[avr-chat] arduino upload problem

[Renato]

Hi, I'm trying to upload a sketch to an Arduino Duemilanove with
avrdude but I'm getting the error pasted below. I really don't have a
clue of the avrdude command syntax, it was generated by the Arduino
IDE - sorry for that. But I searched a lot for this error and couldn't
find an answer. The board is connected at /dev/ttuUSB0. 

I'm on Archlinux, up to date. The uploading works ok with other systems so I 
think it isn't
a hardware problem.

Also, this command returns nothing, so the board is not being used by
another process:
sudo lsof |grep ttyUSB

Any help is very much appreciated.
