256K...384K.

If you are looking at a multi-mega/gigabyte .bin file, it is usually 
because your memory map has a *large* empty space in it.  This is 
typically due to interrupt vectors and the executable portions being 
widely separated.  When creating the .bin file, the Makefile fills empty 
spaces with 0xFF (IIRC).

You can use ${CROSS_COMPILE}objdump -h (and other options) to see what 
is in your .elf file and where things are located.
