<p><b>Command Syntax:</b></p>
<ul><pre>
mkrd [-m &lt;minor&gt;] [-s &lt;sector-size&gt;] &lt;nsectors&gt;
</pre></ul>
<p>
<b>Synopsis</b>.
Create a ramdisk consisting of <code>&lt;nsectors&gt;</code>, each of size
<code>&lt;sector-size&gt;</code> (or 512 bytes if <code>&lt;sector-size&gt;</code> is not specified.
The ramdisk will be registered as <code>/dev/ram&lt;n&gt;</code> (if <code>&lt;n&gt;</code> is not
specified, mkrd will attempt to register the ramdisk as <code>/dev/ram0</code>.
</p>
<p><b>Example</b></p>
<ul><pre>
nsh&gt; ls /dev
/dev:
console
null
ttyS0
ttyS1
nsh&gt; mkrd 1024
nsh&gt; ls /dev
/dev:
console
null
ram0
ttyS0
ttyS1
nsh&gt;
</pre></ul>
<p>
Once the ramdisk has been created, it may be formatted using
the <code>mkfatfs</code> command and mounted using the <code>mount</code> command.
</p>
<p><b>Example</b></p>
<ul><pre>
nsh&gt; mkrd 1024
nsh&gt; mkfatfs /dev/ram0
nsh&gt; mount -t vfat /dev/ram0 /tmp
nsh&gt; ls /tmp
/tmp:
