I would be more interested if the question was related to CRP or 
Flash Security as the subject reads.  Your issue is with a version 
of the boot code that runs on a device that doesn't support CRP.  By 
the way, it is the version in my 2106, as well.  I can't say I much 
care how the boot code works, as long as I can load the flash with 
the factory provided utility.  I know I don't have CRP and don't 
care.

For the 2294, the current boot code is at least ver 1.63 and CRP 
wasn't implemented until ver 1.60.  Is there a T command in the 
latest version of the boot code for the 2294?  If not, the question 
above is irrelevant.  And that is the issue - there is not one shred 
of evidence that the boot code, as implemented, doesn't work as 
described in the datasheet and errata.

You have stated that a software approach to security was not 
acceptable for your application.  If this is your position, you will 
never be satisfied with Philips.  Why pursue it?
