You might want to take a look at some of the prebuilt Win32 tools. I am
using http://www.gnuarm.com tools with little problems. As far as the GDB
(Insight actually), ocdlibremote, wiggler setup goes the only real problem I
have is that the 'registers' window cannot be used in Insight - the
registers can be viewed however using the Insight console so this is no real
problem.

I know of people having problems with newer versions of ocdlibremote and
wiggler clones - but this was resolved. Also I had a problem with making a
connection with ocdlibremote but this turned out to be a power up sequence
problem.

The LPC2106 FreeRTOS port documentation page (see link below) has some
instructions on using this setup. May be useful to you but perhaps won't
tell you anything new.

Richard.
