4.2 Embedded ST-LINK/V2
The ST-LINK/V2 programming and debugging tool is integrated on the
STM32F4DISCOVERY. The embedded ST-LINK/V2 can be used in 2 different ways
according to the jumper states (see Ta b l e 2 ):
● Program/debug the MCU on board,
● Program/debug an MCU in an external application board using a cable connected to
SWD connector CN2.
The embedded ST-LINK/V2 supports only SWD for STM32 devices. For information about
debugging and programming features refer to user manual UM1075 (ST-LINK/V2 in-circuit
debugger/programmer for STM8 and STM32) which describes in detail all the ST-LINK/V2
features.
