Atmega2560
This chip is typically found in the “Arduino Mega” and is very common in 3d printer boards.
To flash the bootloader itself use something like:
wget 'https://github.com/arduino/Arduino/raw/1.8.5/hardware/arduino/avr/bootloaders/stk500v2/stk500boot_v2_mega2560.hex'
avrdude -cavrispv2 -patmega2560 -P/dev/ttyACM0 -b115200 -e -u -U lock:w:0x3F:m -U efuse:w:0xFD:m -U hfuse:w:0xD8:m -U lfuse:w:0xFF:m
avrdude -cavrispv2 -patmega2560 -P/dev/ttyACM0 -b115200 -U flash:w:stk500boot_v2_mega2560.hex
avrdude -cavrispv2 -patmega2560 -P/dev/ttyACM0 -b115200 -U lock:w:0x0F:m
To flash an application use something like:
avrdude -cwiring -patmega2560 -P/dev/ttyACM0 -b115200 -D -Uflash:w:out/klipper.elf.hex:i
