Description
There are two different ways to program and debug the onboard STM32 MCU:
1.
Using the embedded STLINK-V3E programming and debugging tool which is on the STM32U575I-EV
Evaluation board
2.
Using an external debug tool connected to the CN18 STDC14/MIPI-10 connector
The STLINK-V3E makes the STM32U575I-EV Evaluation board Arm
®
Mbed Enabled
™
.
The embedded STLINK-V3E only supports SWD and VCP for STM32 devices:
•
5 V power supplied by the CN26 USB connector
•
USB 2.0 high-speed-compatible interface
•
JTAG and SWD protocols compatible with 1.7 to 3.6 V application voltage and 5 V tolerant input I/Os
•
Serial Wire Viewer (SWV) output
•
STDC14/MIPI-10 compatible connector (CN18)
•
Status COM LED which blinks during communication with the PC (LD4)
•
Fault red OC LED alerting on USB overcurrent request (LD3)
•
5 V / 500 mA output power supply capability with current limitation (U20)
•
5 V power green LED (LD2)

Drivers
Before connecting the STM32U575I-EV Evaluation 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
website.
In case the STM32U575I-EV Evaluation board is connected to the PC before the driver is installed, some
STM32U575I-EV Evaluation board interfaces may be declared as
Unknown
in the PC device manager. In this
case, the user must install or update the driver files, and update the driver of the connected device from the
device manager as shown in
.
Note:
Prefer using the USB Composite Device handle for a full recovery.
