What file, exactly, did you upload as your bootloader?

@nick
I followed the steps here.. http://maniacbug.wordpress.com/2011/11/27/arduino-on-atmega1284p-4/
and followed the ArduinoISP tutorial and burnt that in arduino dumilanove and connected SCK,MOSI,MISO,RESET pins and gave burn bootloader option in IDE with "Mighty 1284p 16Mhz using optiboot" selected as board. I dont know which file exactly though...

I can see why people are enthusiastic about this chip. I've ordered one, and if all goes well, which I doubt, it will arrive before the weekend.

Then I'll try it for myself.

I'll keep you posted.

If possible one those long tutorials for 1284p versions too...

It really does have fantastic potential.  I don't understand why Arduino proper hasn't picked it up for an official board.  I see it as more applicable than the Mega in many cases, and certainly easier to use in DIP format.  For all you get (RAM, raw I/O, various dedicated hardware serial I/O, flash space), it's dirt cheap, too.

+1 for that...  RAM + no. of I/O is what attracted me to it... still now couldnt get it to make it work smoothly though...

I've been saying for ages that the 1284 is a natural for an Arduino and of course a few people are using them (or the 644). I've got a design on the drawing board at present that uses one.

Yes indeed, the 1284 makes a fine board!

"@crossroads which bootloader are u currently using?"

This one, which I think is what sets up with the maniacbug cores.

Good work nick... Seems you to have got it working properly..  Any troubles uploading til now?
I seem to have done all of these stuff mentioned earlier but still my problem still remains... Anyways let me try doing it ditto as u mentioned in your tutorial...
@ nick
Tried uploading larger sketches? and Is the bootloader uploaded by your https://github.com/nickgammon/arduino_sketches/tree/master/Atmega_Board_Programmer same as the one provided by maniacbug?


Sorry Wrong link edited...

Wow, that chip looks big in the first pic! Result of the camera angle I guess.
