Hej Dinh,
in this case I would just not implement the CPUID interface for that
cpu. The idea of the interface is to abstract mcu peripherals - so if a
peripheral does not exist, we should not try to emulate it on this
level. So let higher levels (e.g. UUID generation) worry about this...
Cheers,
Hauke

Hello RIOT developers,
I am new to the group, then please forgive me for the innocence.
I am doing the cpuid for atmega2560, to finish some part of
https://github.com/RIOT-OS/RIOT/issues/1511.
Some cpus have unique id/or usb id, some don't. Atmega2560 belongs to
the later (please correct me if I am wrong).
Then what is your suggestion to provide the device an ID? I am
thinking about write to its eeprom a 16Bytes number. Any though on this?
Thank for making this great project.
Dinh.
