Hi Christophe

Thank you for the contribution.

Smartfusion would be a great addition to eCos strength. However in a course of
preparation for processing of your code, while checking your Copyright
assignment, I have noticed that associated copyright disclaimer from STM had
expired 2011-01-12.

As this is hindering inclusion of this port in eCos repository I would ask you
if you could provide a suitable document that will allow inclusion of this
contribution (and possibly your future works) in eCos repository.

Ilija

Hi Ilija,

This work falls outside the scope of my work at STM and is not linked to STM
whatsoever, therefore, I believed my FSF assignment should cover it, unless the
assignment is also limited in time?

Regards,
Christophe

Hi Cristophe,

> assignment is also limited in time?

The assignment is not time limited.

However, unfortunately just because it is outside of the scope of the work at
STM does not mean that STM do not "own" it. Many employment contracts in our
industry say that all work performed, and intellectual property (IP) created,
by an employee is owned by the employer. Alternatively some employment
contracts say that all work and IP created using the employer's equipment
(including your development PC) is owned by the employer. This means if you
entirely created and developed it on your home PC, then that would be fine.

So the question is, what does your employment contract say? I would expect all
employment contracts to say something somewhere about the ownership of IP you
create. And if it says nothing then we may have to assume it _might_ be
covered. Of course if, as you say, it is not related to STM and STM have no
interest, then at least it shouldn't be difficult to obtain the copyright
disclaimer again, as a precaution.

Christophe has been able to get a copyright disclaimer from STM. It looks fine
to me, although it specifically excludes networking stacks. I will have to
consult with the FSF as to whether this could include an ethernet driver -
which could arguably be considered one of the bottom layers of a networking
stack. I doubt it, but I should check. The remainder of the contribution should
be fine to go now though.
