Peter,
This may be a stupid idea but are you trying to get the
interrupt from your driver initialization routine before
tasking actually starts?
If so, external interrupts on the CPU itself are still
off until initialization switches to the 1st thread.
Probably not it.. there are lots of things that can be
wrong on these complex boards. :(
