2 Getting started

2.1 System requirements

Before running your application, you should establish the connection with the

STM32F4DISCOVERY board as following.

Figure 1. Hardware environment

To run and develop any firmware applications on your STM32F4DISCOVERY board, the

minimum requirements are as follows:

– Windows PC (2000, XP, Vista, 7)

– 'USB type A to Mini-B' cable, used to power the board (through USB connector

CN1) from host PC and connect to the embedded ST-LINK/V2 for debugging and

programming

Additional hardware accessories will be needed to run some applications:

– 'USB type A to Micro-B' cable, used to connect the board (through USB connector

CN5) as USB Device to host PC.

– Headphone with male jack connector.

Getting started UM1467

5/46 Doc ID 022172 Rev 1

2.2 Running the built-in demonstration

The board comes with the demonstration firmware preloaded in the Flash memory. Follow

the steps below to run it:

– Check jumper position on the board, JP1 on, CN3 on (Discovery selected).

– Connect the STM32F4DISCOVERY board to a PC with a 'USB type A to Mini-B'

cable through USB connector CN1 to power the board. Red LED LD2 (PWR) then

lights up.

– Four LEDs between B1 and B2 are blinking.

– Press User Button B1 then MEMS sensor is enabled, move the board and observe

the four LEDs blinking according to the motion direction and speed.

– If you connect a second 'USB type A to Micro-B' cable between PC and CN5

connector then the board is recognized as standard mouse and its motion will also

control the PC cursor.

functions for use on Cortex-M processor based devices. The library is completely

written in C and is fully CMSIS compliant. High performance is achieved through

maximum use of Cortex-M4F intrinsics.

STM32F4xx CMSIS files consist of:

–stm32f4xx.h: this file contains the definitions of all peripheral registers, bits, and

memory mapping for STM32F4xx devices. The file is the unique include file used in

the application programmer C source code, usually in the main.c.

4 Binary images for reprogramming firmware

applications

This section describes how to use the provided binary images to reprogram the firmware

applications. The STM32F4DISCOVERY firmware package contains binary images (*.hex

and *.dfu) of the provided applications which allow to use the STM32F4xx's embedded

Bootloader or any in-system programming tool to reprogram these applications easily.

Below are the steps to follow:

●Using “in-system programming tool”

– Connect the STM32F4DISCOVERY board to a PC with a 'USB type A to Mini-B'

cable through USB connector CN1 to power the board.

– Make sure that the embedded ST-LINK/V2 is configured for in-system

programming (both CN3 jumpers ON).

– Use *.hex binary (for example,

\Project\Demonstration\Binary\STM32F4-Discovery_Demonstration_V1.0.0.hex)

with your preferred in-system programming tool to reprogram the demonstration

firmware (ex. STM32 ST-LINK Utility, available for download from www.st.com).

●Using “Bootloader (USB FS Device in DFU mode)”

– Configure the STM32F4DISCOVERY board to boot from “System Memory” (boot

pins BOOT0:1 / BOOT1:0)

– Set BOOT0 pin to high level: on the male header P2 place a jumper between

BOOT0 pin and VDD pin

– Set BOOT1(PB2) pin to low level: on the male header P1 place a jumper between

PB2 pin and GND pin

– Connect a 'USB type A to Mini-B' cable between PC and USB connector CN1 to

power the board.

– Connect a 'USB type A to Micro-B' cable between PC and USB connector CN5,

the board will be detected as USB device.

– Use *.dfu binary (for example,

\Project\Demonstration\Binary\STM32F4-Discovery_Demonstration_V1.0.0.dfu)

with “DFUse\DFUse Demonstration" tool (available for download from

www.st.com) to reprogram the demonstration firmware.

UM1467 ST-LINK/V2 installation and development

Doc ID 022172 Rev 1 10/46

5 ST-LINK/V2 installation and development

STM32F4DISCOVERY board includes an ST-LINK/V2 embedded debug tool interface that

is supported by the following software toolchains:

●IAR™ Embedded Workbench for ARM (EWARM) available from www.iar.com

The toolchain is installed by default in the C:\Program Files\IAR Systems\Embedded

Workbench 6.2 directory on the PC’s local hard disk.

After installing EWARM, install the ST-LINK/V2 driver by running the

ST-Link_V2_USB.exe from [IAR_INSTALL_DIRECTORY]\Embedded Workbench

6.2\arm\drivers\ST-Link \ST-Link_V2_USBdriver.exe

●RealView Microcontroller Development Kit (MDK-ARM) toolchain available from

www.keil.com

The toolchain is installed by default in the C:\Keil directory on the PC’s local hard disk;

the installer creates a start menu µVision4 shortcut.

When connecting the ST-LINK/V2 tool, the PC detects new hardware and asks to install

the ST-LINK_V2_USB driver. The “Found New Hardware wizard” appears and guides

you through the steps needed to install the driver from the recommended location.

●Atollic TrueSTUDIO® STM32 available from www.atollic.com

The toolchain is installed by default in the C:\Program Files\Atollic directory on the PC’s

local hard disk.

The ST-Link_V2_USB.exe is installed automatically when installing the software

toolchain.

●Altium™ TASKING VX-toolset for ARM® Cortex-M available from www.tasking.com

The toolchain is installed by default in the “C:\Program Files\TASKING directory on the

PC’s local hard disk. The ST-Link_V2_USB.exe is installed automatically when

installing the software toolchain.

Note: The embedded ST-LINK/V2 supports only SWD interface for STM32 devices.

Refer to the firmware package release notes for the version of the supporting development

toolchains.
