I will assume you are using sources downloaded since May last year. The 
answer is yes. All code derived from eCos code in full or part (even if 
only copying bits from a single eCos file) must be either delivered to 
your customers with the binaries you created (including if the binaries 
are delivered on a device), or put up publically to any third party for 
three years (and your customers informed that it's there).

The only code you can keep to yourself are files containing no eCos code 
in part or full.

Of course we'd be interested in seeing your changes here anyway in case 
they are useful enough to include, and if they are we appreciate it if you 
could contribute them so you can give back a little of what you got from 
eCos :-).

We have actually updated the licence summary on the web site to explain 
all this just today: 
<http://sources.redhat.com/ecos/license-overview.html> ( if it says eCos 
is under the RHEPL then the old versions's probably been cached somewhere 
so use shift-reload/ctrl-refresh to update it)
