6.1 Embedded ST-LINK/V2-1
6.1.1 Description
To debug the on-board STM32 MPU, the ST-LINK/V2-1 programming and debugging tool is integrated in the
STM32MP157x-DKx Discovery kit. The embedded ST-LINK/V2-1 supports only SWD and VCP for STM32
devices. For information about the debugging and programming features of ST-LINK/V2-1, refer to the ST-
LINK/V2 in-circuit debugger/programmer for STM8 and STM32 user manual (UM1075) and Overview of ST-LINK
derivatives technical note (TN1235). It is recommended to power the board (5V_VIN) before plugging the USB
debug cable to the Micro-B connector.
