Whether non-volatile storage space similar to EEPROM exists in jetson nano

Hello, @mdegans, @Andrey1984

Can mtd be added in addition to the mtd currently mounted as the root file system?

I want to set a minimum partition to store our information on the jetson nano.
Jetson nano has an eeprom, but I know it’s quite small.
Is there any space on the jetson nano to store the information regardless of the os being deleted, like eeprom?

I remember there is a script created by @mdegans for emmc partitioning, can you tell me the location?

Regarding what @JerryChang said below, is it possible to make some of emmc’s partitions only for our products?
I want to know how to make it.

Thank you.
