Using the ST-LINK/V2-1 to program/debug the STM32

To program the STM32, place the two jumpers marked in red on the connector CN2, as
shown in
STM32 microcontroller of the Nucleo-64-P board.
ST-LINK jumper ON:
CN2 [1-2] and [3-4]
SWD connector: CN3

Using the ST-LINK/V2-1 to program/debug an external STM32

application.

It is very easy to use the ST-LINK/V2-1 to program the STM32 on an external application.
Simply remove the two jumpers from CN2, as shown in
application to the SWD debug connector according to
Note: JP4 NRST (target STM32 RESET) must be opened when CN3 pin 5 is used in an external
application.
