[ECOS] Problem about GNU tool

[HuangQiang]

Hi all:
   I have cross-platform development tools for ARM built.

[a.out ( the app output from arm-elf-gcc)]

I tried the following command:

arm-elf-objcopy -O binary a.out b
// got binary file b

arm-elf-size b

output: File format not recognized.

(Is that binary file format is support by all the GNU tools? why it is all
right in arm-elf-objcopoy while not in arm-elf-size?)

BTW what I am trying to do is to see the section size of the final output
binary file, to see whether it is ok to be put into rom (size problem).)


Thanks

regards!
