RepRap: Builders

Having set off to build and use the awesome FiveD on Arduino firmware for my minimalist DIY micro-controller board I found we were short a boot-loader. Unfortunately the ATMega1284P whilst being a drop in replacement for the Sanguino's 644P doesn't have a boot-loader ready to go and is arguably a little way off the beaten Arduino Path. I modified the Arduino IDE 22 source for the stk500v2 boot-loader and have managed to persuade this to load and work.

You can get the modified source and a pre-compiled hex file (20Mhz crystal) here.

I guess this is also a do-able upgrade path for owners of through hole Sanguino boards.
