2.1 Product marking

Evaluation tools marked as “ES” or “E” are not yet qualified and are therefore not ready to be used as reference design or in production. Any consequences arising from such usage will not be at STMicroelectronics’ charge. In no event will STMicroelectronics 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 illustration of STM32 marking, refer to the section Package information in the STM32 datasheet at www.st.com).

• next to the evaluation tool ordering part number, that is stuck or silkscreen printed on the board.

This board features 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.

5.1 STLINK-V3E

STLINK-V3E facility for debug and flashing of STM32G474QET6U is integrated on the STM32G474E-EVAL board. It features:

• Self-powered through a USB connector (Micro-B)

• USB 2.0 high-speed compatible interface

• Direct firmware update support (DFU)

• SWD and serial wire viewer (SWV) communication support

• Drag-and-drop Flash programming

• Two color LEDs: communication, power

The USB connector CN21 can be used to power the STM32G474E-EVAL regardless of the STLINK-V3E facility used for debugging or programming STM32G474QET6U. This holds also when the STLINK stand-alone tool is connected to connector CN14 or CN15 or CN16 or CN17 and used for debugging or programming the STM32G474QET6U.

Power supply provides more detail about powering the STM32G474E-EVAL.

Refer to www.st.com for details about STLINK-V3E.

5.1.1 Drivers and firmware upgrade

The STLINK-V3E requires drivers to be installed on Windows, and embeds a firmware which needs to be updated from time to time in order to benefit from new functionality or corrections. Refer to the Overview of ST-LINK derivatives technical note (TN1235) for details.

Section 5.3:

Before connecting the STM32G474E-EVAL to a Windows (7, 8 10) PC via USB, a driver for STLINK-V3E must be installed. It is available from www.st.com.

5.2 ETM trace

The connector CN17 is available to output trace signals used for debug. By default, the evaluation board is configured such that, STM32G474QET6U signals PE2, PE3 and PE4 are connected to trace outputs TRACECLK, TRACED0, and TRACED1 of CN17, but these signals shared with Audio codec, motor control connectors and FMC.

Tabl e 3 shows the setting of configuration elements to shunt PE3 and PE4 MCU ports to

CN17 connector, to use them as debug trace signals.

Tabl e 4 shows the setting of configuration I/Os to shunt PE2, PE3, PE4 and PE5 MCU ports

to use them as the right functions.

5.3.1 Supplying the board through STLINK-V3E USB port

To power the STM32G474E-EVAL this way, the USB host (a PC) gets connected to the Micro-B USB receptacle of the STM32G474E-EVAL board via a USB cable. The connection event starts the USB enumeration procedure. In its initial phase, the host USB port current supply capability is limited to 100 STM32G474E-EVAL draws power at that time: the U25 STMPS2151 power switch is set to the OFF position, which isolates the rest of the STM32G474E-EVAL from the power source. In the next phase of the enumeration procedure, the host PC informs the STLINK-V3E facility of its capability to supply current up to 300 V3E sets the U25 STMPS2151 switch to ON position to supply power to the rest of the STM32G474E-EVAL board. If the PC USB port is not capable of supplying current up to 300

mA, the CN25 power jack is available to supply the board.

If a short-circuit occurs on the board, the STMPS2151 power switch protects the USB port of the host PC against a current demand exceeding 500 lights up.

The STM32G474E-EVAL board can also be supplied from a USB power source not supporting enumeration, such as a USB charger. In this particular case, jumper JP12 must be fitted with a jumper hat as shown in

bridge settings. STLINK-V3E bypasses STMPS2151 power regardless of enumeration

mA. In such an event, the LD7 LED

Tabl e 5: Power supply related jumper and solder

The LD6 green LED turns on whenever the whole board is powered.

5.3.2 Using STLINK-V3E along with powering through CN25 power jack

When the board requires a current higher than 300 mA, the host PC, connected to STLINKV3E USB port for debugging or programming, cannot supply the STM32G474QET6U MCU. In such a case, the board can be powered through CN25 (marked PSU on the board).

To do this, it is important to power the board before connecting it with the host PC, which requires the following sequence to be respected:

1. Set the jumper JP12 in E5V position

2. Connect the external power source to CN25

3. Check that the green LED LD6 is turned on

4. Connect host PC to USB connector CN21

Caution: In case the board requires more than 300 mA and the host PC is connected via USB before

the board is powered from CN25, the following risk events are possible (listed in reverse severity order):

1. The host PC is capable of supplying 300 mA (the enumeration succeeds) but it features no over-current protection on its USB port. It is damaged due to over- current.

2. The host PC is capable of supplying 300 mA (the enumeration succeeds) and it has a built-in over-current protection on its USB port, limiting or shutting down the power out of its USB port when the excessive current demand from the STM32G474E-EVAL is detected. This causes an operating failure of the STM32G474E-EVAL.

3. The host PC is not capable of supplying 300 mA (the enumeration fails). The STLINKV3E does not supply the rest of the STM32G474E-EVAL from its USB port VBUS line.
