Well, and what about your own eCos startup file (hal_platform_setup.h)?
Did you manage the LPC PINSEL registers correctly? I see that Jani
Monoses, for example, didn't overload his own startup files by any extra
lines ;) Observe arm/lpc2xxx/*/current/hal/include/hal_platform_setup.h
files, for example. It's possible you have to force Debug/Trace pinouts
assignment in your own eCos platform startup file.

That already has contained that February fix.

At first, I would suggest to check your eCos startup code (platform
startup, certainly).
