Is there any accessable information on the colibri-imx6 processor, which is uniq to each CPU and not changable?
First thought was to use the CPU’s serial number as stated here .
But as described here and here, you can change the MAC adress via the bootloader or the sysinfo library. This would change the SN, since it is tied directly to the MAC address. ( here ) - or have I misunderstood something?
The reason is, we’d like to prevent copying of our product by connecting the application to a unique information stored on each CPU.
