9.1.3. Considerations when using memory maps

When working with memory mapping, you must be aware of the following:

Considerations for targets that support TrustZone technology

For targets that support TrustZone® technology:

  • The memory map shows both the Secure World and the Normal World memory maps.

  • Specify the TrustZone world for a memory region (the default is Secure). How you do this depends on the method you use to create the map entry:

    • When using the Create Map Entry and Edit Map Entry dialog boxes to set up temporary memory map entries, prefix the address with either S: or N:.

    • When setting up memory map entries in a BCD file, set the Tz_world setting to the appropriate value and specify addresses in the memory block without the S: or N: prefix.
