amassa@cts> As far as my problem goes, the memory region in the

amassa@cts> MEMORY { ram : ORIGIN = 0, LENGTH = 0x400000 rom : ORIGIN

Which makes the error message rather confusing since it complained
about not being able to fit in 32kB - but neither block has such a
small length according to the above.

amassa@cts> And I tried a build from scratch on a different system and

Try this:

thinktwice:> ecosconfig new mbx stubs

And try to get the latest sources from CVS. You were using 1.3.1
sources, right?

amassa@cts> One thing I did try is changing the clock speed.  My MBX

amassa@cts> Do you know of some problem using the 40 MHz selection?

amassa@cts> Has a stub been tested on the 40 MHz MBX board?

I can build for both 40 and 50 MHz configs, and I know we have boards
of both types running eCos.
