Well I have the 1284p chips.
I have one of the chips fitted to a breadboard.
I have an ISPtinyUSB and AVRISP mk II.
I have a firmware for the 1284p
I have the USB driver libusb-0.1.12
if I try to use AVRDUDE I get this fault:
MacbookPro:~ darren$ avrdude -v -patmega1284P -cusbtiny -Pusb -U lock:w:0x3F:m
avrdude: Version 5.10, compiled on Apr 30 2011 at 06:16:16

avrdude done. Thank you.
I have tried to install the USB driver but have had no luck whatsoever!
I have tried to install fink in order to install the USB driver but fink seems to have installed but I cannot run it!
I am having a right nightmare trying to get this to work!
I bought a AVRISP mk II today to try and use that rather than the ISPtinyUSB that I did have and I have also downloaded AVRstudio.
It's not working though.......
