原题： Burning the Bootloader without external AVR-Writer

FT232RL BitBang Mode AVR-Writer
 

FT232RL is an USB-Serial bridge on an Arduino Dicimila/NG/Duemilanove PCB. It has the function to manipulate each signal pin directly. It's called BitBang Mode.

"avrdude-serjtag" is AVR-Writer software developed by Mr.Suz. It include the function to control FT232RL BitBang Mode.

If we use "avrdude-serjtag" we can burn the bootloader by Diecimila itself.

I describe below the method. on Windows-XP.

Attention!!!

If you want use "avrdude-serjtag" on Linux or Mac OS, you must remake ( patch, reconfigure and recompile) it.

There are useful projects. avrdude by FT245R/FT232R(Linux) and BitBang Mode AVR-Writer on Mac (Translated to English by Google.) These projects made a way to BitBang Mode AVR-Writer on Linux and Mac !!!

Of course, if you use Windows in Vmware on your Linux or Mac OS, you can run "avrdude-serjtag(windows version)".

Modify the Dicimila

There are four pads written as X3 near FT232RL on a Diecimila PCB. (These pads are connected to the control pins of FT232RL.)
Remove the solder of these pads and insert a pin-header. And soldering it.
