Since they didn't supply source with the product, they must include a 
written offer to supply the source, as per GPL clause 3. If there was no 
such offer, that is already a violation.

You, and in fact anyone, is entitled to the GPL covered source code for 
any binary containing GPL'd code, if it didn't already come with sources. 
Which is indeed the case here.

So, in other words.... yes :).

I assume you have given them a reasonable time to respond, and approached 
the correct e-mail address? May I suggest looking at 
http://ecos.sourceware.org/ml/ecos-patches/2002-11/msg00082.html and 
talking to that guy directly. He may be more receptive.

Failing that, write a letter, by which I mean a physical one. E-mail is 
not a formal means of communication in many countries unfortunately. Tell 
them that you have informed the copyright holders (of which I am one) and 
that the copyright holders are also awaiting Inventel's response to you 
with interest.

If it's reached the stage of writing a letter (rather that talking to 
Xavier Debreuil) then you might consider upping the ante by highlighting 
to them section 4 of the GPL:

"  4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License.  Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License."

In other words... if they do not comply, they will be forced to withdraw 
*and recall* their product entirely.

But to be honest, I suspect more cock-up than conspiracy. Ignorance of the 
GPL requirements is the usual reason for non-compliance. There's probably 
no need to go out all guns blazing yet.

Note that they may well have published some of their patches on the 
ecos-patches list, as evinced by the above link. But that still doesn't 
absolve them of their obligations to give you the offer to obtain the 
source code. BTW, note that due to the special GPL exception clause with 
eCos, they are only required to provide code directly or indirectly 
derived from eCos/RedBoot. This may or may not be the code used to 
generate the entire binary.

Ultimately yes, if necessary by going to court. That's very expensive and 
best avoided if it can be done by another route. But anyone can approach 
them and "remind" them of their legal obligations.

Please let ecos-maintainers [@] ecos.sourceware.org know how you get on.
