Lpc2000

Paul,

I am not if your line of questions will lead to something useful, but let 
me try to explain why what I said is relevant to the very real problems 
people are facing with boot loader.

I just checked, KEIL tools include these processor in "ARM" category.

I find they have credibility having been in this business for a while now.

My aim is to point out problems where they exist without fear or favour.  I 
am sorry you take such a narrow view that exposition of a problem that so 
many are facing tantamount to disparaging.

I have explained what I mean by "standards" Paul.  If you do not like it, 
please replace it with "practice" and qualify it with AFAIK.  Happy?

I do not mean to fuel hostility, but why not you tell us from your 
experience which "real" ARM cores you know other than LPC that have no 
means to defend against misbehaving code trashing the flash contents?

Thanks
