ATmega1284P: End to End using 1.0 IDE

westfw:
Try connecting CTS and DSR to DTR ("before" the cap that goes to the arduino reset pin.)

I can't quite tell whether your sparkfun board (the one in your picture) is (un)jumpered for 3.3V or not? If it is set for 5V, did you remember to connect vccio to +5 instead?

While you were writing this message I was holding in the soldering iron and de-soldering that jumper Looll =P!! Ya, 5V is connected to VCCIO! I'll come back with the results of ur suggestion =P Thx
