Re: ARM newbie

One of the things that really make these micros valueable is this 
group. All micros have various issues and need for workarounds etc, 
but often you don't knoiw what the problems are or what the 
workarounds are. This goup works great because there are a bunch of 
people that are sharing their problems and solutions which really 
helps to get stuff moving.

There are many toolchains available for ARM. One very cool thing 
about using the ARM's EmbeddedICE JTAG interface is that it is common 
across all ARM7 cores which means that you can feel very confident 
that a toolchain that has proven itself on a different ARM7 project 
will work on LPC21xx. I personally use gcc/gdb + Abatron bdi2000, but 
I can't see why you should not have great success with gcc/gdb + 
wiggler. When you debug a program in flash you have more limited 
debugging (less breakpoints).

I have not tried going into production with an LPCxxx so aI can't 
comment on that.
