Download an ELF file to flash? Is it executable? (SAM7X)

I'm using a SAM7X micro-controller and need to download the binary file to the flash.

Until now I've done this with my IDE (EDGE) while I was in debug mode.
Now, I want to download the binary to the flash using the SAM-BA software, because that my IDE gives me a not descriptive error when I try to run the program.

An ELF file gets created as a result of a project build.
Do I need to download the ELF file to the flash,
or convert the ELF to EXE and then download the EXE to the flash?

Thank you

Hello, if i am right, you have to convert it to exe.
I am still trying to make sense of the makefile and all it's commands.

I found some information here.

http://en.wikipedia.org/wiki/Executable_and_Linkable_Format

This what is written in the make file i use :

Code:

RAM: $(OBJS) $(PROJECT)_ram.elf $(PROJECT)_ram.hex

ROM: $(OBJS) $(PROJECT)_rom.elf $(PROJECT)_rom.hex

%o : %c
   $(CC) -c $(CPFLAGS) -I . $(INCDIR) $< -o $@

%o : %s
   $(AS) -c $(ASFLAGS) $< -o $@

%ram.elf: $(OBJS)
   $(CC) $(OBJS) $(LDFLAGS_RAM) $(LIBS) -o $@

%rom.elf: $(OBJS)
   $(CC) $(OBJS) $(LDFLAGS_ROM) $(LIBS) -o $@

%hex: %elf
   $(BIN) $< $@

If you want the complete makefile , i can post it if you want.

extract your binary from ELF:

objcopy -O binary yourfile.elf yourfile.bin

and that would be "arm-elf-objcopy" for gnu arm.
