Hardware and layout

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-ARM

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 STM32F100RBT6B 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. Table 2.

Power supply and power selection The 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.
