7.1.1 Description
To debug the onboard STM32 MPU, the ST-LINK/V2.1 programming and debugging tool is integrated in the
STM32MP157A-DK1 and STM32MP157C-DK2 Discovery kits. 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). It is
recommended to power supply the board (5V_VIN) before plugging the USB debug cable to the Micro-B
connector.
