Not true, or at least incomplete.

There is certainly plenty of free support for programming flash.  There is 
Philips own utility and two others that I am aware of for programming the 
flash via the serial port.  And IAP works whether you use GNU or a 
commercial compiler.

As far as debugging goes, it is quite possible to debug GNU code from flash 
either using commercial debuggers or even a wiggler.  The problem with 
using the wiggler for this is at the moment the higher level views don't 
support the use of the HW breakpoints so you can't single step or set 
breakpoints from Insights C source window.  You can use the assembly view 
to do so though.  It's also rather slow.

What I haven't seen in any of the descriptions of ANY available debugger 
for the ARM microcontrollers is one with a decent watchpoint facility.  One 
that would allow you to set a break when a certain value was written to a 
certain location or range of locations for instance (while running at full 
speed of course).
