Introduction

This document describes the software environment and development recommendations required to build an application around the STM32F429 Discovery (32F429IDISCOVERY).
It provides guidelines to novice users on how to build and run a sample application and to create and build their own application.
This document is structured as follows:

• Chapter 1 describes where to find the ST-LINK/V2 driver that should be installed before starting coding on any Integrated Development Environment
• Chapter 2 describes step by step how to execute and debug an existing project with one of the following toolchains:
  • IAR Embedded Workbench® for ARM (EWARM) by IAR Systems
  • Microcontroller Development Kit for ARM (MDK-ARM) by Keil™
  • TrueSTUDIO® by Atollic
• Chapter 3 describes advanced debugging features
• Chapter 4 provides links to detailed information on the previously mentioned toolchains

Although this manual cannot cover all the topics relevant to software development environments; it demonstrates the first basic steps necessary to get started with the compilers/debuggers and provides links to the documents needed to fully understand every single step.

System requirements

Before running your application, you should:

1. Install your preferred Integrated Development Environment (IDE).
2. Install the ST-LINK V2 driver from the ST web site.
3. Download the STM32F429I-Discovery firmware from the ST web site.
4. Establish the connection with the STM32F429 Discovery board as shown in Figure 1.

To run and develop any firmware applications on your STM32F429 Discovery board, the minimum requirements are as follows:

• Windows PC (2000, XP, Vista, 7)
• USB type A to Mini-B’ cable, to power the board (through USB connector CN1) from the host PC and connect to the embedded ST-LINK/V2 for debugging and programming.

IDEs supporting STM32 family
STMicroelectronics’ STM32 family of 32-bit ARM Cortex-M core-based microcontrollers are supported by a complete range of software tools, encompassing traditional IDEs with C/C++ compilers and debuggers from major 3rd-parties (free versions up to 64KB of code, depending on partner), and completed with innovative tools from STMicroelectronics.

ST-LINK/V2 installation and development
The STM32F429 Discovery board includes an ST-LINK/V2 embedded debug tool interface which requires a dedicated USB driver. This driver is available on the www.st.com ST-LINK V2 page and is supported by these common software toolchains, and others:

• IAR™ Embedded Workbench for ARM (EWARM)
  • The toolchain is installed by default on the PC’s local hard disk in the C:\Program Files\IAR Systems\Embedded Workbench x.x directory.
  • After installing EWARM, install the ST-LINK/V2 driver by running ST-Link_V2_USB.exe from [IAR_install_directory]\embedded Workbench x.x \arm\drivers\ST-Link\ST-Link_V2_USBdriver.exe
• RealView Microcontroller Development Kit (MDK-ARM) toolchain
  • The toolchain is installed by default on the PC’s local hard disk in the C:\Keil directory; the installer creates a start menu shortcut for µVision4.
  • 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” guides you through the steps needed to install the driver from the recommended location.
• Atollic TrueSTUDIO® STM32
  • The toolchain is installed by default on the PC’s local hard disk in the C:\Program Files\Atollic directory.
  • The ST-Link_V2_USB.exe is installed automatically with the software toolchain.

Complementary information on the firmware package and the STM32F429 Discovery requirements are available from the Getting started with STM32 Firmware document.

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

Firmware package
The STM32F429I-Discovery firmware applications, demonstration and IP examples are provided in one package in one zip file. Extracting the zip file generates one folder, STM32F429I-Discovery_FW_VX.Y.Z, which contains the following subfolders:

STM32F429 advanced debugging

The STM32 family using the Cortex-M4 processor has many interrupts and it can be difficult to determine when they are being activated and how often.
Serial Wire Viewer (SWV) on the STM32F429 family makes this task easy. In fact, SWV displays PC Samples, Exceptions (including interrupts), data reads and writes, ITM (printf), CPU counters and a timestamp. This information comes from the ARM CoreSight™ debug module integrated into STM32F429 CPU.
SWV does not steal any CPU cycles and is non-intrusive (except for ITM Debug printf Viewer).
You have already configured Serial Wire Viewer (SWV) on the template project. This allows:

1. Retargeting printf to ITM stimulus port(0). This allows debug messages to display easily. How to use it:
   EWARM : View > terminal IO
   MDK-ARM : View > Serial Windows Debug (printf) Viewer
   TrueSTUDIO: View > SWV Console

2. Exception trace:
   Entry: when the exception enters.
   Exit: When it exits or returns.
   Return: When all the exceptions have returned to the main
   EWARM : ST-LINK > Interrupt log
   MDK-ARM : View > Trace > Exceptions
   TrueSTUDIO: View > SWV Exception Trace Log

3. Function profiler: Shows timing information for the functions in an application
   EWARM : ST-LINK > Function Profiler
   MDK-ARM : View > Analysis Window > Code Coverage
   TrueSTUDIO: View > SWV Statistical Profiling

4. Data Trace Timeline: Shows a graphical representation of the data
   EWARM : ST-LINK > Timeline (Data log)
   MDK-ARM : View > Analysis Window > Logic Analyzer
   TrueSTUDIO: View > SWV Data Trace Timeline
