Hi Zheng,
it is really hard to do that. I guess you'll need to have platform support for such a feature. Maybe you could ask Christopher Tarnovsky about such technologies (chris.tarnovsky@ioactive.com). He is a kind guy and an expert when it comes to security chips/technologies on the hardware level :) .
Best Regards Zheng

Hi, All, Is there any way to protect the binary image in flash chip from being copied? Once the customers gets the image, they can produce millions of board and do not tell me. I just want to know the amount of the mass production.
OTP seems to be a way, but it is not 100%. The data in OTP is readable and can be copied to a new chip's OTP erea.
Do you guys have any more suggestion?
Zheng
