2.2 Embedded ST-LinkThe 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).

Jumper state Description

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

CN3 jumpers OFF ST-Link functions enabled for external application through CN2 connector (SWD supported).

2.2.1 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 STM32F100RBT6B of the STM32 value line Discovery.

Figure 8. Discovery connections image

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.

Figure 9. ST-Link connections image

2.3 Power supply and power selectionThe power supply is provided by a USB connector or external power supply (5 V or 3.3 V). 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).

Note: If the 5V and 3V3 pins are used as an input power supply, the STM32VLDISCOVERY board must be powered by a power supply unit or auxiliary equipment complying with standard EN-60950-1: 2006+A11/2009, and must be safety extra low voltage (SELV) with limited power capability.

2.4 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 STM32F100RBT6B.

● LD4: Blue LED LD4 labeled PC8 is connected to the I/O PC8 of STM32F100RBT6B.

2.5 Push buttons● B1: Push button B1 labeled USER is connected to the I/O PA0 of STM32F100RBT6B

and can be used as WAKE-UP.

● B2: Push button B2 labeled RST is dedicated to the RESET pin of STM32F100RBT6B.

2.6 JP1 (Idd)Jumper JP1, labeled Idd, allows the consumption of STM32F100RBT6B to be measured by removing the jumper and connecting an ammeter.

● Jumper on: STM32F100RBT6B is powered (default).

● Jumper off: STM32F100RBT6B is not powered.
