STLINK-V3E

STLINK-V3E facility for debugging and flashing of STM32G474QET6 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 LEDs: communication, power
The CN21 USB connector can be used to power the STM32G474E-EVAL regardless of the
STLINK-V3E facility used for debugging or programming STM32G474QET6. This holds
also when the STLINK standalone tool is connected to the CN14, CN15, CN16, or CN17
connector and used for debugging or programming the STM32G474QET6.

Drivers and firmware upgrade

The STLINK-V3E requires drivers to be installed on Windows
needs to be updated from time to time to benefit from new functionality or corrections. Refer
to the technical note Overview of ST-LINK derivatives (TN1235) for details.
Before connecting the STM32G474E-EVAL to a Windows PC via USB, a driver for
STLINK-V3E must be installed. It is available from www.st.com.

ETM trace

The CN17 connector is available to output trace signals used for debugging. By default, the
Evaluation board is configured such that, STM32G474QET6 signals PE2, PE3, and PE4 are
connected to trace outputs TRACECLK, TRACED0, and TRACED1 of CN17, but these
signals are shared with the audio codec, motor control connectors, and FMC.
Table 3 shows the setting of configuration elements to shunt PE3 and PE4 MCU ports to the
CN17 connector, to use them as debug trace signals.
Table 4 shows the setting of configuration I/Os to shunt PE2, PE3, PE4, and PE5 MCU ports
to use them as the right functions.
