That's the only one I remember.  We worked through that. :)

I would expect it to work now with correct tools.

I personally have trouble pulling the plug on any port which
has users (this one does) and the CPU is still in production
and recommended for new designs.

I think this is a case where the RTEMS NIOS II users can
make some noise with Altera and have a positive impact for
the free software community.  YOU are an Altera customer
where I am not.  YOU are in a much better position to have
an impact.

If you need support in explaining the issue to someone at
Altera, I am happy to do this.  I'm not trying to be a jerk.
They just are missing out.  Their competitors are doing the
right thing.  Microblaze and Lattice Micro32 are in the
main FSF distributions.
