this is just a writeup of some tricks I learned from [[User:MariusKintel]]

# installing avr gcc
sudo apt-get install gcc-avr avr-libc

# removing dmx drivers
sudo rmmod dmx_usb

# finding out how big a hex file is on the atmel
avr-size main.hex 

# programming the bootloader
sudo make -f Makefile.usbasp DEVICE=atmega8 HEXFILE=ATmegaBOOT.hex

# flashing arduino
avrdude -F -p atmega8 -P /dev/ttyUSB1 -c stk500 -b 19200 -U flash:w:main.hex 

# reading hex back
 avrdude -F -p atmega8 -P /dev/ttyUSB0 -c stk500 -b 19200 -U flash:r:back.hex:i
