AVRdude
AVRDUDE is a command line tool to program AVR chips. It runs in the background of the Arduino IDE. Sometimes it is necessary to erase a chip or set the fuse bits that's when the AVRdude comes handy.

avrdude -C <arduino-ide-folder>/hardware/tools/avrdude.conf -v -p <partno> -c <programmer> -P <port> -b 115200 -U flash:w:<full_path_to_hex>:i
| -C <config-file> | specify location of configuration file | ||
| -v | verbose output-v, in case you want to debug something | ||
| -p <partno> | specify AVR devicee could be atmega328p or m8u, … | ||
| -c <programmer> | specify programmer type could be stk500v1 or stk500v2, … | ||
| -P <port> | specify connection port could be /dev/ttyACMx (Linux $ ls /dev), or COMx (Win) | ||
| -b <baudrate> | override RS-232 baud rate | ||
| -U <memtype> | :r | w | v:<filename>[:format] |
memory operation specification, the <memtype> is either flash or eeprom r|w|v means r (read) w (write) or v (verify) <full_path_to_hex> is the hex filename and location
ATmega32U4
To erase the chip:
sudo avrdude -p m32u4 -c stk500v2 -P /dev/ttyACM0 -e -F
ATmega328p
To erase the chip:
sudo avrdude -p m328p -c stk500v2 -P /dev/ttyACM0 -e -F
ATmega168
set the fuse bits:
avrdude -c stk500v2 -p m168 -P /dev/ttyACM0 -B 6 -v -U lock:w:0x3f:m -U lfuse:w:0xff:m -U hfuse:w:0xdf:m -U efuse:w:0x0:m
Atmega8u2
It is the chip for serial to USB on the Arduino Uno and on the Usb2Serial board.
<!> On the Arduino Usb2Serial Light Board the ISP header is marked wrong, pin 1 is the nearest one to the Atmega8u2 chip <!>
Burning Serial to USB:
sudo avrdude -C /usr/share/arduino/hardware/tools/avrdude.conf -p m8u2 -c stk500v2 -P /dev/ttyACM0 -b115200 -U flash:w:Arduino-usbserial-uno.hex:i
Burning Serial to Midi:
sudo avrdude -C /usr/share/arduino/hardware/tools/avrdude.conf -p m8u2 -c stk500v2 -P /dev/ttyACM0 -b115200 -U flash:w:MIDI_Firmware/Arduino-usbmidi-0.2.hex:i
Burning Serial to USB on Sparkfun Atmega8u2 Breakout:
sudo avrdude -p m8u2 -c stk500v2 -P /dev/ttyACM0 -U flash:w:Arduino-usbserial-uno.hex:i
