The ST-LINK/V2-1 programming and debugging tool is integrated in the STM32 Nucleo 
boards.

The ST-LINK/V2-1 makes the STM32 Nucleo boards mbed enabled.

The embedded ST-LINK/V2-1 supports only SWD for STM32 devices. For information about 
debugging and programming features refer to 

, which describes in detail all the 

ST-LINK/V2 features.

The changes versus ST-LINK/V2 version are listed below.
•

New features supported on ST-LINK/V2-1:
–

USB software re-enumeration

–

Virtual com port interface on USB

–

Mass storage interface on USB

–

USB power management request for more than 100 mA power on USB

•

Features not supported on ST-LINK/V2-1:
–

SWIM  interface 

–

Minimum supported application voltage limited to 3 V

There are two different ways to use the embedded ST-LINK/V2-1 depending on the jumper 
states (see 

 and 

•

Program/debug the MCU on board (

•

Program/debug an MCU in an external application board using a cable connected to 
SWD connector CN4 (

          

Both CN2 jumpers ON 

ST-LINK/V2-1 functions enabled for on board programming 

(default) 

Both CN2 jumpers OFF 

ST-LINK/V2-1 functions enabled for external CN4 connector
