6.1.5 Using
ST-LINK/V2-1
to program/debug an external
STM32 application
It is very easy to use ST-LINK/V2-1 to program an STM32 microcontroller on an external
application. Simply remove the two jumpers from CN4 as shown in
and connect the
application to the CN5 debug connector according to
Note:
SB13, must be OFF if CN5 pin 5 (NRST) is used in the external application.
