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 the STDC14/MIPI10 connector (CN8)
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 USB connector (CN17)
• USB 2.0 high-speed-compatible interface
• JTAG and Serial Wire Debug (SWD) specific features:
– 3 to 3.6 V application voltage on the JTAG/SWD interface and 5 V tolerant inputs
– JTAG
– SWD and Serial Wire Viewer (SWV) communication
• STDC14 (MIPI10) compatible connector (CN8)
• COM status LED (LD3) which blinks during communication with the PC
• OC fault red LED (LD11) alerting on USB overcurrent request
• 5 V/500 mA output power supply capability (U47) with current limitation and LED (LD11)
• 5 V power green LED (LD12)

Drivers

Before connecting the STM32L562E-DK board to a Windows PC via USB, the user must install a driver for
STLINK-V3E (not required since Windows
In case the STM32L562E-DK board is connected to the PC before the driver is installed, some STM32L562E-DK
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 handle for a full recovery.
