First mount the image and the partition mmcblk0p4 to a directory:

Code:

mount -o loop /home/user/MyDocs/ed-squeeze-final.ext3 /media/ed

mkdir /mnt/debian-tmp
mount /dev/mmcblk0p4 /mnt/debian-tmp

Then your copy command should look like this:


With your command above, you copy from (empty?) mmcblk0p4 to the mounted ed-image.
----> the general principle is alwas: cp <-opt> <source> <destination>
You can also copy/backup directly from partition (mmcblkXpY) to image file and verse visa with dd.

Example:

Code:

dd if=/dev/mmcblk0p4 of=/home/user/MyDocs/part0p4.ext3

Code:

dd if=/home/user/MyDocs/part0p4.ext3 of=/dev/mmvblk0p4
