JFFS2 - file system size question


Hi,

I'm preparing JFFS2 file system with the command:
mkfs.jffs2 -n -r 'my folder' -e 64 -o jffs2.bin
I have 1 file in 'my folder'. Created jffs2.bin has ~60kB.
Then I write jffs2.bin into my /dev/mtd5.
My /dev/mtd5 area is 14 MB.

How does it work afterwards.
- will JFFS2 automatically use the rest of the /dev/mtd5 when I copy new files into it?
- Can I create jffs2.bin from empty folder ? Is JFFS2 going to use all available space in /dev/mtd5 ?

Than you for any hints.

BR

You create a file system on MTD5 partition. So it will use all space on the partition. If you want less, create a smaller partition.
