Hi

We have a real time clock chip on our design which has a

Unique, factory-lasered and tested 64-bit registration number (8-bit family
code + 48-bit serial number + 8-bit CRC tester) assures absolute
traceability because no two parts are alike

we used this to identify each board, not sure if you have anything similar
that you could use.

Some Intel Strata Flash (for instance, J3 series) has 128bit Protection
Register.
It can be used as a kind of serial number.
Check Intel Strata Data Sheet.

If PXA255 Unique ID means serial number, then NO.
If that means Processor ID, then Yes.
(Use Coprocessor 15 Register 0 - ID Register)
