6.3.3.2 Using the ST-LINK/V2-1 to program and debug an external STM32 application
It is easy to use the ST-LINK/V2-1 to program the STM32 on an external application.
Simply remove the two jumpers from CN4, as shown in
Figure 9 , and connect your application to the SWD debug
connector (CN5) according to Table 6 .
Note: JP3 T_NRST (target STM32 reset) must be open when CN5 pin 5 is used with an external application.
