No really figure exist.

The footprint does not really depend on the configuration. It depends
on what your application actually uses. Any parts of eCos your
application does not use the linker will throw away. So eCos for a
"hello world" world program which just uses diag_printf will be a lot
smaller than for a complex application which uses many eCos provided
functions. Yet the configuration is exactly the same.
