<h4>Description</h4>
|
||
|
|
<p>The f_mountdrv forces the partition mounted (initializes <tt>FATFS</tt> structure). The file system is initialized automatically in accordance with the necessity when any file function is called. This function should not be used except for recovering <tt>FR_INCORRECT_DISK_CHANGE</tt> error. Using this function, while any file is opened, can destroy the file system.</p>
|
||
|
|
<p>In this function, following processes are executed.</p><br>
|
||
|
|
<ul>
|
||
|
|
<li>Initializes lower level layer (disk I/O module).</li>
|
||
|
|
<li>Searches a FAT boot record in order of sector 0 (as SFD format) and first primary partition (as FDISK format).</li>
|
||
|
|
<li>Initializes file system object (<tt>FATFS</tt> structure).</li>
|
||
|
|
</ul>
