Univoque serial number SOM

Apalis iMX6D 1GB IT V1.1B and 2GB version.

Hi, my question is : Does this SOM have a internal memory (never eraseble) for its unique serial number? can it be read? if yes, how?

thanks in advance

Serial number is stored inside Config Block along with other data on separate eMMC partition. Please check this article for some details.
