I have made a setup in Eclipse to work with the Arduino libraries. This works perfectly fine for a Arduino Duemilanova; but not for the Mega. The Mega however does play nice with the Arduino 17 software.
My setup consists of the ‘blinking led’ example code. When this works on the Duemilanova, I change the target processor, compile again and upload to the chip using a AVR ISP MkII. It then doesn’t work: no blinking led.
Are there any different compile flags, library settings, etc. for Duemilanova/Mega I have to know off? Other things to try?
