Memory footprint

Hi mountain8848,

vmlinux is an elf file and it contains lots of extra linker sections like comments and debug

information that are not allocated space in your memory. For example, my vmlinux size is

about 11 MB, but the allocated memory (in the elf) is about 1.3 MB.

You can get a better sense for the amount of memory your kernel code will occupy

by stripping the elf:

$ nios2-elf-strip vmlinux

Or you can just use objdump and add up the sections that have the ALLOC attribute.

But note that this does not account for any dynamic memory that may be needed.
