Bpi-r3 serial number

Hy. I tried to get the serial Number of my R3. I tried with lshw, dmidecode but they don’t find. Has someone has an Idea please? :slight_smile:

Afaik there is no serial-number which can be read out. And ethernet-macs are random so also not reliable.

Maybe there is something fixed in efuse which can be used as serial.

Dmidecode imho only works on x86 to read out bios data
