Drivers
Before connecting the B-G473E-ZEST1S Discovery board to a Windows PC via USB, the user must install a driver for the STLINK-V3EC (not required for Windows 10). It is available on the www.st.com website.
In case the B-G473E-ZEST1S Discovery board is connected to the PC before the driver is installed, some B-G473E-ZEST1S Discovery board interfaces might 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 Figure 5.

Note:
Prefer using the USB Composite Device to handle a full recovery.

Firmware upgrade
STLINK-V3EC embeds a firmware upgrade mechanism for in‑place upgrades through the USB port. As the firmware might evolve during the lifetime of the STLINK- V3EC product (for example new functionalities, bug fixes, and support for new microcontroller families), it is recommended to visit the www.st.com website before starting to use the B-G473E- ZEST1S Discovery board and periodically, to stay up-to-date with the latest firmware version.

Use of an external debugging tool to program and debug the on-board STM32
There are two basic ways to support an external debugging tool:

1. Keep the embedded STLINK-V3EC running. Power on the STLINK-V3EC at first until the COM LED lights are red. Then connect the external debugging tool through the STDC14/MIPI10 debug connector (CN2).
2. Connect the USART connector on the external debugging tool (for example, STLINK-V3SET) to the USART connector (CN1) for the second VCP (optional).

I/O restriction to other features

Caution:
Due to the sharing of some I/Os of STM32G473QET6 by multiple peripherals, the following limitations apply in using the STDC14 and USART2 features:

• By default, VCP1_TX is connected to PG9 without bootloader support. VCP1_TX can be connected to PA9 with the bootloader by setting SB51 and SB60 OFF and SB54 ON (removing SB60 disconnects Morpho MC (CN7) pin35). If PA9 is used as VCP1_TX, Morpho MC (CN7) pin35 cannot be used.
• By default, VCP2_RX is not connected. VCP2_RX can be connected to PD6 by setting SB49 ON (sharing with LED2).

Power supply

5 V power supply general view
The B-G473E-ZEST1S Discovery board is designed to be powered from the 5 V DC power source. One of the following five 5 V DC power inputs can be used, upon an appropriate board configuration:

• P5V from CN5 MC connector V2 (CN5) for power board (default)
• 5V_USB_STLK from the USB Type-C® receptacle (CN4) of STLINK-V3EC
• E5V from Morpho MC connector (CN7) for custom daughterboard
• 5V_USB_CHGR from the USB Type-C® receptacle (CN4) of STLINK-V3EC, in the case of a wall charger (no enumeration)

The green LED (LD4) turns on when the voltage on the power line marked as 5V is present. All supply lines required for the operation of the components on B -G473E-ZEST1S are derived from that 5V line. Table 10 describes the 5V power supply capabilities.

P5V power source
P5V is the DC power coming from the power board through MC connector V2 (CN5). In this case, the JP2 jumper must be on pin [1-2] to select the P5V power source on the JP2 silkscreen. This is the default setting.

5V STLINK-V3EC source: 5V_USB_STLK
5V_STLK is a DC power with limitations from the STLINK-V3EC USB Type-C® connector. In this case, the JP2 jumper must be on pin [3-4] to select the STLK power source on the JP2 silkscreen. If the USB enumeration succeeds, the 5V_STLK power is enabled, by asserting the T_PWR_EN signal, coming from the STLINK-V3EC MCU (U12). This pin is connected to a USB power switch (U15), which powers the board. This power switch features also a 500 mA current limitation, to protect the PC in case of an on-board short-circuit. The B -G473E-ZEST1S board, with its shield on it, can be powered from the STLINK- V3EC USB connector (CN4), but only the STLINK-V3EC circuit has the power before USB enumeration, as the host PC only provides 100 mA to the board at that time. During the USB enumeration, the B-G473E-ZEST1S board asks for 500 mA power to the host PC.

If the host can provide the required power, the enumeration finishes with a SetConfiguration command, and then, the power switch is switched ON, the 5V green LED (LD4) turns ON, thus the B-G473E-ZEST1S board and its shield on it can consume 500 mA current, but no more. If the host is not able to provide the requested current, the enumeration fails. Therefore, the power switch remains OFF and the MCU power domain, including the extension board, is not powered. As a consequence, the 5V green LED (LD4) remains turned OFF. In this case, it is mandatory to use an external power supply.

E5V power source
E5V is the DC power coming from the Morpho MC connector (CN7). In this case, the JP2 jumper must be set on pin [5-6] to select the E5V power source on the JP2 silkscreen.

5V_CHG power source
VBUS_STLK is the DC power charger connected to STLINK-V3EC USB (CN4). To select the CHG power source on the JP2 silkscreen, the jumper of JP2 must be set on pins [7-8]. If the B-G473E-ZEST1S board is powered by an external USB charger, then the debug is not available. If a computer is connected instead of the charger, the current limitation is no longer effective. Never use this configuration with a computer connected instead of the charger, because the USB_PWR_protection is bypassed, and if the board consumption is more than 500 mA, this can damage the computer. To avoid this risk, it is recommended to select 5V_STLK mode.

Programming/debugging when the power supply is not from STLINK-V3EC (5V_STLK)
P5V or E5V can be used as an external power supply in case the current consumption of the B-G473E-ZEST1S with expansion boards exceeds the allowed current on USB. In such a condition, it is still possible to use USB for communication for programming or debugging only. In this case, it is mandatory to power the board first using P5V or E5V then connect the B-G473E-ZEST1S USB cable to the PC. Proceeding this way, the enumeration succeeds thanks to the external power source.

The following power sequence procedure must be respected:

1. Connect the JP2 jumper according to the external 5V power source selected.
2. Connect the external power source selected.
3. Power on the external power supply source.
4. Check that the 5V green LED (LD4) is turned ON.
5. Connect the PC to the B-G473E-ZEST1S USB connector (CN4).

If this sequence is not respected, VBUS from STLINK-V3EC might power the board first, and the following risks might be encountered:

• If the board needs more than 500 mA, it might damage the PC or the PC limits the current. Therefore, the board is not powered correctly.
• A 500 mA current is requested at enumeration. If the PC does not provide such a current, the request might be rejected, and enumeration does not succeed. Consequently, the board is not powered, and the green LED (LD4) remains OFF.

Clock sources
Two clock references are available on B-G473E-ZEST1S for the STM32G473QET6 target microcontroller.

• 32.768 kHz crystal X2 for embedded RTC (LSE)
• 24 MHz oscillator X1 for HSE clock

Reset sources
The reset signal of the STM32G473QET6 on the B-G473E-ZEST1S Discovery board is active LOW. Sources of reset are:

• B1 reset button (black button)
• CN2 STDC14 connector (CN2), reset from debug tools
• Embedded STLINK-V3EC MCU (U12)

RSS/bootloader

Description
The bootloader is located in the system memory, programmed by ST during production. It is used to reprogram the flash memory via USART, I2C, SPI, CAN FD, or USB FS in device mode through the DFU (device firmware upgrade). The bootloader is available on all devices. Refer to the application note STM32 microcontroller system memory boot mode (AN2606) for more details.

The Root Secure Services (RSS) are embedded in a flash memory area named the secure information block, programmed during ST production. For example, it enables Secure Firmware Installation (SFI), thanks to the RSS extension firmware (RSSe SFI). This feature allows customers to protect the confidentiality of the firmware to be provisioned into the STM32 when production is subcontracted to an untrusted third party. The Root Secure Services are available on all devices, after enabling the TrustZone® through the TZEN option bit. The bootloader version can be identified by reading the bootloader ID at the address 0x0BF99EFE.

Boot from RSS
The BOOT0 value might come from the PB8_BOOT0 pin, connected to the BOOT jumper JP1, or from an option bit depending on the value of a user option bit. Table 11 describes the hardware configuration of the switch SW1 for the Boot mode.

Table 11. BOOT selection switch

1. The default configuration is in bold.

Caution:
PB8_BOOT0 is also used as a Hall sensor signal of Motor2, the pull-up resistor on the Hall sensor signal (M2_Hall_3) might impact the function of BOOT0, thus MCU does not boot from flash memory. When using M2_Hall_3, the BOOT0 feature must be bypassed by setting the nSWBOOT0 option byte to LOW, and nBOOT0 and mBOOT1 bytes to HIGH.

MC connector V2

Description

• MC connector V2 is a new generation interface between the control board and the power board (or adaptor board). It is a PCI Express format connector. On B-G473E-ZEST1S, this connector is a PCI-E 16x edge-finger.
• Three motors, PFC, SPI, and ADCs signals are implemented on MC connector V2. The signals of the second motor (Motor 2) signals are shared with the Morpho MC signals.

B-G473E-ZEST1S product information

Product marking
The stickers located on the top or bottom side of all PCBs provide product information:

• First sticker: product order code and product identification, generally placed on the main board featuring the target device.
  Example:

• Second sticker: board reference with revision and serial number, available on each PCB.
  Example:
  

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.

Parts marked as “ES” or “E” are not yet qualified and therefore not approved for use in production. ST is not responsible for any consequences resulting from such use. In no event will ST be liable for the customer using any of these engineering samples in production. ST’s Quality department must be contacted before any decision to use these engineering samples to run a qualification activity.

“ES” or “E” 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 sale. To use the same commercial stack in their applications, the developers might need to purchase a part number specific to this stack/library. The price of those part numbers includes the stack/library royalties.
