6.2.3 Using the ST-LINK/V2-1 to program and debug the STM32 on board
To program the STM32 on the board, plug in the two jumpers on CN2, as shown in red in
Figure 8. Do not use the CN4 connector as this could disturb the communication with the
STM32 microcontroller of the STM32 Nucleo board.

6.2.4 Using ST-LINK/V2-1 to program and 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 illustrated in
Figure 9: Using ST-LINK/V2-1 to
program the STM32 on an external application, and connect the application to the CN4
debug connector according to Table 5.
Note: SB12 NRST (target STM32 RESET) must be OFF if CN4 pin 5 is used in the external
application.
