Hi All,
First, the words of warning. I've only been looking at this for the past
couple of days so don't count me as an expert.
However, et me venture a guess.
Are you sure the SD card is in /dev/sdb?
I've been looking at a 8390-4800 setup and the card is at /dev/mmcblk0
the manual says you should unmount before restoring.
Just to check:
# mount
rootfs on / type rootfs (rw)
/dev/root on / type ext2 (rw,relatime,errors=continue)
none on /proc type proc (rw,relatime)
none on /sys type sysfs (rw,relatime)
none on /dev type tmpfs (rw,relatime)
/dev/mmcblk0p4 on /mnt/root type ext3
(ro,relatime,errors=continue,barrier=0,data=writeback)
none on /dev/pts type devpts (rw,relatime,mode=600)
none on /dev/shm type tmpfs (rw,relatime)
tmpfs on /tmp type tmpfs (rw,relatime)
This shows partition 4 of the SD card mounted at /mnt/root
so your dd command should then contain of=/dev/mmcblk0 as opposed to
/dev/sdb.
I put a fresh image on my SD card without incident but the manual says
it should be unmounted first. 'umount /mnt root' complains the
filesystem is in use.
I suspect I have to change over from the fastboot to something else that
won't mount the SD card, but I haven't gotten there yet.
Hope this helps,
Steve
