[ECOS] eCos port for Xtensa- any update?

[Payam Torab]

Hello all,

I am interested in running eCos on a Tensilica core; the last posting I
found in the discuss archive goes back to June 2005 (pasted below). Is there
any update on this? Has anyone run eCos on Tensilica products (Diamond or
Xtensa)?

Thanks,
Payam

Tensilica supplies a working version of Redboot, based on the old 1.1
code.  At my previous company (www.stretchinc.com) I ported their code
to the latest ECOS CVS.  I finished most of the port (and fixed a ton
of bugs :P) but never had time to get ECOS running.  I suspect it
would not be terribly difficult, assuming you don't run into serious
tool issues with C++.  Neither Tensilica nor Stretch submitted their
changes back, but if you are Tensilica Licensee, you probably have
their code anyhow.

The latest compiler from Tensilica is no longer gcc based, instead
they have a compiler based on the Open64 compiler from MIPS, so there
may be some issues with C++  if you  do not have the gcc compiler for
Xtensa.
