Embedded ST-Link
The ST-Link programming and debugging tool is integrated on the STM32 value line
Discovery. The embedded ST-Link can be used in 2 different ways:
●
to program/debug the MCU on board
●
to program/debug an MCU in another application board using a cable connected to
SWD connector CN2.
For information about debugging and programming features refer to ST-Link UM0627.
Note:
UM0627 contains information about all the ST-Link features. Usage in this situation is
restricted to STM32F devices and SWD support only (no JTAG).
Figure 7.
Typical configuration
Hardware requirements:
- USB cable type A to mini-B
- Computer with Windows 2000, XP or Vista OS
Development toolchain:
- Atollic, TrueSTUDIO®
- IAR, Embedded Workbench® for ARM
- Keil, MDK-ARMTM

Description
CN3 jumpers ON
ST-Link functions enabled for on board programming (default)
CN3 jumpers OFF

2.2.1
UM0919
Using the ST-Link to program/debug the STM32 on board
To program the STM32 on board, simply plug in the two jumpers on CN3, but do not use the
CN2 connector as that could disturb communication with the STM32F100RB of the STM32
value line Discovery.
Figure 8.

Jumpers on CN3
2.2.2
Using the ST-Link to program/debug an external STM32 application
It is very easy to use the ST-Link to program the STM32 on an external application. You
simply remove the 2 jumpers from CN3 and connect your application to the CN2 debug
connector (as shown in Figure 9 and according to Table 2.).
Note:
Only SWD is supported, not JTAG.

Power supply and power selection
The power supply is provided by a USB connector or external power supply (5 V or 3.3V ).
The 5V (P2 pin 26) and 3V3 (P1 pin 3) pins can be used independently as input or output
power supplies due to D1 and D2 protection diodes (see Figure 3).

LEDs
●
LD1: Red LED LD1 labeled COM indicates communication between PC and ST-Link.
●
LD2: Red LED LD2 labeled PWR indicates that the board is powered.
●
LD3: Green LED LD3 labeled PC9 is connected to the I/O PC9 of STM32F100RB.
●
LD4: Blue LED LD4 labeled PC8 is connected to the I/O PC8 of STM32F100RB.

●
B1: Push button B1 labeled USER is connected to the I/O PA0 of STM32F100RB and
can be used as WAKE-UP.
●
B2: Push button B2 labeled RST is dedicated to the RESET pin of STM32F100RB.
