> what should i do in make file (MFile) to get this file format. the

modify the example makefile so that it will contain your C & assembler
files and leave the rest of it as it is. Here is a full makefile in case
you don't have it:

Rgrds,

# ===================================================================
# On command line:
#
# make all = Make software.
#
# make clean = Clean out built project files.
#
# make coff = Convert ELF to AVR COFF (for use with AVR Studio 3.x or
VMLAB).
#
# make extcoff = Convert ELF to AVR Extended COFF (for use with AVR Studio
# 4.07 or greater).
#
# make program = Download the hex file to the device, using avrdude. Please
# customize the avrdude settings below first!
#
# make filename.s = Just compile filename.c into the assembler code only
#
# To rebuild project do "make clean" then "make all".

# MCU name
MCU = atmega64

# Output format. (can be srec, ihex, binary)
FORMAT = ihex

# Target file name (without extension).
TARGET = HomeRanger

# Optimization level, can be [0, 1, 2, 3, s]. 0 turns off optimization.
# (Note: 3 is not always the best optimization level. See avr-libc FAQ.)
OPT = 1

# List C source files here. (C dependencies are automatically generated.)
SRC = $(TARGET).c

# If there is more than one source file, append them above, or modify and
# uncomment the following:
#SRC += foo.c bar.c

# You can also wrap lines by appending a backslash to the end of the line:
#SRC += baz.c \
#xyzzy.c

# List Assembler source files here.
# Make them always end in a capital .S. Files ending in a lowercase .s
# will not be considered source files but generated files (assembler
# output from the compiler), and will be deleted upon "make clean"!
# Even though the DOS/Win* filesystem matches both .s and .S the same,
# it will preserve the spelling of the filenames, and gcc itself does
# care about how the name is spelled on its command-line.

# and function names needs to be present in the assembler source
# files -- see avr-libc docs [FIXME: not yet described there]
