<b>Synopsis</b>.
|
||||
Create a ramdisk consisting of <code><nsectors></code>, each of size
|
||||
<code><sector-size></code> (or 512 bytes if <code><sector-size></code> is not specified.
|
||||
The ramdisk will be registered as <code>/dev/ram<n></code> (if <code><n></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> ls /dev
|
||||
/dev:
|
||||
console
|
||||
null
|
||||
ttyS0
|
||||

|

nsh> mkrd 1024
|

nsh> ls /dev

/dev:

ttyS0
|
||||
ttyS1
|
||||
nsh>
|
||||
</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> mkrd 1024
|

nsh> mkfatfs /dev/ram0
