I've only just got my new ibook set up with Tiger and the avr-tool chain, but haven't had a chance to get test it on xcode 2 and tiger. I used replaced the /usr/bin/gdb with a symbolic link to avr-gdb as follows cp /usr/bin/gdb /usr/bin/ppc-gdb

#to setup
rm /usr/bin/gdb
 ln -s /usr/local/bin/avr-gdb /usr/bin/gdb

#to restore.
rm /usr/bin/gdb
ln -s /usr/bin/ppc-gdb /usr/bin/gdb

You could easily put this into a script to help streamline the proccess. Ihaven't had a chance yet to fool around in xcode 2.0 so there might be an easier way of doing this.

The main problem I had with avarice was that there is no 'run' command as with a normal gdb session. The avarice only accepts 'cont' to start the debugging session. I'm sure I can get around this behaviour with a bit more tweaking but as I say I haven't had enough time lately. So I could get xcode to start the degugger, connect to the remote target (avarice) but could not get any useful advantage out of it (ie. still only using the console)

Have you seen the article here.

Do you know of any MacOS X embedded resources? Here are some of the links that have helped me (with AVR)

I also hope to get this going with the gnu-arm tool chain as well. If you have any ideas or suggestions please don't hesitate to send me an email.

Nick: Did you ever figure out how to get Xcode's debugger to use AVR-GDB instead of the normal version for the PPC?
Thanks,
