You compile your application against the set of headers supplied by
eCos and then link it with the ecos library to generate an ELF
executable, which includes all of eCos kernel and all. This is then
loaded directly by GDB or can be converted to a binary or S-Record
image for loading in RedBoot.

You must always use the .ecm file for generating RedBoot. 


I think you need to go back and read the documentation again.
