I have mounted JFFS2 successfully, according to the return value.
Yes, it takes some time to do the mounting work.
But, when I downloaded a file like "test.txt" into flash via FTP and
restarted the system, error came up.
Unmount the file system before you restart the system.

mount failed.
Everything worked well, after erasing the whole flash. But errors came
up without erasing it.
Make sure your flash driver works correctly. It must support bytewise
programming.
