NUCLEO ST-LINK/V2-1 hardware configuration
The embedded ST-LINK/V2-1 can be used in two different ways according to the jumper states, refer to
for setting, depending on the configuration:
•
Program/debug the MCU on-board
•
Program/debug an MCU in an external application board using a cable connected to SWD connector
.

6.3.3.1
Using the ST-LINK/V2-1 to program and debug the STM32 on-board
To program the STM32 on-board, plug in the two jumpers on the CN4 connector, as shown in
. In this
case, do not use the CN5 SWD connector as that can disturb communication with the STM32 microcontroller of
the Nucleo.
