Hi all,
I wanted to modify makefile so that I have the freertos.out file along with the freertos.bin

Some guidelines on how to obtain the freertos.out file would be really helpful. I need the .out file for debugging purposes for AT91SAM7256 processor. Currently I am using eclipse.

Thanks in advance,
Monish

You need to use the objcopy command that comes with GCC. Take a look at the binutils manual which you will find somewhere on the gnu.org site. Or simply type "arm-none-eabi-objcopy /?" or "arm-elf-gcc /?" depending on the version of gcc being used.

Thanks Edwards. I referred the binutils manual in GNU.org but I am still skeptical of the usage considering that I am not an expert. So here is the Makefile.

# **********************************************************************************************
#                            FLASH PROGRAMMING
#
# Alternate make target for flash programming only
#
# You must create a special Eclipse make target (program) to run this part of the makefile
# (Project -> Create Make Target… then set the Target Name and Make Target to "program")
#
# OpenOCD is run in "batch" mode with a special configuration file and a script file containing
# the flash commands. When flash programming completes, OpenOCD terminates.
#
# Note that the script file of flash commands (script.ocd) is part of the project
#
# Programmers: Martin Thomas, Joseph M Dupre, James P Lynch
# Modifies:    Gabriele Brosulo, 22/08/2007
# **********************************************************************************************

# specify output filename here (must be *.bin file)
TARGET = freertos.bin

# specify the directory where openocd executable and configuration files reside
OPENOCD_DIR = ‘/usr/local/OpenOCD/src/’

# specify OpenOCD executable (pp is for the wiggler, ftd2xx is for the USB debuggers)
OPENOCD = $(OPENOCD_DIR)openocd

# specify OpenOCD configuration file (pick the one for your device)
OPENOCD_CFG = OpenOCD/at91sam7s256-wiggler-flash-program.cfg

# program the AT91SAM7S256 internal flash memory
program: $(TARGET)
    @echo "Flash Programming with OpenOCD…"            # display a message on the console
    sudo $(OPENOCD) -f $(OPENOCD_CFG)                    # program the onchip FLASH here
    @echo "Flash Programming Finished."                    # display a message on the console

So is
-freertos.out : freertos.out
-$(OBJCOPY) freertos.elf -O srec freertos.out

The right way to get a .out file in our Makefile?

Thanks,
Monish
