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
.

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
case, do not use the CN5 SWD connector as that can disturb communication with the STM32 microcontroller of
the Nucleo.
