6.3 Embedded STLINK-V3E
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 CN16 MIPI10 connector.
The STLINK-V3E programming and debugging tool is integrated into the STM32WL Nucleo-64 board.
The embedded STLINK-V3E supports only SWD and VCP for STM32 devices. For information about debugging
and programming features of STLINK-V3, refer to the user manual STLINK-V3SET debugger/programmer for
STM8 and STM32 (UM2448), which describes in detail all the STLINK-V3 features.
Features supported on STLINK-V3E:
5V power supplied by CN1 USB connector
USB 2.0 high-speed-compatible interface
SWD JTAG/serial wire debugging specific features:
3 V to 3.6 V application voltage on the JTAG/SWD interface and 5 V tolerant inputs
JTAG
Serial viewer communication
