Re: impact of boot loader bugs on CRP

2006-02-19 by Jayasooriah

Hello,

The emails I have received on CRP issues suggests there are people who 
follow the discussions in this forum that are quite seriously concerned at 
what role Philips is playing in killing the CRP thread (see attached poster 
by Robert).

Of particular concern is the Command String Interpreter (CSI) bug that I 
said crashes the boot loader.  As explained before, I discovered this by 
quite by accident, upon examining boot loader code version 1.52 on LPC 2105.

I have been asked to clarify the status of this bug on parts with CRP feature.

A similar CSI bug exists in boot loader version 1.64 on LPC 2292 that am 
now working with.  I am able to exploit this bug to crash the boot loader 
even with the CRP feature enabled.

I do not wish to frustrate the jet lagged Robert more than I already 
have.  So I will not post details here.  However, if you are concerned 
about what this bug may mean to protection of your IP using CRP feature, 
and/or would like a custom boot loader that is free of such bugs, and one 
that can meet your compliance requirements, please feel free to get drop me 
an email.

No responses on this forum please -- we must learn to keep Robert's noise 
(things Robert does not like to hear) down so that he is happy and will 
continue to participate in "great technical discussions" by his "many fine 
engineers" in this forum.

Kind regards,

Jaya
