Subject: [lpc2000] JTAG debugging tools

Main advantage is that the debugger is much more comprehensive and easier to 
use. Rowley use the gcc tools with their own IDE and debugger.

That is really a function of the debugger. The Rowley debugger works with 
programs in flash, even with a Wiggler or Wiggler clone.

Speed! They are much faster than a Wiggler (if the Amontec unit is used in 
Raven mode).
