5.1.2 Using ST-LINK/V2 to program/debug an external STM32 application
It is very easy to use the ST-LINK/V2 to program the STM32 on an external application.
Simply remove the 2 jumpers from CN5 as shown in Figure 6, and connect the application
to the CN4 debug connector according to Table 5.
Note: SB10 must be OFF if CN4 pin 5 is used by the external application.
