This is a quick overview of avr-binutils.


More useful programs:

1. avr-as - AVR assembler.
   AVR options:
  -mmcu=[avr-name] select microcontroller variant
                   [avr-name] can be:
                   avr1 - AT90S1200
                   avr2 - AT90S2xxx, AT90S4xxx, AT90S85xx, ATtiny22
                   avr3 - ATmega103 or ATmega603
   avr2 - default microcontroller.

2. avr-ld - AVR linker.
   To select AVR microcontroller use: `-m <emulation>'
   avr-ld: supported emulations: avr85xx avr1200 avr23xx avr44x4
                                 avr4433 avrmega603 avrmega103 avrmega161 
   avr85xx - default emulation.

3. avr-objdump - display information from object files.
   Don't have any AVR specific option.
   I'm use avr-objdump for disassembling (avr-objdump -S <file>).
   Also interesting result with debugging info:
   avr-as -gstabs <file>.s -o <file>.o
   avr-ld <file>.o -o <file>
   avr-objdump -S <file>

4. avr-objcopy - copy and translate object files.
   I'm use avr-objcopy for extracting .eeprom segment from object file.
   avr-objcopy -j .eeprom --set-section-flags=.eeprom="alloc,load" \
   -O srec <in-file> <out-file>
   To produce Motorolla S-RECORDS use: 
   avr-objcopy -O srec <in-file> <out-file>

5. I don't test: avr-ar, avr-ranlib, avr-nm.
   But IMHO they must work.
