Hello,
I'm running Ubuntu 10.10 with and using an Arduino Duemilanove (ATMEGA328). I've used this same board to do a basic LED blinking sketch in windows 7 and everything worked perfectly. Recently, I've switched to Ubuntu and when I tried uploading the same sketch to the board, here's the error that occurs
Binary sketch size: 990 bytes (of a 30720 byte maximum)
