reverse mkfs.jffs2

reverse mkfs.jffs2

[Eric DEJONC]

Hi all,
I was wondering if someone had already done a prog that reverse
mkfs.jffs2?

I'd like to open a jffs2 ramdisk made by someone else, but I don't have
enough space on my flash disk. So I would like to open it, but from the
host machine that doesn't handle  jffs2.

Best regards
Eric

Use one of mtdram or mtdblock and use that. You can make a block
device from your image with loopback. Should be enough, I guess.

Well, thank you, I did not think to loopback, thats a great idea. I'm gonna
test. the only little problem is  that the 10M jffs2 file should take a long
time to be sent on the board via a serial port (the only one I can use).

Berst regards,
Eric

jffs2reader does this, partially.

Well thanks,  I hadn't seen this util, but I'm not lucky, this is the
only one I couldn't compile.
I'm gonna try to compile it.

thanks again

Best regards,
Eric

I don't think you caught on to what mtdram is. mtdram lets you create an
mtdblock device on you *HOST* system. you don't need to send it to your
board via serial.
