Part 3 deals with the linker script. As arcane as it is I am sure that
many readers will find it useful - especially if working on boards or
devices for which Martin has not already provided a script.

BTW I have no connection with the author or the publication in case this
looks like spamming or advertising. Just thought it would be useful to
these wanting to understand the WinARM tools (or other GNU tools for
ARM) or to extend support for other devices.

don't worry. It is very useful.

This thread ought to be made a sticky so it stays at the top of the
subject list.

Part 4 is available:
http://www.embedded.com/rss/showArticle.jhtml?arti...

Deals with compiler options and using C++.

I noticed that "Listing 3" and the subsequent unlabelled listing are in
the wrong order, which might serve to confuse, so watch out for that!

Part 5 now available:
http://www.embedded.com/rss/showArticle.jhtml?arti...

There seems to be a continuing quality control issue with this series,
part 4's section on C++ seems to be repeated almost verbatim here, but
with correctly labelled listings this time!

There is also currently a series on embedded.com titled "The basics of
programming embedded processors" which may be of interest to many. I'll
leave it as an exercise for the reader to find it (there are currently
links on any of the pages posted above). I can recommend using the RSS
feed if you don't want to miss anything.

Your best bet is probably to contact he author. However all the general
principles apply since they are both ARM7 devices. Differences are
primarily in interrupt architectures, memory map, and on board I/O
devices, with some differences in boot processes as well. You'll
probably have to get down-and-dirty with the technical manuals for the
respective parts - but that is what embedded systems programming is
about, it is seldom handed to you done!

However the WinARM suite comes with examples for both NXP and Atmel
parts, you should be able to work from those as a starting point. This
series of articles is really for those that want to work from scratch
and understand in detail what it takes to do board bring-up. If you were
using custom hardware it would be a useful starting point.

While checking out the author's site I did come across the full set of
articles as PDFs and downloadable code, which is probably more acessible
(and printable) than the web series:

The above link no longer works. The whole thing is available as a single
PDF at:
http://www.state-machine.com/arm/Building_bare-met...
with the individual parts and the source code available at
http://www.state-machine.com/resources/papers.htm
