Sorry for my rudeness, but I do not believe copy protection, or any form of immoral Digital Restriction Management is able to be a solution to count products.

I don't protect my source. I gave the source to customers. I just want to protect binary. Customer doesnt know how to build.
In a business, customer dont tell the correct production amount as what is wrote in the contract. It is not my fault.

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?
