<section id="triggering-firmware-update">
<h2>Triggering Firmware Update<a class="headerlink" href="#triggering-firmware-update" title="Permalink to this heading"></a></h2>
<p>SBL for ICX-D uses BIOSSCRATCHPAD3_CFG (Bus 0x1E, Dev 0, Func 2, PCI_Config 0xAC) to trigger firmware update. When BIT0 is set, SBL will set the boot mode to FLASH_UPDATE.
Please refer to <a class="reference internal" href="../security/firmware-update.html#firmware-update"><span class="std std-ref">Firmware Update</span></a> on how to trigger firmware update flow.
Below is an example:</p>
<p>To trigger firmware update in SBL shell:</p>
<ol class="arabic">
<li><p>Copy <code class="docutils literal notranslate"><span class="pre">FwuImage.bin</span></code> into root directory on FAT partition of a USB key</p></li>
<li><p>Boot and press any key to enter SBL shell</p></li>
<li><p>Type command <code class="docutils literal notranslate"><span class="pre">fwupdate</span></code> from shell</p>
<p>SBL will reset the platform and initiate firmware update flow. The platform will reset <em>multiple</em> times to complete the update process.</p>
