Re: [ECOS] Application build

[Andrew Lunn <andrew dot lunn at ascom dot ch>]

Hi Lin.

The application includes the parts of eCos its needs, not the whole
OS. The linker is clever enough to leave out functions that are not
references.

The configuration of eCos can have some effect on code size. If you
disable a package, you know for sure its not going to get linked
in. This particularly applies to device drivers.

One thing to be aware of. The size of the elf image is very different
from the size of the binary. The elf may be huge, but once you have
turned it into a binary, it will be much smaller.
