I am working on a custom device for which I customized the Android port of a TechNexion i.MX8 SOM.
During production, our factory requires that production data (order number, serial number, and other production related information for traceability) be stored into the device.
I can store all of this in a file but my concern is that this production data may be lost after an OTA update.
Is there a mechanism in place to store permanent data (such as production data) to make sure that this will never be erased?
Thanks in advance.
