Description

There are two different ways to program and debug the onboard STM32 MCU:
• Using the embedded STLINK-V3E
• Using an external debug tool connected to CN8 STDC14/MIPI-10 connector
The STLINK-V3E facility for debugging and flashing is integrated into the STM32L562E-DK Discovery kit.
The STLINK-V3E makes the STM32L562E-DK Discovery kitArm
The embedded STLINK-V3E supports only SWD and VCP for STM32 devices.
Features supported in STLINK-V3E:
• 5 V power supplied by the CN17 USB connector
• USB 2.0 high-speed-compatible interface
• JTAG and serial wire debugging (SWD) specific features:
– 3 to 3.6 V application voltage on the JTAG/SWD interface and 5V tolerant inputs
– JTAG
– SWD and serial viewer (SWV) communication
• Direct firmware update feature (DFU) (CN6)
• STDC14 (MIPI10) compatible connector (CN8)
• LD3 status LED (COM) which blinks during communication with the PC
• LD11 fault red LED (OC) alerting on USB overcurrent request
• 5 V / 500 mA output power supply capability (U47) with current limitation and LD11 LED
• 5 V power green LD12 LED (5V)

Drivers

Before connecting the STM32L562E-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
In case the STM32L562E-DK board is connected to the PC before the driver is installed, some STM32L562E-DK
interfaces may 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 handle for a full recovery.
