Now that you have everything setup, the next step is to test it out. The first two are obviously for the Cygwin apps, the last is for the ARM-GCC toolchain. Now make sure your path includes the following: C:\cygwin\bin C:\cygwin\usr\local\bin C:\program files\gnuarm\bin Select “Path” out of the “System Variables”, and click the “Edit” button. Click the “Environment Variables” button. To do this, we must edit the Windows Path variable, which you can access by: Right-click on “My Computer”, click “Properties”. Now that you have the ARM-GCC toolchain installed in a Cygwin environment, you can make these programs globally accessible so you can use them with your own IDE (if you want). This is very important, as installing their version of the Cygwin DLLs apparently will mess things up (according to the ARM Cross Development with Eclipse Tutorial). However, disable the “Install Cygwin DLLs” checkbox. Go through the setup and make sure you have a “Full installiation”.

So, visit the website, go to their files section, scroll down to the Binaries section, and download the latest version of the GCC-4.0 Toolchain for Cygwin.

GNU ARM, a group obviously dedicated to developing GNU tools for ARM architectures, conveniently releases binary distributions of the ARM-GCC toolchain for Cygwin, Linux, and Mac OS X (Linux users: this is probably the only thing you need).
Then finish the installiation (this might take some time depending on your internet connection and the mirror you chose). Specifically, you’ll want to make sure you have the “make” package so you can build source from Makefiles. click on the little circle thing next to each one until they all read “Install”. The general categories recommended by the ARM Cross Development with Eclipse Tutorial are: Archive, Devel, Libs, and Web.

I’m not sure exactly which packages are required for the GNU-ARM toolchain, but you can just install the general categories if disc space isn’t a problem for you. If you ever want to remove or install more packages, simply rerun setup.exe, and if you haven’t deleted those temp files, it will see the already installed cygwin, and take you to removing packages or adding additional ones. It will download these packages off of the internet and install them. In setup.exe, you choose a mirror, the precompiled GNU apps you want and the location of your cygwin directory. You download the installer, which you should keep on your computer. The Cygwin setup is intelligently designed, or so I think. Through Cygwin many GNU apps can be recompiled and ran on Windows, such as GCC and therefore the ARM-GCC toolchain.
The heart of cygwin is the cygwin1.dll, which emulates the Linux API on Windows.

This does not include information on how to setup and operate OCDRemote with GDB- later I might make a short guide on that (once I choose a decent IDE to do my ARM coding in). These are the abridged instructions to install the ARM-GCC toolchain in a GNU environment on Windows, minus the memory killing eclipse. The tutorial is superb, and helped me greatly, but I also decided to post the simplified insturctions in text. Lynch’s “ARM Cross Development with Eclipse Tutorial”. This is a basically a condensed portion (specifically on setting up the basic ARM-GCC toolchain) of James P. Last modified 00:25:11 CDT Setting up the ARM-GCC Toolchain on Windows
