no USB enumeration, so the led LD9 remains set to OFF permanently and the board is not powered.
Default setting: Fitted JP10 is used to select one of the six possible power supply resources. To supply the STM32H743I-EVAL board through the USB connector of the ST- LINK/V2-1 (CN23) set JP10 as shown to the right: (default setting) To supply the STM32H743I-EVAL board through the jack (CN10), set JP10 as...

Note: For Ethernet clock and jumper JP5 configuration refer to Section 8.15. Reset sources The reset signal of STM32H743I-EVAL Evaluation board is low active and the reset sources include: • Reset button B1 • Debugging tools from JTAG/SWD connector CN9 and ETM trace connector CN8 •...
PDM port of the STM32H743XI, by setting the switch SW2 shown in Table 8. The coupon connectors CN25 and CN26 can be used to support ST-MEMS microphone STEVAL- MKI129V1 after removing SB54 and SB55 solder bridges. 18/69 DocID030511 Rev 1 Arrow.com.
SAI_CLK to PG7. USB OTG1 FS The STM32H743I-EVAL Evaluation board supports USB OTG1 full-speed communication through a USB Micro-AB connector (CN18) and USB power switch (U18) connected to . The Evaluation board can be powered by this USB connection at 5 V DC with 500 mA current limitation.
A green LED LD10 lights up in one of these cases: • Power switch (U18) is ON and the STM32H743I-EVAL board works as a USB host • is powered by another USB host when the STM32H743I-EVAL board works as a USB device.
8.13 External I C connector The I2C1 bus of the STM32H743XI is connected to CN4 on the STM32H743I-EVAL. The C functional daughterboard can be mounted on the CN4 connector and accessed by the microcontroller through the I2C1 bus. DocID030511 Rev 1 21/69 Arrow.com.
UM2198 8.14 FD-CAN The STM32H743I-EVAL Evaluation board supports one channel of the Flexible Data Rate CAN (FD-CAN) communication bus, based on the 3.3 V CAN transceiver. The standby signal on the FD-CAN transceiver is controlled by PD3 of the STM32H743XI.
UM2198 Hardware layout and configuration A 128-Mbit NOR Flash is connected to the NOR/PSRAM1 bank1 of the FMC interface. The 16-bit operation mode is selected by pull-up resistor connected to the BYTE pin of NOR Flash. The write protection can be enabled or disabled, depending on how the jumper JP13 is set, as showed in Table Table 13.
Hardware layout and configuration UM2198 The 4-direction joystick (B4) with selection, Wakeup (B2) and Tamper/key button (B3) are available as input devices. 5.7” 640x480 TFT color LCD with capacitive touch panel is connected to the RGB LCD interface of the STM32H743XI microcontroller. Table 14.
