Does JFFS respect partitions?
First, let me say thank you for JFFS!
I am trying to get JFFS to run on one of 2 partitions on a DOC2000.
I ran fdisk on /dev/nftl/disc0/disc (in devfs-parlance; equivalant to
/dev/nftla I think; it's major 93 minor 0). Using fdisk I was able to
create 2 partitions, /dev/nftl/disc/part, and successfully created
an ext2 partition in part3. Now, I want to use JFFS on part4. But,
it seems that JFFS only wants to talk to the raw block device
(/dev/mtdblock/0), not the partitioned block device.
I need to do this because I need one bootable readonly partition (ext2
works fine, I'll probably use cramfs eventually if the bootloader
supports it). The 2nd partition needs to be writable, and therefore
wear-levelled, so I want to use JFFS. But JFFS doesn't want to play
The design of the system demands 2 partitions: one of which is
guaranteed to never be corrupted (the readonly partition), and a
writable but disposable partition, so unfortunately using JFFS for the
entire block device is not an option. (in any case, I don't think you
can boot from a JFFS partition yet.)
Will there be any ill effects if I just remove the check in JFFS for
Also, what's jffs2? Is it safe to use that, and how is it different?
Thanks in advance,
