How to setup avr-gcc and get compiling for an Arduino!
$ yum install avr-gcc avr-libc avr-binutils avrdude
For ATMega168:
$ avrdude -c buspirate -P /dev/ttyUSB1 -x speed=3 -p m168
For ATMega328p:
$ avrdude -c buspirate -P /dev/ttyUSB1 -x speed=3 -p m328p
Terminal mode: -t. Use command part to see detailed part information.
To upload file: -U memtype:op:filename[:format]
Simple makefile: (just produces the .elf and .hex file)
all:
avr-gcc avr.c -mmcu=atmega168 -o example.elf -Wall
avr-objcopy -j .text -O ihex example.elf example.hex
avrdude -c buspirate -P /dev/ttyUSB1 -x speed=3 -p m168 -U flash:w:example.hex
Complex makefile: (produces .o, .asm, .map and .lst files too)
all:
avr-gcc -g -mmcu=atmega168 -c avr.c -Wa,-alh,-L -o avr.o > avr.asm
avr-gcc -g -mmcu=atmega168 -Wl,-Map,example.map -o example.elf example.o
avr-objdump -h -S example.elf > example.lst
avr-objcopy -j .text -j .data -O ihex example.elf example.hex
avrdude -c buspirate -P /dev/ttyUSB1 -x speed=3 -p m168 -U flash:w:example.hex
avr-size example.elf
