arm - how to check endianness of an object file

Question

Using objdump, how do you check if an .obj is little- or big-endian?

you must clearly mention about the environment where your building. Windows is not mentioned in the question. Are you building arm on your windows machine? — danglingpointer, Nov 29 '17 at 13:19

So if you run objdump -d <filename>, you should see at the top of the disassembled code a line that is in this format:

<filename>: file format (string that contains littlearm or bigarm)

I assume that littlearm implies little endian and bigarm implies big endian.

Simple approach is to use the file command that will give you the result what you expect.

$file your_object_file.obj
example output
$firmware.img: Linux jffs2 filesystem data little endian

Add that in your question you want this to do in Windows. – danglingpointer Nov 28 '17 at 19:46
