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?
