<div class="textblock"><p><b>Flash Programming Algorithms</b> are a piece of software to erase or download applications to Flash devices. A <a class="el" href="createPack_DFP.html">Pack with Device Support</a> usually contains predefined Flash algorithms for programming the devices that are supported by the DFP. A template for creating new algorithms are available in the <b>ARM:CMSIS</b> Pack. The following section describes the process in more detail.</p>
<h1><a class="anchor" id="CreateFPA"></a>
Creating a new Algorithm</h1>
<p>Flash programming algorithms are defined with functions to erase and program the Flash device. Special compiler and linker settings are required. Follow these steps to create and configure a new Flash programming algorithm:</p>
<ol type="1">
<li>Copy the content from the <b>ARM:CMSIS</b> Pack folder (usually C:\Keil\ARM\Pack\ARM\CMSIS\<em>version</em>\Device\_Template_Flash) to a new folder.</li>
<li>Rename the project file <b>NewDevice.uvprojx</b> to represent the new Flash ROM device name, for example <b>MyDevice.uvprojx</b>.</li>
<li>Open the project with uVision. From the toolbar, use the drop-down <b>Select Target</b> to define the processor architecture. <b>Cortex-M</b> fits for all Cortex-M0/M0+, M3, and M4 devices. The configuration assumes a little-endian microcontroller. In case of a big-endian microcontroller, select the correct processor core with <b>Project</b> - <b>Options for Target</b> - <b>Device</b>.</li>
<li>Open the dialog <b>Project</b> - <b>Options for Target</b> - <b>Output</b> and change the content of the field <b>Name of Executable</b> to represent the device, for example <b>MyDevice</b>.</li>
<li>Adapt the programming algorithms in the file <a class="el" href="flashAlgorithm.html#FlashPrg">FlashPrg</a>.</li>
<li>Adapt the device parameters in the file <a class="el" href="flashAlgorithm.html#FlashDev">FlashDev</a>.</li>
<li>Use <b>Project</b> - <b>Build Target</b> to generate the new Flash programming algorithm. The output file (for example <b>MyDevice.FLM</b>) has to be <a class="el" href="flashAlgorithm.html#AddFPA">added</a> to the <b>DFP</b>.</li>
</ol>
<dl class="section note"><dt>Note</dt><dd><ul>
<li>Creating a Flash programming algorithm with <a href="http://www.keil.com/arm/selector.asp" class="el" target="_blank">MDK-Lite</a> is not supported.</li>
<li>Flash programming algorithms use <b>Read-Only Position Independent</b> and <b>Read-Write Position Independent</b> program code. These options are set in the dialogs <b>Project</b> - <b>Options for Target</b> - <b>C/C++</b> and <b>Project</b> - <b>Options for Target</b> - <b>Asm</b>.</li>
<li>The dialog <b>Project</b> - <b>Options for Target</b> - <b>Linker</b> defines the linker scatter file <b>Target.lin</b>. The error L6305 is disabled with <code>&ndash;diag_suppress</code> <code>L6305</code>.</li>
<li>The <a class="el" href="algorithmFunc.html">Flash Algorithm Functions</a> section contains reference for all the available functions.</li>
</ul>
</dd></dl>
<p><a class="anchor" id="FlashPrg"></a></p>
<h2>FlashPrg.c </h2>
<p>The file <b>FlashPrg.c</b> contains the mandatory Flash programming functions <a class="el" href="algorithmFunc.html#Init">Init</a>, <a class="el" href="algorithmFunc.html#UnInit">UnInit</a>, <a class="el" href="algorithmFunc.html#EraseSector">EraseSector</a>, and <a class="el" href="algorithmFunc.html#ProgramPage">ProgramPage</a>. Optionally, depending on the device features (or to speed-up execution), the functions <a class="el" href="algorithmFunc.html#EraseChip">EraseChip</a>, <a class="el" href="algorithmFunc.html#BlankCheck">BlankCheck</a>, and <a class="el" href="algorithmFunc.html#Verify">Verify</a> can be implemented.</p>
