Description

There are two different ways to program or debug the onboard STM32 MCU:

•

Using the embedded STLINK-V3E

Using an external debug tool connected to CN8 MIPI-10 connector

The facility for programming and debugging the STM32H7B3LIH6Q is integrated into the STM32H7B3I-DK board.

The STLINK-V3E makes the STM32H7B3I-DK board Mbed Enabled™.

The embedded STLINK-V3E supports only SWD and VCP for STM32 devices. For information about debugging and programming features, refer to the technical note Overview of ST-LINK derivatives ( TN1235 ), which describes in detail all the STLINK-V3E features.

Features supported on STLINK-V3E:

5V power supplied by USB connector (CN14)

USB 2.0 high-speed-compatible interface

JTAG/serial wire debugging (SWD) specific features:

– 3 to 3.6V application voltage on the JTAG/SWD interface and 5V tolerant inputs

– JTAG

– SWD and serial viewer (SWV) communication

STDC14 (MIPI10) compatible connector (CN8)

Status COM LED (LD4) which blinks during communication with the PC

Fault red LED (LD7) alerting on USB overcurrent request

5V/500mA output power supply capability (U24) with current limitation and LED

Green LED ON: 5V enabled (LD5)

Drivers

Before connecting the STM32H7B3I-DK 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-DK board is connected to the PC before the driver is installed, some STM32H7B3I-DK interfaces may be declared as Unknown in the PC device manager. In this case, the user must manually install the dedicated driver files, and update the driver of the connected device from the device manager as shown in

Figure 8

Prefer using the USB Composite Device handle for a full recovery.

Embedded STLINK-V3E

STLINK-V3E firmware upgrade

The STLINK-V3E embeds a firmware upgrade mechanism for in-situ upgrades through the USB port. As the firmware may evolve during the lifetime of the STLINK-V3E product (for example new functionalities, bug fixes, support for new microcontroller families), it is recommended to visit the www.st.com

website before starting to use the STM32H7B3I-DK Discovery kit and periodically, to stay up-to-date with the latest firmware version.

Using an external debug tool to program and debug the onboard STM32

There are two basic ways to support an external debug tool:

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 CN8 STDC14/MIPI-10 debug connector.

Set the embedded STLINK-V3E in a high impedance state. When setting the CN13 jumper (STLK_RST)

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 to the CN8 debug connector.

Power supply

•

The STM32H7B3I-DK Discovery kit is designed to be powered by a 5 V DC power source.

One of the following 5 V DC power inputs can be used, upon an appropriate board configuration:

A host PC connected to CN14 through a USB Micro-B cable with enumeration (default setting)

An external charger connected to CN14 through a USB Micro-B cable (without enumeration)

An external 7-12V power supply connected to CN19 pin 8 (ARDUINO ® )

A host PC connected to CN15 through a USB Micro-AB cable (5V_USB_HS)

An external 5V power supply connected to CN2 (E5V)

The LD5 green LED turns ON when the voltage on the power line marked 5V is present. All supply lines required for the operation of the components on the STM32H7B3I-DK are derived from that 5V line.

The Discovery board must be powered by a power supply unit, or by auxiliary equipment complying with the standard EN-60950-1: 2006+A11/2009, and must be Safety Extra Low Voltage (SELV) with limited power capability.

Supplying the board through STLINK-V3E USB connector 5 V / 500 mA

The STM32H7B3I-DK Discovery kit can be powered from the STLINK-V3E connector CN14, by placing a jumper between pins 1 and 2 of JP1 “STLK”. This is the default setting.

If the USB enumeration succeeds, the 5V_ST_LINK power is enabled, by asserting the PWR_ENn signal from

STM32F723IEK6 “STLINK V3” (U18). This pin is connected to a power switch STMPS2151STR (U24), which powers the board. The power switch STMPS2151STR (U24) features also a current limitation to protect the PC in case of a short-circuit on the board. If an overcurrent (more than 500mA) occurs onboard, the RED LED LD7 is lit.

The STM32H7B3I-DK board with its shield can be powered from the STLINK-V3E USB connector CN14, but only

ST-LINK circuit gets power before USB enumeration because the host PC only provides 100mA to the board at that time.

During the USB enumeration, the STM32H7B3I-DK board asks for 500mA power to the host PC.

•

If the host can provide the required power, the enumeration finishes by a SetConfiguration command, and then, the power switch STMPS2151STR is switched ON, the Green LED LD5 is turned ON, thus the

STM32H7B3I-DK board and its shield on it can consume 500mA current, but no more.

If the host is not able to provide the requested current, the enumeration fails. Therefore, the

STMPS2151STR power switch (U24) remains OFF and the MCU part including the extension board is not powered. As a consequence, the green LED LD5 remains turned OFF. In this case, it is mandatory to use an external power supply.

Power supply

Supplying the STM32H7B3I-DK using the external power supply input from VIN (7 to 12 V,

800mA max)

The STM32H7B3I-DK board may require more than 500 mA of supply current. In such a case, the board can be supplied through pin8 (marked VIN on the board) of the CN19 ARDUINO ® connector.

Note that using STLINK-V3E for debugging when powering the board with an external power supply, it is important to power the board before connecting the host PC to CN14, which requires the following sequence to be respected:

Set the jumper between the pins 7-8 of JP1 “ARD”.

Connect the external power source to pin8 of CN19.

Check that the green LED LD5 is turned ON.

Connect the host PC to USB connector CN14.

If this order is not respected, the board may be powered by VBUS first from STLINK, and the following risks may be encountered:

If more than 500 mA current is needed by the board, the PC may be damaged or the current can be limited by the PC. As a consequence, the board is not powered correctly.

500 mA is requested at the enumeration step, so there is a risk that the request is rejected and enumeration does not succeed if the PC cannot provide such current.

Warning:

Board SMPS/LDO firmware PWR configuration must match with the hardware configuration.

If not, you face a deadlock: after the reset, STLINK cannot connect the target anymore.

The firmware PWR configuration corresponds with the following in the main.c:

In the function SystemClock_Config:

• In the case of “Direct SMPS” hardware configuration (default):

•

HAL_PWREx_ConfigSupply(PWR_DIRECT_SMPS_SUPPLY);

In the case of “LDO” hardware configuration:

HAL_PWREx_ConfigSupply(PWR_LDO_SUPPLY);

•

If a deadlock is faced due to a mismatch between the hardware board setting and the firmware setting (LDO/SMPS), the user can recover the board by doing the following:

Power off the board.

Change the SW1 switch position to "1".

This changes the BOOT0 pin to 1 instead of 0 and thus the device boot address is changed to boot address 1 making the bootloader starting in System memory, instead of starting the firmware in the user Flash (Firmware that is setting a wrong LDO/SMPS configuration).

Power on the board, and connect using STM32CubeProgrammer.

Erase the user Flash.

Power off the board and put back the switch SW1 to position "0".

The board is now recovered and can proceed normally.

Measurement of MCU current consumption

The Jumper JP2 allows the current consumption of STM32H7B3LIH6Q to be measured directly by removing the jumper and replace it with an external ammeter. If there is no ammeter, the STM32H7B3LIH6Q is not powered.

Clock source

Three clock sources are available on the STM32H7B3I-DK board:

•

32.768 kHz crystal X1, for the STM32H7B3LIH6Q embedded RTC

24 MHz crystal X4, for the STM32H7B3LIH6Q system clock

25 MHz oscillator X2 for the STLINK-V3E

By default, the 24MHz clock of the camera and USB PHY is provided by the MCO1 clock signal.

Octo-SPI Flash reset

Camera reset

LCD reset

• Wi ‑ Fi ® module reset (optional)

Board functions

TFT color LCD 480x272 pixels

The STM32H7B3I-DK board includes a 4.3-inch LCD touchscreen board which is connected to the RGB interface of the STM32H7B3LIH6Q through the CN1 50-pin connector. The MB1315 LCD board uses the RK043FN48H-

CT672B TFT LCD from Rocktech with a driving system, a white LED backlight, and a capacitive touch panel. The touchscreen controller interfaces with the STM32H7B3LIH6Q via the bidirectional I2C4 bus, since the TFT LCD reset is controlled by the NRST general reset. A U14 external SDRAM is also used to store display data.

USB OTG HS

The STM32H7B3I-DK board supports USB OTG high-speed communication via a CN15 USB Micro-AB connector and a U20 Hi-Speed USB 2.0 external PHY. A U25 USB power switch is also connected to V

BUS

and provides power to CN15. The green LED LD6 is lit in one of these cases:

•

The power switch is ON and the STM32H7B3I-DK board works as a USB host

BUS

is powered by another USB host when the STM32H7B3I-DK board works as a USB device.

The red LED LD8 is lit when an overcurrent occurs (Higher than 500 mA).

The STM32H7B3I-DK board can be powered by the CN15 USB connector at 5 V DC with a 500 mA current limitation.

EXT_I2C

An EXT_I2C connector socket is available on the STM32H7B3I-DK board and offers the possibility to connect external modules via the I2C4 bus. The EXT_RESET is managed by an I/O signal from the STM32H7B3LIH6Q

MCU.

microSD

™

card

A CN4 slot for microSD ™ card (SD 2.0 compliant) is available on the STM32H7B3I-DK board and is connected to the SDIO1 interface of the STM32H7B3LIH6Q. The microSD ™ card detection is managed by the uSD_Detect signal. When a microSD ™ card is inserted in the slot, the uSD_Detect signal level is LOW, otherwise, it is HIGH.

Limitations:

On the STM32H7B3I-DK board, some SDIO1 signals are shared with some digital camera interface DCMI signals. As a consequence, the user must pay attention that there is no camera connected to CN7 when using the microSD ™ card.

Several audio connections are available on the STM32H7B3I-DK board:

An analog microphone input which is connected to ADC of the audio codec through the blue audio jack CN6

An external speaker which can be connected to the audio codec via green audio jack CN5

A CN3 connector offers the possibility to connect a microphone module with up to five ST-MEMS microphones. They are connected to the digital input microphones of STM32H7B3LIH6Q and are managed by the DFSDM interface.

When using the I2S6 interface, make sure that SB46 (I2S6_MCK) and SB31 (I2S6_WS) are ON.

CAN FD

The STM32H7B3I-DK board supports one channel of CAN FD (Flexible Data Rate CAN) compliant bus based on

3V3 CAN transceiver.

The standby signal on the CAN ‑ FD transceiver is controlled by PH8 GPIO of STM32H7B3LIH6Q.

Limitations:

CAN ‑ FD signals are shared with STMod+ signals. As a consequence, the user must take care that nothing is connected to the STMod+ connector (1, 4 pins), or both SB7 and SB12 must be OFF when the FD-CAN1 bus is activated.

CN7 camera module connector

On the STM32H7B3I-DK board, a 30-pin CN7 connector with Digital Camera Interface DCMI signals is available to connect an 8-bit camera module such as the STM32F4DIS-CAM module. This module must be connected with caution before powering the STM32H7B3I-DK board.

The camera clock is the MCO clock by default. I 2 C address for the STM32F4DIS-CAM module is 60h and 61h .

Limitations:

•

Care must be taken of GPIO sharing and multiplexing with other functions, to program the good configuration.

GPIO assignment and sharing are precise below:

• DCMI_SDA and DCMI_SCL I 2 C peripheral are shared with the STMod+ and ARDUINO ® connectors, audio codec, and TFT LCD.

•

Camera signals PA4, PB8, PB9, PC6, PC7, and PD3 are shared with the STMod+ connector.

Camera signals PC9 and PC11 share with SDIO1_D1 and SDIO1_D3 signals

DCMI_HSYNC camera signal (PA4) is shared with the ARDUINO ® ARD_A0 signal.

As a consequence, when using the camera, the user must pay attention that there is nothing connected to

STMod+ connector. And SB44 must be OFF. Same, when using the camera, the microSD ™ cannot be used.

At least, the user must take care that the SB45 is OFF (ARD_A0 signal disconnected to PA4).

1. The 3V3 on ARD connector pin 4 of CN19 is not a power input for the STM32H7B3I-DK board, to simplify power architecture.

2. The external voltage applied to pin VIN on pin 8 of CN19 must be in the range of 6 to 9V at 25°C ambient temperature. If a higher voltage is applied on the regulator U3, it may overheat and could be damaged.

3. Supports analog input only. The current capability is limited to 1 mA when used as digital input or output.

4. By default, pins 5 and 6 of the CN20 connector are connected to ADC MCU input ports PC2_C and PC3_C respectively, thanks to the configuration of solder bridges: SB52 and SB54 closed, SB53 and SB55 opened. In case it is necessary to connect I 2 C interface signals on pins 5 and 6 of CN20 instead of ADC inputs, open SB52 and SB54, close SB53 and SB55.

Before using any ARDUINO ® Uno V3 shield, it is important to refer to

Section 7.2 for a correct configuration of

JPx.

The STM32 MCU I/Os are 3.3 V compatible instead of 5 V for ARDUINO ® Uno V3.

STM32H7B3I-DK board information

Product marking

The stickers located on the top or bottom side of the PCB provide product information:

• Product order code and product identification for the first sticker

• Board reference with revision, and serial number for the second sticker

On the first sticker, the first line provides the product order code, and the second line the product identification.

On the second sticker, the first line has the following format: “MBxxxx-Variant-yzz”, where “MBxxxx” is the board reference, “Variant” (optional) identifies the mounting variant when several exist, "y" is the PCB revision and "zz" is the assembly revision, for example B01. The second line shows the board serial number used for traceability.

Evaluation tools marked as “ES” or “E” are not yet qualified and therefore not ready to be used as reference design or in production. Any consequences deriving from such usage will not be at ST charge. In no event, ST will be liable for any customer usage of these engineering sample tools as reference designs or in production.

“E” or “ES” marking examples of location:

On the targeted STM32 that is soldered on the board (For an illustration of STM32 marking, refer to the

STM32 datasheet “Package information” paragraph at the www.st.com

website).

Next to the evaluation tool ordering part number that is stuck or silk-screen printed on the board.

Some boards feature a specific STM32 device version, which allows the operation of any bundled commercial stack/library available. This STM32 device shows a "U" marking option at the end of the standard part number and is not available for sales.

In order to use the same commercial stack in his application, a developer may need to purchase a part number specific to this stack/library. The price of those part numbers includes the stack/library royalties.
