This should go to the avrdude-dev list instead of directly to me.

Subject: avrdude butterfly

hi,

I just playing with avrdude and the butterfly part to upload programms
via bootloader

I changed my bootloader to support 38400 baud on my atmega16

the butterfly part of avrdude does not support 38400 baud
so, I added some lines in butterfly.c and butterfly.h
maybe, you want to add it in the next release of avrdude
I currently use "avrdude 4.4.0" for linux

here my little modification:
butterfly.c:
line 342:
pgm->fd = serial_open(port, 19200);

my change looks like this:
if(!pgm->baudrate) pgm->baudrate=DFLT_BAUDRATE;
pgm->fd = serial_open(port, pgm->baudrate);

with this, you can use the -b paramter to adjust the baudrate
if -b is not given the DFLT_BAUDRATE is used

butterfly.h:

#define DFLT_BAUDRATE 19200


best regards

marco
