LPC3xxx port

Has anyone done an LPC3180 or LPC3250 port?

I wondered about the extra effort I might run into with these complex devices. Could I simply start with an ARM9 port?

I cant offer specific advice other than general ARM advice. 

If this is an ARM7 or ARM9 part then you should be able to start with an LPC2000 ARM7 port. Check the setup of the timer interrupt in prvSetupTimerInterrupt() in port.c, the setup of any other hardware in prvSetupHardware() in main (if running an existing demo) and check the start up code configures stacks for IRQ and Supervisor mode at least and that the processor is in Supervisor mode when main() is called.
