binaries of mtd-utils are inside bootmenu flasher http://fanoush.wz.cz/maemo/initfs_flasher.tgz
For flashable backup you just mount jffs2 system somewhere and create jffs2 image out of it via mkfs.jffs2. Example for rootfs
later you can flash it (when booted from something else than internal flash) via

Thank you very much.
I already did that with rootfs and initfs .
Since nobody seems to have compiled 0xFFFF for the tablet I guess I'll have to do it myself once I put on the build environment. Seems a more appropiate tool to backup (it can dump CAL and Xloader areas too)

I have static binaries of mtd-tools and 0xFFFF (for initfs) here:
http://qwerty12.maemobox.org/initfs
It's static but compiled against uclibc so I dunno if it will work on a booted system.
For dumping CAL, cat /dev/mtd1 > /media/mmc2/mycalfile should do it. edit: seems not, thanks fanoush.

Thanks. I just remembered that I modified the dump function on 0xffff not to ask questions and not to strip :/. (i made it for the purpose for running straight from bootmenu), I'll recompile tomorrow with the original source.

For backup both are good, for restore I wouldn't trust any of them directly on the device for bootloader or CAL area.

Has anyone got debs or already built binaries of mtd-tools and 0xFFFF for the tablet (diablo)?
I'm trying to do a flashable backup, but can't find the tools in any repo.
