Is it possible to use the Arduino as a programmer for an Atmel 32 bit microprocessor? I have tried searching for something and was not able to find anything. If anyone could give any insight that would be much appreciated. On a side note, I am looking to get this microprocessor (http://www.digikey.com/product-detail/en/AT32UC3B0128-A2UT/AT32UC3B0128-A2UT-ND/1769692)
The AT32UCxxx series microcontrollers do not have simple SPI In-System Programming like the smaller 8bit Atmel microcontrollers do. They require ICE-JTAG to be programmed. You can make a AVR Jtag Ice clone. Not sure how compatible that would be with any given Arduino or the Arduino Bootloader though.
But the other way of programming the AT32UCxxx series is... The built in USB bootloader it ships with.. No specialized hardware programmer needed. All you need is a usb cable (or cable + jack) and two series resistors, on top of the all ready required power supply and passives.
This site has the instructions to build a working bare-bones AT32UC3B board from scratch.
