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. http://www.embedded.com/rss/showArticle.jhtml?articleID=201000339&cid=RSSfeed_embedded_news 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. Clifford

This thread ought to be made a sticky so it stays at the top of the subject list. Andy
Part 4 is available: http://www.embedded.com/rss/showArticle.jhtml?articleID=201001729&cid=RSSfeed_embedded_news 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! Clifford
Part 5 now available: http://www.embedded.com/rss/showArticle.jhtml?articleID=201200388 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. Clifford
Is there a port of this examples available for lpc2000? mgiaco

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: http://www.quantum-leaps.com/resources/papers.htm##GNU-ARM Clifford

The whole thing is available as a single PDF at: http://www.state-machine.com/arm/Building_bare-metal_ARM_with_GNU.pdf with the individual parts and the source code available at http://www.state-machine.com/resources/papers.htm
