The /azone/partition element contains a list of memory partitions that are created with the CMSIS-Zone utility. These memory partitions are based on parent memory definitions specified by /rzone/resources/memories element.
Example
Parent Element | Element Chain | ||
---|---|---|---|
azone | /azone element | ||
Child Elements | Description | Type | Occurrence |
memory | Defines a new memory sub-region that is related to a parent region in the *.rzone file. | complexType | 0..* |
peripheral | Defines a settings for a peripheral. | complexType | 0..* |
The /azone/partition/memory element defines a new memory sub-region that is related to a parent region in the *.rzone file.

Attributes | Description | Type | Use |
parent | The name of the parent region in the related *.rzone file. | xs:string | required |
name | The name of a new memory partition. | xs:string | required |
size | The physical memory size this block allocates. | xs:string | required |
offset | The address offset of this memory partition. If fixed="1" the memory block cannot be re-ordered within the region. | xs:string | required |
access | Access permissions for this memory block. | AccessType | optional |
security | Security attributes for this memory block. | SecurityType | optional |
privilege | Privilege level for this memory block. | PrivilegeType | optional |
startup | "1" specifies that this region is used for the startup code of the application. Default value is "0". | xs:boolean | optional |
fixed | "1" indicates a fixed offset within that region. "0" (default) allows to re-arrange the block within the region. | xs:boolean | optional |
uninit | "1" specifies that this region is not zero initialized during startup. Default value is "0". | xs:boolean | optional |
shared | "1" specifies that this region is used by multiple zones. Default value is "0". | xs:boolean | optional |
dma | "1" specifies that this region is accessed by a DMA controller. Default value is "0". | xs:boolean | optional |
info | Brief description of the memory block. | xs:string | optional |
linker_control | Linker control settings for the memory region. | xs:string | optional |
The /azone/partition/peripheral element defines settings for a peripheral in a related *.rzone file.
