<div class="textblock"><p>Every CMSIS-Zone project consists of one or more zones. The basic flow to create zones is as follows:</p>
<ul>
<li>In case of multi-core devices, create a zone for each processor.</li>
<li>Then create at least one zone for each processor to be able to assign memories and peripherals. If your device contains Arm Cortex-M cores supporting TrustZone for Armv8-M, create a secure and a non-secure partition for each of these cores.</li>
</ul>
<h1><a class="anchor" id="zTUICreate"></a>
Create Zones</h1>
<p>To split a multi-processor system into single-processor sub-systems, you need to create new zones. Switch to the <b>Zones</b> tab and click the <b>Add new zone</b> button:</p>
<div class="image">
<img src="AddNewZoneButton.png" alt="AddNewZoneButton.png"/>
</div>
<p>In the new window, you need to specify a name for the zone, select the applicable core, and choose the security level (secure/non-secure).</p>
<p>In the <a class="el" href="zTEMusca.html">Musca</a> example, a new zone called "CM33_0" was created and attached to processor core 0 without any security attribute (not specified):</p>
<div class="image">
<img src="NewZoneCM33_0.png" alt="NewZoneCM33_0.png"/>
</div>
<p>Similarly, an additional zone called "CM33_1" was created and attached to processor core 1, without security attribute.</p>
<p><b>Save</b> your settings:</p>
<div class="image">
<img src="SaveButton.png" alt="SaveButton.png"/>
</div>
<dl class="section note"><dt>Note</dt><dd></dd></dl>
<p>Adding zones only works for the currently opened <a class="el" href="zoneFormat.html#azone">.azone</a> file. The information about the zones is stored in the <a class="el" href="xml_zones.html">/azone/zones element</a> element of the *.azone file. </p>
