This bootloader is written to emulate Atmel s well-known STK500 AVR development board. The STK500 uses a block transfer protocol to quickly program AVR processors using a standard serial port connection and ordinary RS-232 signaling. With this bootloader installed, you will be able to program your processor from Atmel AVR Studio, just like you would if you were using an STK500 board. For most processors, a complete programming cycle takes 5-10 seconds.
