6.4.4 Using 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 2 jumpers from CN4 as shown in
Figure 8, and connect your application
to the CN11 debug connector according to Table 6.
Note: SB19 must be OFF if you use CN11 pin 5 in your external application.
