There is an idea to protect Arduino Zero from copying. There is a clone on the SAMD21G18A processor.
With the help of the J-link programmer, using Microchip Studio 7 in the security section, I set the protection.
After power off and reboot, I don't see any security changes. The controller path is read and copied.
Does this controller have the same copy protection capability as the AVR family?
I was lucky. The solution was found.
The method really works.
