Atmel AT91 ARM Thumb Installation and operating instructions

Using Open Source Tools for AT91SAM7 Cross
Development
1. Introduction
For those on a limited budget, use of open source tools to develop embedded soft-
ware for the Atmel®AT91SAM7 family of ARM®Thumb®based microcontrollers may
be a very attractive approach. Professional software development packages from Keil,
IAR®, Rowley Associates, etc. are convenient, easy to install, well-supported and
fairly efficient. The problem is their price which is a roadblock for the student, hobbyist,
or engineer with limited funding.
Using free open source tools currently available on the web, an acceptable cross
development package can be assembled in an hour’s work. It does require a high-
speed internet connection and a bit of patience.
A complete tutorial is available in the zip file related to this note,
atmel_tutorial_components.zip.
By following the steps outlined in the user guide, you are able to create a development
system that compiles, links and debugs applications for AT91SAM7 microcontrollers.
