4.2.1 JFFS2 File System Configuration
JFFS2 is a log-structured file system designed for use on flash devices in
embedded systems. Rather than using a kind of translation layer on flash devices
to emulate a normal hard drive, as is the case with older flash solutions, it places
the file system directly on the flash chips.
If you want to use JFFS2 file system on Flash Memory then you have to configure
both the Flash Memory driver and JFFS2 file system. First do the Flash Memory
Driver configuration as described above. And then follow the procedure below to
configure the JFFS2 File system.
