Lpc2000

I fought through a very high-stress, fast development, without being
very familiar with the CPU or with the tools, and delivered prototypes
yesterday.  As far as these things go, this was a very good outcome
given the situation.  Here is what I used:

	1. Nohau JTAG ARM Emulator
	2. GCC 3.3.2
	4. The book, "Embedded System Design on a Shoestring" (ISBN
0750676094)
	5. This Yahoo Group

These tools work, although I cannot say whether they are the best
choice.  I simply didn't have time to put a lot of research into
anything before I bought them, and when I was looking (late December) I
had trouble even getting vendors to call me back.  Some things about the
Nohau bug me -- programming on-chip flash and stepping between ARM &
THUMB are cumbersome -- but I worked around both issues and it was a
productive tool.  In this case, it all worked out.  Tooling costs were
about $1K.

James,

I am sorry to hear that you had problems with our debugger. However:

(1) I beleive you were not using LPC2100. We have excellent built in 
support for flash programming of LPC21OO. 

We do support external flash, however the current support is, I 
agree, cumbersome. A new upcoming release will address that.

(2) We do handle ARM/Thumb transitions - tested with ARM ADS, SDT, 
RealView, HI-TECH ARM-C, IAR EWB, GCC 2.95 and GCC 3.2. I have not 
heard about this before. I will ask in a private email. (For GCC and 
IAR, only on c-level).

It is a good product, well worth the cost.  And Nohau support returned
my emails late on a Saturday afternoon, even though the "show stopping
problem" turned out to be me.

Often, projects with a steep learning curve are not much fun, and this
was one of those.  BUT I DID COMPLETE THIS PROJECT ON TIME WITH THE
NOHAU DEBUGGER.
