In my AT32UC3A1512 application, I need to make some small changes to the behaviour of the ISP USB DFU bootloader. I just need to set a couple of I/O pins before proceeding with the test for whether or not to execute the application code.

The source code and Makefile for the bootloader are supplied in

C:\Program Files\Atmel\1.3.0-AT32UC3A\SERVICES\USB\CLASS\DFU\EXAMPLES\ISP\AT32UC3A\GCC

However, on my Win XP system I can't just run "make rebuild" to rebuild the code.

Is there some simple way for a non-Linux expert to rebuild the boot loader code on a Windows system?

Thanks in advance for any advice you can offer.

Regards,

Bert Menkveld

Try to install Cygwin (http://www.cygwin.com/) and use their shell.

Thanks for the suggestion. I'm a bit nervous about doing this, since a colleague ran into a lot of trouble with apparent conflicts between AVR32 Studio and his cygwin installation.

Do others use cygwin alongside AVR32 Studio? Any particular installation tips that I should be aware of?

I do not use the AVR32 studio to build to code.
I use the command line in Win XP and it works smoothly.

Although, I have cygwin installed, but I do not use the cygwin prompt to do anything.
If you want to try installing cygwin, it should be pretty straight forward. I did not face any problems with it.

If you could post the errors you are getting, I might be able to help you.

I took the suggestion and installed cygwin. There were no problems with installing it, AVR32 Studio still works fine, and I can now happily rebuild the bootloader.

Thanks for the help.
