I have a 1-wire temperature sensor/UUID chip in an existing design that I would like to get rid of but I am using the UUID as a serial number. Is there a chip specific UUID somewhere in the i.MX6SL? I know that there is a OCOTP space to put a unique ID for the security sub system, but I am looking for something that will not require special programming at manufacturing.
Alternatively, the iMX6SoloLite could generate a UUID (from what random source?) and write it to the OTP the first time it powers up. Any experience doing this?
