Google Coral serial number

I need a unique identifier of my device and on Raspberry PI I could get a serial number of the cpu from the /proc/cpuinfo file. But on Coral there is no serial information in /proc/cpuinfo.

Are there any other ways to uniquely identify my device? What about /etc/machine-id?

    NXP SoC has a unique serial number which could be read from sw.
It is suggested to check IMX8M reference manual for that information.
That approach will require you to add/modify kernel driver to expose that SN via sysfs node.
