upgrading from NIOS II EDS 7.2 to 9.1

I had a NIOSII C project which compiled and debugged/ran on my custom board under 7.2. Installed 9.1 and pointed to the workspace. could not get anywhere with it. The IDE seemed to think I was trying to run a local app (on windows?).....

anyway, I punted and created a new workspace and new "helloworld" project based on the bsp, and stepped thru it successfully. then I started dropping my source code in the directory and worked thru some other issues, but I am now able to run and step thru my program.

Couple notes to Altera about this little exercise:

1. It is trendy to bash Microsoft, but when going from VS2005 to VS2008, it automatically converts your project to the new version -- AND IT WORKS!!! Altera should take note.

2. It would be *really* nice for the Nios II Software Developer's Handbook to tell me which include file the functions are defined in. For example, the handbook was kind enough to tell me that the function alt_irq_interruptible is deprecated. It is not defined where it used to be. It is now in priv/alt_legacy_irq.h. Not inherently obvious to me.

3. I am running Vista 32 Home Premium. It is *very* important that you run the NIOS@EDS as ADMINISTRATOR when creating a new project. All those scripts just dont run and the error messages are too cryptic to be helpful. A heads-up about that would be nice.

This kind of grief is why it took me so long to upgrade from 7.2. I have been writing code for the NIOS since before the environment moved to Eclipse and each upgrade was so unnecessarily painful.

The sad thing is that there is probably a lot easier/faster way to convert my project, but I did not find it....

thanks
