Note:
Drivers
Before connecting the STM32H7B3I-EVAL board to a Windows PC via USB, the user must install a driver for the
STLINK-V3E (not required for Windows 10). It is available on the www.st.com
website.
In case the STM32H7B3I-EVAL board is connected to the PC before the driver is installed, some STM32H7B3I-
EVAL interfaces may be declared as “Unknown” in the PC device manager. In this case, the user must install the dedicated driver files, and update the driver of the connected device from the device manager as shown in
.
Prefer using the USB Composite Device handle for a full recovery.

Note:
External JTAG, SWD, and trace
Description
There are two basics ways to support an external debug tool. If the user encounters any trouble with the first procedure, then the second one is mandatory.
1.
Keep the embedded STLINK-V3E running. Power on the STLINK-V3E at first until the COM LED lights RED.
Then connect the external Debug tool through connector CN14, CN15, or CN16.
2.
Set the embedded STLINK-V3E in a high impedance state. When the Jumper CN19 (STLK NRST) is ON, the embedded STLINK-V3E is in RESET state and all GPIOs are in high impedance; then the user can connect his external Debug tool on the DEBUG connector CN14, CN15, or CN16 (Refer to
Depending on the design requirement, the embedded STLINK-V3E hardware may be completely disconnected if that is required early in the project.
Figure 5. External debug tools connectors
Remarks:
• It is possible to power the board via CN21 (Embedded STLINK-V3E USB connector) even if an external tool is connected to CN15 (ETM trace connector) or CN14 (External JTAG and SWD connector).
• ETM can only work at 50 MHz clock frequency by default because ETM signals are shared with other peripherals.

Limitations and hardware configuration - JTAG (CN14) or MIPI10 (CN16)
Limitations: STM32H7B3LIH6QU JTAG cannot be connected at the same time to STLINK-V3E and to CN14 or
CN16 connector. To be able to use JTAG on CN14 or CN16 connector, it is necessary to disconnect JTAG signals from STLINK-V3E (JTMS, JTCK, JTDO, and NRST).
To do so, R409, R401, R399, and R398 must be removed.

Board power supply description
The STM32H7B3I-EVAL Evaluation board is designed to be powered from 5 V DC power source. It incorporates a precise polymer Zener diode (Poly-Zen) protecting the board from damage due to the wrong power supply. One of the following six 5 V DC power inputs can be used, upon an appropriate board configuration:
• 5V DC power adapter connected to CN17, the power jack on the board (EXT on the JP29 silkscreen).
This is the default configuration.
5V DC power with 500 mA limitation from CN21, the Micro-B USB connector of STLINK-V3E (STLK on the
JP29 silkscreen). As explained below, if the USB enumeration succeeds, the ST-LINK U5V power is enabled, by asserting the PWR_EN pin. This pin is connected to a power switch U22, which powers the board. This power switch features also a current limitation to protect the PC in case of short-circuit on board.
If overcurrent (More than 600 mA) happens onboard, the LED LD11 is lit.
5V DC power with 500 mA limitation from CN14, the USB OTG HS Micro-AB connector (HS on the HJP29 silkscreen)
5V DC power with 500 mA limitation from CN27, the USB OTG FS Micro-AB connector (FS on the JP29 silkscreen)
5V DC power from CN5 and CN6, the extension connectors for daughterboard (D on the JP29 silkscreen)
5V DC power without limitation from CN21, the Micro-B USB connector of STLINK-V3E (CHGR on the JP29 silkscreen)
The STM32H7B3I-EVAL Evaluation board can be powered from ST-LINK USB connector CN21 (“STLK”), but only the ST-LINK circuit has the power before USB enumeration, for the host PC only provides 100 mA to the boards at that time. During the USB enumeration, the STM32H7B3I-EVAL board asks for the 500 mA power to the Host
PC.
•
•
If the host is able to provide the required power, the enumeration succeeds, the power transistor U22 is switched ON, the green LED LD7 is turned ON, thus the STM32H7B3I-EVAL board is powered and can consume a maximum current of 500 mA current, but not more.
If the host is not able to provide the requested current, the enumeration fails. Therefore, the power switch
(U22) remains OFF, so consequently, 3.3 V domain of the board and MCU are not powered. As a consequence, the green LED LD7 remains turned OFF. In this case, it is mandatory to use an external power supply as an extra power supply.
“EXT” from PSU or “D” can be used as an external power supply in case current consumption of the
STM32H7B3I-EVAL 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, and 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 jumper JP29 to EXT or D side.
2.
Connect the external power source to EXT or D (With mounted daughterboard).
3.
Check green LED LD7 is turned ON.
4.
Connect the PC to USB connector CN21.
If this order is not respected, the board may be powered by VBUS first then “EXT” or “D”, 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
PC. As a consequence, the board is not powered correctly.
2.
500 mA is requested at enumeration, so there is a risk that request is rejected and enumeration does not succeed if PC cannot provide such current. Consequently, the board is not powered and LED LD7 remains
OFF.

Caution: A deadlock occurs if the board SMPS/LDO firmware PWR configuration does not match its hardware configuration: after the reset, the ST-LINK cannot connect the target anymore.
The firmware PWR configuration must be set as follows in function SystemClock_Config in file main.c
:
•
•
If the hardware configuration is Direct SMPS (Default configuration):
HAL_PWREx_ConfigSupply(PWR_DIRECT_SMPS_SUPPLY);
If the hardware configuration is LDO :
HAL_PWREx_ConfigSupply(PWR_LDO_SUPPLY);
If a deadlock occurs because of a mismatch between hardware and firmware PWR settings (SMPS/LDO), the user can recover the board by applying the following procedure:
1.
Power off the board.
2.
Set SW1 (BOOT0) to 1 (system memory).
This changes the BOOT0 pin to 1 instead of 0, thus changing the device boot address to boot address 1 and making the bootloader start in System memory. This avoids starting firmware in the user Flash with a wrong SMPS/LDO configuration versus the hardware board configuration.
UM2662 - Rev 3 page 21/93
6.3.4
3.
Power on the board and connect using STM32CubeProgrammer ( STM32CubeProg ).
4.
Erase the user Flash.
5.
Power off the board and set SW1 to 0.
6.
The board is recovered and can be used normally with matching firmware PWR.

Board power supply - VDDMMC
STM32H7B3I-EVAL can provide either 1.8 V or 3.3 V on VDDMMC power rail of the STM32H7B3LIH6QU microcontroller.
Figure 17. MCU Power: VDDMMC
This power rail can be used in different configurations:
• Default configuration: VDDMMC is forced to 3.3V only.
• SDIO2 configuration: VDDMMC is switched from 3.3 V to 1.8 V if necessary, and it can be powered off.
Default configuration (VDDMMC = 3.3 V only)
Important:
Some pins from STM32H7B3LIH6QU are supplied by VDDMMC, but are '3.3V only' and not linked to SDIO2 (Refer to

).
Three possibilities to force VDDMMC to 3.3V:
1.
Default configuration: Software control (Without hardware modification). In this case, the user must follow the hardware configuration described in
– Set 3V3_SW at 3.3 V by software: 3V3_SW_ENABLE (MFX IO0) = 1 (3V3_SW = ON).
2.
Hardware modification to force 3V3_SW to be 'always ON'. If the user prefers 3V3_SW power supply to be always ON:
– Remove SB34 or set MFX IO0 in high impedance mode (R130 pull-up resistor forces the enable of
U14 LDO).
Remember: In this configuration, the user cannot perform a “power OFF” of 3.3 V supply for SDIO2.
3.
Hardware modification to force VDDMMC to 3.3 V (3V3_AO). If the user wants VDDMMC MCU pin to remain always at 3.3 V without controlling MFX IO0:
– Remove SB14 and fit SB15 in order to connect this pin to the 3V3_AO power supply.
Remember: In this configuration, the user cannot use SDIO2 at 1.8 V.
SDIO2 configuration (VDDMMC = 1V8_SW or 3V3_SW)
3V3_SW, 1V8_SW and VDDMMC are set up in order to allow controlling various use-cases with SDIO2 interface, including power OFF sequence, automatic detection of a UHS1 SD card, and switch from 3.3 V to 1.8 V (Refer to chapter 3.3).

Description
The STM32H7B3I-EVAL Evaluation board supports USB OTG full speed communication via the USB Micro-AB connector CN27 and the USB power switch U29 connected to V
BUS
. The STM32H7B3I-EVAL Evaluation board can be powered by this USB connection at 5 V DC with 500 mA current limitation.
A green LED LD11 is lit in one of these cases:
Power switch (U29) is ON and STM32H7B3I-EVAL works as a USB host
V
BUS
is powered by another USB host when STM32H7B3I-EVAL works as a USB device.
The red LED LD10 is lit when overcurrent occurs (I
VBUS
superior to 500 mA).
The STM32H7B3I-EVAL board must be powered by an external power supply when using the OTG function.
Operating voltage
The STM32H7B3LIH6QU USB OTG FS interface can only be at 3.3 V on this board.
• In host mode, V
BUS
(5 V) is provided by the U29 power switch.
• In device mode, V
BUS
(5 V) is provided by an external source connected to CN27.
Limitations and hardware configuration
Limitation with secondary function FDCAN1:
• As USB FS DP/DM is shared with FDCAN1 RX/TX, SB36 and SB35 must be removed when using USB
OTG FS in order to avoid any stub.

Note: microSD™ card 2
Description
A microSD ™ card connector connected to the SDIO2 3.0 port of STM32H7B3LIH6QU is available on the board.
The microSD ™ card detection is managed by SD_DETECT2 (PI11).
It supports SD 3.0, SDR104, SDR50, DDR50, SDR25, SDR12 and SD 2.0 high-speed (50 MHz) and default speed (25 MHz) modes.
SDIO2 signals are all supplied by VDDMMC. Make sure to supply 3.3 V or 1.8 V on VDDMMC (Refer to
Operating voltage
As SDIO2 is in the VDDMMC domain (VDDMMC = 3.3 V or 1.8 V), when going to UHS1 mode (1.8 V), the
STG4160 switch U2 allows switching signals from 3.3 V to 1.8 V using the SD_LDO_SEL signal (PG6). 3V3_SW and 1V8_SW can also be switched OFF using MFX IO0 and MFX IO8 in case a power-off sequence is needed.

STM32H7B3I-EVAL Evaluation board supports USB OTG high-speed communication via a USB Micro-AB connector CN8, and a USB high-speed PHY U7, connected to STM32H7B3LIH6QU ULPI bus for high-speed function.
USB high-speed PHY (U7) RESETB pin is connected to MFX_GPO5 signal, and can also be connected to NRST if needed by removing SB31 and fitting SB13.
USB high-speed PHY (U7) REFCLK pin is connected to an external 24 MHz oscillator (X3).
The STM32H7B3I-EVAL Evaluation board can be powered by this USB connector (CN8) at 5V DC with 500mA current limitation.
A USB power switch (U39) is also connected to V
BUS
and provides power to CN8 (with SB11 closed). U39 can be enabled with CPEN from U7 with SB12 fitted. It can also be controlled by an MFX GPIO (MFX_GPO4).
Green LED LD6 for CN8 is lit when either:
• The power switch (U39) is ON and STM32H7B3I-EVAL works as a USB host.
• V
BUS
is powered by another USB host when STM32H7B3I-EVAL works as a USB device.
Red LED LD5 is lit when over-current occurs (IV

FMC memory extension connectors CN12 and CN13
FMC memory extension connectors CN12 and CN13
All signals for memory are also connected to memory connectors CN12 and CN13 for memory daughterboards.
Two 40-pin male headers CN12 and CN13 are used to connect with the memory daughterboard. GPIOs which work as FMC memory signals and don’t on CN5 and CN6 are available on these two connectors.
The space between these two connectors is defined as a standard that allows developing common daughterboards. The standard width between CN13 pin1 and CN12 pin1 is 1914 mils (48.62 mm). For signalassignment details, refer to

Daughterboard extension connectors CN5 and CN6
Two 60-pin male headers CN5 and CN6 can be used to connect with a daughterboard or a standard wrapping board to the STM32H7B3I-EVAL Evaluation board. All GPIOs are available on them and memory connectors
(CN12 and CN13).
The space between these two connectors is defined as a standard, which allows developing common daughterboards for several ST evaluation boards. The standard width between CN6 pin1 and CN5 pin1 is
2700 mils (68.58 mm). Each pin on CN5 and CN6 can be used by a daughterboard after disconnecting it from the
corresponding function block on the STM32H7B3I-EVAL Evaluation board. Refer to Table 66

Appendix G
Known limitations of demonstration firmware
Embedded Wizard and Clock&weather: Moving background (moving wave ) behind the main background when the LCD dithering feature is enabled
Touch GFX: Blinds Control - the kitchen and desk icons cannot be unselected once they are already selected
Clock&Weather: Latency when gathering weather data from a remote server
Clock&Weather: API keys are used in each weather API call, so sometimes the user may face a problem when collecting forecast data from the server due to the limited key number used by the application. When facing this problem, ST recommends trying connecting again in order to get forecast data. To use a private key, refer to the user manual STM32CubeH7 demonstration platform ( UM2222 ), section 10.3.4, which explains how to integrate a custom key in the application source code.
Clock&Weather: Display the weather only for a single city instead of three
Clock&Weather: The Forecast weather service provider (OpenWeather map) modifies the data format by introducing new fields. This impacts data collection: city names and temperature values may sometimes be wrong. This issue must be fixed in the next release of the demo.
ST recommends downloading the new binary available on the ST website for users who want to upgrade the demonstration binary.
General: No “Return to Menu Launcher” icon for Touch GFX, STemWin and Embedded Wizard demos
