Hi Michael,
If I understand your question correctly you are confused about ROM and Flash memory. Flash is treated as RO memory and the address represents where Flash is mapped in a device address space. Does this answer your question?
Hope that helps, Anton

Hi all,
I am getting to know the TF-M, yet I do not understand the following comment and code where ROM (Read Only) is mentioned and its address used to store Code Data (flash_layout.h)!! Can someone help me understand this better? Thanks
