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 two jumpers from CN2 as illustrated in
application to the CN4 debug connector according to
Note: SB12 NRST (target MCU RESET) must be OFF if you use CN4 pin 5 in your external
application.
