A Memory Space is assigned to a core or an SMP group. Within it, virtual (core) memory accesses are separated from other memory spaces by hardware logic. In each, one application is executing. If a core supports multiple protection levels, specify memory spaces for every protection level in which an application will be executing.

 

To configure Memory Spaces select Debug | Configure Session | SoC | Memory Spaces page.

 

 

Create Default (recommended) - Add Memory Spaces for all cores.

Add - Add a Memory Spaces.

If you're not interested in certain cores, or don't have the Symbol file available, disable the respective Memory Space by unchecking it.

 

Memory Space dialog

Name - Give it a meaningful name.

Location (core, SMP) - Define the location.

Use Level and State - Enable if multiple processes will execute on this core. The following fields specify how the MMU is configured for this memory space.

Mode - Specifies the core state (Exception Level, secure/non-secure):

•VM/HV ID - Specifies the Virtual machine ID - typically written by hypervisor into the VMID register.

•APP/Context ID - Specifies the Process ID - typically written by an RTOS into CONTEXTID/PID register.

Application - Select the application that belongs to the Memory Space.
