[avr-chat] Avrdude fails to connect to my Dragon...

[Vincent Trouilliez]

Hi people,

So far I have been using avrdude succesfully with my crappy DIY
parallel cable, using ISP.
I have recently got a lovely little Dragon (a marron one not green, but
still useful ! ;-).

I did nothing particular but plug it on my computer, and apparently
Linux picked it up no problem, as far as I can understand:

However when I modified my usual avrdude command line to suit, by
replacing -c bsd by -c dragon_isp, I got that in return:

avrdude: ser_open(): can't set attributes for device "/dev/parport0":
Inappropriate ioctl for device

I clearly specified to use the dragon not the parallel port cable
anymore (and I don't have any avrduderc file that might override that),
so I don't understand why it's still talking/complaining about the
parallel port....

Any clue ?

Yes, I am very frustrated not to be able to enjoy this lovely Dragon
that's so much cuter than my old crappy DIY cable ! ;-)
