i personally do my backups with "cp"
cp /dev/mtdblock6 /media/card/rootfs
and vice versa.
#blocksave.sh
#!/bin/sh -x
for i in 1 2 3 4 5 6 ; do echo cp /dev/mtdblock$i ${i}_* ; cp
/dev/mtdblock$i ${i}_* ; done
# blockrestore.sh
#!/bin/sh -x
for i in 1 2 3 4 5 6 ; do echo cp ${i}_* /dev/mtdblock$i ; cp ${i}_*
/dev/mtdblock$i ; done
and in practice, this works for backup _and_ restore
but the backup with the assumption, that there are the destination files
already in the directory, like:
-rw-r--r-- 1 root root 262144 Sep 25 09:11 1_uboot
-rw-r--r-- 1 root root 262144 Sep 25 09:11 2_uboot-env
-rw-r--r-- 1 root root 8388608 Sep 25 09:11 3_kernel
-rw-r--r-- 1 root root 655360 Sep 25 09:11 4_splash
-rw-r--r-- 1 root root 262144 Sep 25 09:11 5_factory
-rw-r--r-- 1 root root 258605056 Sep 25 09:16 6_rootfs

On IRC, I asked someone to
dd if=/dev/mtd0 of=nor.img
for me. Does that work? The link in the wiki page is dead.
I always flash my kernel and rootfs from NAND u-boot menu.

To flash something via USB cable with dfu-util you have to be in the
NOR boot menu. But it's totally legal to reflash /dev/mtd1 (u-boot),
mtd2 (u-boot_env) or mtd3 (kernel) when you have booted into the
rootfs in NAND. When you've booted from sd-card, you can reflash mtd6
(rootfs) too. Use flash_eraseall and nand_write for this.
Writing to /dev/mtd0 (NOR boot) is possible without debug board too,
you need need to enable write access to it. See
