Use this to combine components for a project in a certain way, while combining them differently for another project. In the following example, a network stack transfers data via Ethernet. The network stack requires a MAC and PHY to do this. The selected device from silicon vendor A that contains an on-chip MAC, thus only requiring a PHY to be selected:</p> +<div class="image"> +<img src="internal_mac_example.png" alt="internal_mac_example.png"/> +<div class="caption"> +Example with internal MAC</div></div> +<p> You can copy the project, select a different device from silicon vendor B for example and let the run-time environment manager do the exchange of the components. As the new devices do not have an on-chip MAC, you need to select a different component to fulfill the requirement for the network stack:</p> +<div class="image"> +<img src="external_mac_example.png" alt="external_mac_example.png"/> +<div class="caption"> +Example with external MAC and PHY</div></div> +<p> This reduces the development time drastically, as the developer does not need to care for the correct dependency between software components, but can concentrate on the implementation of his own application code.</p> +<h1><a class="anchor" id="cp_PackSteps"></a> +Steps to Create a Pack</h1> +<p>The following image shows the basic steps that are required to create a Software Pack:</p> +<div class="image"> +<img src="PackCreateSteps.png" alt="PackCreateSteps.png"/> +</div> +<ol type="1"> +<li><b>Produce input:</b> Create the files that will be delivered with the Pack.</li> +<li><b>Organize files:</b> Use directories to separate the content of the Pack.</li> +<li><b>Create PDSC file:</b> The XML based PDSC file can be created using any text editor.
