Hi
Bob,
Rest assured
that flash protection works and is endorsed by Philips; they are working on the
docs AFAIK. . See the FAQ on our site for some important
information:
http://www.ashling.com/support/lpc2000/knowledge_base.html. In particular, the section "How do I enable LPC2000 Flash Read
protection?
"

The reason I am interested in looking at other parts are because of Atmels bad silicon on the ATmega32,64, and 128 parts and Atmels poor response to customers problems. The parts don't work at 16 MHz and sometimes down to even 10 or 12 MHz when warm. http://www.avrfreaks.net/phpBB2/viewtopic.php?t647 Thanks, bob --- In , "douglasbolton" <doug@c...> wrote: > --- In , "bobtransformer" <bgudgel@e...> wrote: > > > > Hi folks...

Yes, thank you... I found that link easily on Google, but I wondered why Philips would now have that very important information in their documentation or even on their web site. I believe I had seen a message from Philips regarding the issue though on some other web forum. thanks, bob --- In , "Hugh O'Keeffe" <hugh.okeeffe@a...> wrote: > Hi Bob, > > Rest assured that flash protection works and is endorsed by Philips; they > are working on the docs AFAIK. .

Hi all, Out of curiousity, I've put in an ORG directive to place 0x87654321 at address 0x1FC in Flash to see if the code protection works. Reading the code back and comparing with Bootloader is succesful - thus the part isn't protected. I'm using an LPC2119 Bootloader ID = 1.6. Anyone know what I'm doing wrong ? I thought these parts had protection in there ? -- Kris |

Sorry your bootloader version must be 1.61 or higher. Andreas |
