5.1 Embedded ST-LINK/V2
The ST-LINK/V2 programming and debugging tool is integrated on the STM32F072
Discovery kit. The embedded ST-LINK/V2 can be used in 2 different ways according to the
jumper states (see
Table 4 ):
•
Program/debug the MCU on board
•
Program/debug an MCU in an external application board using a cable connected to
SWD connector CN4
The embedded ST-LINK/V2 supports only SWD for STM32 devices. For information about
debugging and programming features, refer to user manual UM1075 (ST-LINK/V2 in-circuit
debugger/programmer for STM8 and STM32), which describes in detail all the ST-LINK/V2
features.
5.1.1 Using ST-LINK/V2 to program/debug the STM32F072 on board
To program the STM32F072 on board, simply plug in the two jumpers on CN5, as shown in
Figure 5 in pink, but do not use the CN4 connector as that could disturb communication with
the STM32F072RBT6 of the STM32F072 Discovery kit.
