→JFFS2
The Journaled Flash File System v.2 provides non-volatile storing and compression of data on flash devices. For more details about is please see http://www.linux-mtd.infradead.org/doc/jffs2.html. It can be a good choice for not too big flash partitions (as a reference, not bigger than 128 MByte).
Let’s assume we run the kernel by using the [[Booting_Linux_Kernel#Configuration_net_nfs|net_nfs configuration as described ..]]. From the target shell, run
<pre class="board-terminal">
cat /proc/mtd
<pre class="board-terminal">
eraseall /dev/mtd4mtd5
</pre>
<pre class="board-terminal">
mount -t jffs2 /dev/mtdblock4 mtdblock5 /mnt/nand
</pre>
none on /proc type proc (rw)
usbdevfs on /proc/bus/usb type usbdevfs (rw)
/dev/mtdblock4 mtdblock5 on /mnt/nand type jffs2 (rw)
