 130 <div class="textblock"><p><a class="anchor" id="md_src_core_files_in_packs"></a> In simple individual cases the <a class="el" href="cmsis_core_files.html">CMSIS-Core Files</a> can be delivered to developers as part of example projects and SDKs. But the most scalable approach with improved usability is to provide them packaged in <a href="https://www.open-cmsis-pack.org">Open-CMSIS-Pack format</a>, and this page explains how to do this.</p>
 131 <p>The <a class="el" href="cmsis_core_files.html#cmsis_standard_files">CMSIS-Core Standard Files</a> are provided as part of <a href="../General/cmsis_pack.html">CMSIS Software pack</a> under <b>CMSIS</b> class of components and compose there the <b>CORE</b> group.</p>
 132 <p>The <a class="el" href="cmsis_device_files.html">CMSIS-Core Device Files</a> are delivered in <a href="https://open-cmsis-pack.github.io/Open-CMSIS-Pack-Spec/main/html/cp_PackTutorial.html#createPack_DFP">CMSIS Device Family Packs (DFPs)</a> that provide necessary mechanisms for device support in embedded software. The DFPs are typically maintained by device vendors.</p>
 133 <p>Since <a class="el" href="device_h_pg.html">Device Header File &lt;Device.h&gt;</a> does not need to be modified in the project, it can be made accessible with its include path.</p>
 134 <p>For uniform experience, the files <a class="el" href="startup_c_pg.html">Startup File startup_&lt;Device&gt;.c</a> and <a class="el" href="system_c_pg.html">System Configuration Files system_&lt;Device&gt;.c and system_&lt;Device&gt;.h</a> should be provided in the DFP as part of <b>Device</b> class in the <b>Startup</b> group and defined as configuration files, meaning they are copied from the pack into a project folder and can be modifed there if necessary.</p>
 135 <p>Below is an example of how CMSIS-Core device files can be defined in a .pdsc file of DFP pack, based on the implementation for a generic Cortex-M55 device.</p>

 168 <p>Looking at other Device Family Packs can be also helpful to understand the CMSIS-Core support with DFPs. The list of public CMSIS packs (including DFPs) can be found at <a href="https://www.keil.arm.com/packs/">keil.arm.com/packs</a>. </p>
