Hello,
so you've got one step further. That's good.
My interrupt routine looks the same. I'm not sure what is wrong. I had a similar problem when I migrated my Project from an CCS 3.3 Version to CCS 5. Then I created a completly new project in CCS 5 (no migration!) and it worked. I don't know why. Maybe the .tcf-file was corrupted in my migrated project. I hope that helps.
