/azone/partition element

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

<partition>
<memory parent="Flash_NS" name="ROM_NS" offset="0x00000000" size="0x40000" fixed="1" access="rx" info="application code" />
<memory parent="Flash_S" name="ROM_S" offset="0x00040000" size="0x40000" access="x" info="boot code />
<memory parent="SRAM1_NS" name="RAM_NS" offset="0x00000000" size="0x20000" />
<memory parent="SRAM1_S" name="RAM_S" offset="0x00010000" size="0x20000" />
</partition>
