I got a couple of ExtraCore boards. I would like to upload them with the DueMilanove board (as FTDI with microcontroller removed)
I connected the Extracore board as a Pro Mini (5V, GND, RXi, TXo, DTR). Also tried to connect the Reset pin straight from the Duemilanove board (instead of DTR) But cannot get it to upload a sketch (communication is working)
I have never used the Optiboot loader before.
Any ideas? Can the Duemilanove board handle controllers with Optiboot loader ?
