The Due toolchain

Does anyone have a clue what the Arduino Team is using as a toolchain for Due. In the past the answer has been "it is in alpha so don't ask".

What are the truly free open options for ARM development on Windows?

I was using YAGARTO for ARM but when I went to the website I found:

Task completed

This domain was registered in July 2006 and started with the motivation to create a toolchain with the following features:

not based on Cygwin working with Eclipse cheap for beginners

This sounds like YAGARTO is no longer supported.

I have also used the Sourcery CodeBench Lite Edition from Mentor Graphics.

Are there other options?

I would use Linux but STMicroelectronics releases most of its tools for Windows and I mostly develop for STM32.

I have found the Code Sourcery tools to be the best. They have a nice set of startup code, and they produce the leanest code (sometimes factor 2). Leaf Labs distributes a version of CS they built themselves, too. There is also devkitARM, which works fine. Yagarto still works, he just isn't going to produce any more revs. You could conceivably just maintain the Yagarto patches, and make changes as needed to accomodate future revs of the individual tools.

I also found this article, http://balau82.wordpress.com/2010/12/05/using-ubuntu-arm-cross-compiler-for-bare-metal-programming/ which talks about using the Ubuntu gcc-arm-linux-gnueabi toolchain and avoiding Linux.

Thanks, I have had good luck with Code Sourcery and guess I should be comfortable with Mentor Graphics continuing to provide the free lite version.

Most of the large physics experiments I have been involved with use Mentor Graphics tools for advanced circuit and semiconductor design, simulation, verification, and emulation. Mentor Graphics has good relationships with labs and universities.

Guess I should be thankful for how well Code Sourcery works.
