nRF9160DK Memory allocation

[Gioele]

Hi!
I would to know how to partition the memory of the board and how to make that secure and trusted.
Once I did that there is a way to save some information in that portion of the memory accessible only to the authorized users?

Ok, but with memory, I'm referring to a physical part where I can store some data. Also here there is the difference between secure and non-secure? And I must say that there are months that I'm studying SPM without understanding clearly this difference.

Please build with nrf9160dk_nrf9160ns and type "ninja partition_manager_report" to get the memory layout regarding build/partitions.yml as my previous reply.

Have a look at ARM TrustZone.
