<p>These files can be used in any IDE to create the final application. In the following, the usage in Arm Keil MDK is described.</p>
<h1><a class="anchor" id="zTELPC55_MDK"></a>
Using the MDK project</h1>
<p>The example project can be loaded, built and debugged in µVision by performing the following steps:</p>
<ol type="1">
<li>Navigate to Examples/LPC55S69/MDK</li>
<li>Open the multi-project workspace hello_world.uvmpw</li>
<li>Optional: Update the generated files by executing the copy_gen.bat scripts in hello_world_s\mdk and hello_world_ns\mdk folders.</li>
<li>Run the batch build in MDK. Both projects, hello_world_s and hello_world_ns need to be compiled in order.</li>
<li>Set hello_world_s as active project.</li>
<li>Connect the LPC55S69-EVK using a Micro-USB cable at Debug Link (P6).</li>
<li>Open <b>Options for Target - Debug</b> and make sure that the CMSIS-DAP ARMv8-M Debugger is selected and the LPC-LINK2 is used.</li>
<li>Optional: Open a serial terminal program (i.e. PuTTY) on the virtual serial port provided in parallel to the debugger (e.g. USB Serial Device). Configure the port to 115200/8N1.</li>
<li>Launch a debug session and watch the serial console output: <div class="image">

<div class="image">

<div class="textblock"><p>This single processor demo application shows how to do the <a class="el" href="UseCases.html#UseCase_TrustZone">TrustZone Partitioning</a>. It is split into a secure and non-secure part. Using CMSIS-Zone, it generates:</p>
<ul>
<li>A header file that contains #defines to control the various linker scatter files (and might be used in other parts of the application).</li>
<li>The SystemIsolation_Config.c header file that contains memory protection controller (MPC) and peripheral protection controller (PPC) and related interrupt setup.</li>
<li>The partition_gen.h header file that contains the secure attribution unit (SAU) setup and the NVIC configuration for secure/non-secure.</li>
</ul>
<p>The application itself shows how to implement calls between the secure and the non-secure part.</p>
<h1><a class="anchor" id="zTESTM32L5_Eclipse"></a>
Using the CMSIS-Zone project</h1>
<ul>
<li><a class="el" href="zTExamples.html#zTExImport">Import</a> the project "Examples\STM32L5\Zone" into the CMSIS-Zone utility</li>
<li><a class="el" href="zTUI.html#zTProjEx">Open</a> the STM32L5.azone file</li>
<li><a class="el" href="zTUIGenerate.html">Generate</a> the related output files</li>
</ul>
<p>The STM32L5.azone file of that project has the following configuration settings:</p>
<ul>
<li><a class="el" href="zTUIZonePart.html#zTUICreate">Added the zones</a> <code>blinky_s</code> and <code>blinky_ns</code> </li>
<li><a class="el" href="zTUIMemPerRes.html#zTUIMemAdd">Created the memory regions</a> <code>CODE_NS</code>, <code>CODE_S</code>, <code>Veneer</code>, <code>DATA_NS</code>, and <code>DATA_S</code> </li>
<li>Selected various memory regions and peripherals for using in the different zones.</li>
</ul>
<div class="image">
<img src="STM32L5_zones.png" alt="STM32L5_zones.png"/>
</div>
<p>The zones use different Flash and SRAM regions for code and data, but share Flash configuration registers. Peripherals, such as the system and IO configuration, as well as an UART are available in the secure world only. To generate the output, click on the <a class="el" href="zTUIGenerate.html">Generate</a> button in the Zone Editor tool bar. This creates the following files in the <code>ftl_gen</code> directory:</p>
<table class="doxtable">

<tr>

<p>These files can be used in any IDE to create the final application. In the following, the usage in Arm Keil MDK is described.</p>
<h1><a class="anchor" id="zTESTM32L5_MDK"></a>
Using the MDK project</h1>
<p>The example project can be loaded, built and debugged in µVision by performing the following steps:</p>
<ol type="1">
<li>Navigate to Examples/STM32L5/MDK</li>
<li>Open the multi-project workspace blinky.uvmpw</li>
<li>Optional: Update the generated files by executing the copy_gen.bat scripts in blinky_s\mdk and blinky_ns\mdk folders.</li>
<li>Run the batch build in MDK. Both projects, blinky_s and blinky_ns need to be compiled in order.</li>
</ol>
<h1><a class="anchor" id="zTESTM32L5_MDK_Setup"></a>
MDK project setup</h1>
<p>The multiproject workspace contains the secure <code>blinky_s</code> project and the non-secure <code>blinky_ns</code> project:</p>
<div class="image">

<div class="textblock"><p>The available memory can be further divided into <a class="el" href="zTUIMemPerRes.html#zTUIMemAdd">smaller regions</a> that are later assigned to zones, for example a zone for loader and zone for application.</p>
<p>For memory and peripherals <a class="el" href="zTUIMemPerRes.html#zTUIPerProp">properties</a> such as access permission, privilege, and security level can be configured. These settings can be for example used to generate source code files that configure the device at run-time.</p>
<h1><a class="anchor" id="zTUIMemView"></a>
View memory and peripheral resources</h1>
<p>Initially, this uses the information in the *.rzone file which defines the generic access permissions for memory and peripherals. The CMSIS-Zone Editor shows the <b>Resource</b> <b>Map</b> of the given device:</p>
<div class="image">
<img src="lpc55_resource_map.png" alt="lpc55_resource_map.png"/>
</div>
<p>Here, you can see all resources that are available on the device.You see <b>Memory</b>, <b>Peripherals</b>, <b>Cores</b>, and <b>Info</b> related to the resources. <a class="el" href="zTUI.html#zTGUIZoneEditor">Colored resources</a> are assigned to a zone.</p>
<h1><a class="anchor" id="zTUIMemAdd"></a>
Create Memory Regions</h1>
<p>To create a new memory region, right-click on the memory that you want to divide and select <b>Add memory region</b>:</p>
<div class="image">
<img src="AddMemoryBlock.png" alt="AddMemoryBlock.png"/>
</div>
<p>In the dialog a name derived from the parent memory region is provided. Change this region name as needed and specify the size. In this dialog, you change permissions, privilege, or security level for the memory region. When done, click <b>Finish:</b> </p>
<div class="image">
<img src="NewMemoryBlockWiz.png" alt="NewMemoryBlockWiz.png"/>
</div>
<p>The new memory region is immediately shown in the zone map. Depending on the security level, you may be able to assign this new region only to certain zones. For example, secure memory regions cannot be assigned to a non-secure zone.</p>
<div class="image">
<img src="IRAM1_1Display.png" alt="IRAM1_1Display.png"/>
</div>
<p>The information about the memory regions is stored in the <a class="el" href="xml_partition.html#xml_amemory">/azone/partition/memory element</a> element of the *.azone file.</p>
<h1><a class="anchor" id="zTUIMemDel"></a>
Delete Memory Regions</h1>
<p>To delete a memory region, right-click on the memory region select <b>Delete memory region</b>:</p>
<div class="image">
<img src="DelMemoryRegion.png" alt="DelMemoryRegion.png"/>
</div>
<h1><a class="anchor" id="zTUIPerProp"></a>
Resource Properties</h1>
<p>To change the properties of a resource, such as a peripheral for example, right-click the resource and select <b>Properties:</b> </p>
<div class="image">
<img src="res_prop.png" alt="res_prop.png"/>
</div>
<p>Then, you can set these properties:</p>
<div class="image">
<img src="peripheral_properties.png" alt="peripheral_properties.png"/>
</div>
<p><b>General</b> </p>
<ul>
<li><code>Shared:</code> the resource can be accessed by more than one zone</li>
<li><code>Startup:</code> locate the vector table to this region</li>
<li><code>No</code> zero init: preserve RAM content at startup</li>
<li><code>DMA:</code> enable direct memory access</li>
</ul>
<p><b>Permissions</b> </p>
<ul>
<li><code>peripheral:</code> mark this as a peripheral</li>
<li><code>read</code> </li>
<li><code>write</code> </li>
<li><code>execute</code> </li>

<ul>
<li><code>not</code> specified</li>
<li><code>non-secure</code> </li>
<li><code>non-secure</code> callable</li>

</ul>
<p>The information about the peripherals is stored in the <a class="el" href="xml_partition.html#xml_aperipheral">/azone/partition/peripheral element</a> element of the *.azone file.</p>
<h1><a class="anchor" id="zTUIPerSlotConf"></a>
Configure peripheral slot access rights</h1>
<p>Peripherals can have so called slots that can be configured separately. Depending on the peripheral, the slots have different names in the Zone Editor. For example, for DMA they are called <b>Channels:</b> </p>
<div class="image">
<img src="dma_channel_config.png" alt="dma_channel_config.png"/>
</div>
<p>For GPIOs, they are called <b>Pins:</b> </p>
<div class="image">

</div>
<p>In the dialog, you can set security and privilege levels:</p>

</div>
<p>The information about the slots is stored in the <a class="el" href="xml_partition.html#xml_aslot">/azone/partition/peripheral/slot element</a> element of the *.azone file. </p>

<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>
