Using ST-LINK/V2 (or V2-B) to program/debug an external STM32

application

It is very easy to use the ST-LINK/V2 (or V2-B) to program the STM32 on an external
application. Remove the two jumpers from CN4 as shown in
connections, and connect the application to the debug connector (CN3) according to
Table 5.
Note: SB7 must be OFF if the CN3 pin 5 is used in an external application.
