APPLICATION NOTE

STR71xF Embedded Flash Programming with ADS

REV. 1

INTRODUCTION

The purpose of this application note is to provide ARM Developer Suite (ADS) users with information to

help them program binary files to Flash memory using the software’s Flash downloader utility. This document

provides step-by-step instructions for converting an application in ELF format to simple binary format and

then downloading the resulting binary to the internal Flash memory of the STR71xF microcontroller on a

target application board.

Necessary software and hardware tools

●

ARM Developer Suite version 1.2, a complete software development solution for creating

applications for ARM core-based microcontrollers that includes the AXD debugger.

●

Flash downloader (flash.li) for STR71xF, the modified version of the default Flash downloader,

included with this application note, which allows the identification and programming of STR71xF

devices.

Note:

The default integrator version of the Flash downloader that is used to program other standard CFI-

type Flash devices is furnished in binary format in the directory: install_directory\ADS\bin\flash.li.

You may want to keep a copy of the default version of flash.li in another directory or with another

name if you work with devices other than the STR71xF.

●

STR710 Evaluation Board (STR710-EVAL) or other evaluation/application board featuring an

STR71xF microcontroller.

●

ARM MULTI-ICE server and interface unit (JTAG standard interface)

Note:

It is also possible to use ARM Angel Debug Monitor (running from RAM) and a serial or parallel

connection to the host PC. For more information about Angel, refer to the ARM Software

Development Toolkit User Guide.

Overview of Flash programming with ADS

When you invoke the Flash downloader utility (flash.li) from the AXD debugger, the debugger downloads this

utility into RAM on the target board. The microcontroller then executes the Flash programming routine,

retrieving the binary file from the host PC and then programming it to Flash memory.

The Flash downloader utility (flash.li) provided with this application note has been adapted by ST

Microelectronics to allow programming of STR71xF microcontrollers. This modified version must be used

when programming your STR71xF device, instead of the default integrator version of the Flash downloader

that is provided with ADS.
