NP - it is a community effort after all :-)

We have the opposite view - our test farm finds errors which normal user
and field testing does not catch.  I think the earlier you get the
toolchain into the test farm the better because you will at least
minimise the user and field regression testing needed when you fix
issues thrown up by the farm.

We are happy to throw as many toolchain candidates as needed into the
test farm, with the only restriction being the bandwidth each board runs
the tests, so don't feel you have to hold back and use the farm for
final verification. Our test farm has thrown up far more eCos bugs and
toolchain issues than the rest of the community has to date.

That is interesting.  However the two boards I suggested are ones we
physically have so can build and run tests for and are conveniently
currently located in our test farm. We don't have a Freescale K70.  The
publicly available boards we do have can be found at
http://www.ecoscentric.com/ecos/ecospro_tab.shtml, although not all may
be available in our test farm. Is there board in this list you may think
may be better for testing for which a public eCos BSP exists?
