| <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> |

| Using the CMSIS-Zone project</h1> |
| <ul> |
| <li><a class="el" href="zTExamples.html#zTExImport">Import</a> the project "Examples\SAML11\Zone" into the CMSIS-Zone utility</li> |
| <li><a class="el" href="zTUI.html#zTProjEx">Open</a> the SAML11.azone file</li> |
| <li><a class="el" href="zTUIGenerate.html">Generate</a> the related output files</li> |
| </ul> |
| <p>The SAML11.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>sApp</code> and <code>nsApp</code> </li> |
| <li><a class="el" href="zTUIMemPerRes.html#zTUIMemAdd">Created the memory regions</a> <code>APP_NS</code>, <code>APP_S</code>, <code>APP_NSC</code>, <code>DATA_NS</code>, <code>DATA_S</code>, <code>RAM_NS</code>, and <code>RAM_NS</code> </li> |
| <li>Selected various memory regions and peripherals for using in the different zones: <div class="image"> |
| <img src="SAML11_zones.png" alt="SAML11_zones.png"/> |
| </div> |
| </li> |
| </ul> |
| <p>The zones use different Flash and SRAM regions for code and data. 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> |
| <th align="left">Template File </th><th align="left">Generated File </th><th align="left">Description </th></tr> |

| </table> |
| <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> |

| <li>Navigate to Examples/SAML11/MDK</li> |
| <li>Open the multi-project workspace NoRTOS.uvmpw</li> |
| <li>Run the batch build in MDK. Both projects, sApp and nsApp need to be compiled in order. </li> |
