the Port</title><shortdesc>How to run unit tests of the SDIO platform-specific layer.</shortdesc><prolog><metadata><keywords/></metadata></prolog><taskbody>
<prereq id="GUID-A029444C-0BF1-4D78-88EF-48AFBC35606B">       <p>Before running
this test, you must do the following:<ul>
<li><p>Port the SDIO Controller for your platform (see <xref href="GUID-9BBDFF77-5E2C-4E13-BEB3-716CC80B3375.dita">SDIO
Implementation Overview</xref>)</p></li>
<li><p>Build the test ROM (see <xref href="GUID-2234BCF5-41CC-457A-BF1B-C4AB47931DB8.dita">SDIO
Testing Overview</xref>)</p></li>
<li><p>Boot the device with the test ROM.</p></li>
</ul></p>     </prereq>
<context id="GUID-88D222F5-0078-42E9-B1AF-67C32056EDBE"> <p>The SDIOTest utility
is not an automated test: it performs various unitary operations , which can
be used to validate the behaviour of the SDIO Controller. First, you request
an operation by pressing the corresponding key on the command line. Then,
you compare the resulting display with the data expected from the card. </p><p>The
following steps provide an example of how to test your port.</p>     </context>
