[ECOS] Footprint size.

It is better to think of the libtarget.a file has a book library, you dont
take all the books at once and read them at home, instead you take the books
that you need. 

The libtarget.a file contains all of the data and functions that may be
required. It also contains all the debug symbols and extra data that is not
required in the final binary image. Most of this data is removed/ignored
when the final application image is made. 

To get a better feel for the size of the final image you need to create an
application and do an objdump on in. This will tell you how much rom/rom is
used and the locations of the data.

Subject: [ECOS] Footprint size.


Can anyone tell me what they think should be the approximate footprint size
of a basic eCos kernel built on an SH or i386 platform. I am in the process
of porting to a new SH2 processor and target platform, but when I build my
eCos library libtarget.a comes out at 2924kB. This sounds excessively large
to me but I am new to eCos so have no idea of what it should be.

   Can anyone help?


	Many THanks in advance.
