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 Table 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.
