Atmel AT91 ARM Application Note

Using Open Source Tools for AT91SAM7 Cross
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
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.
