* avrdude interface for the serial programming mode of the Atmel butterfly
|
|
* evaluation board. This board features a bootloader which uses a protocol
|
|
* very similar, but not identical, to the one described in application note
|
|
* avr910.
|
|
*
|
|
* Actually, the butterfly uses a predecessor of the avr910 protocol
|
|
* which is described in application notes avr109 (generic AVR
|
|
* bootloader) and avr911 (opensource programmer). This file now
|
|
* fully handles the features present in avr109. It should probably
|
|
* be renamed to avr109, but we rather stick with the old name inside
|
|
* the file. We'll provide aliases for "avr109" and "avr911" in
|
|
* avrdude.conf so users could call it by these name as well.
