Re: [ts-7000] Problem Cloning flash partition

[Drew DeKoning <>]

Are you root?

Maybe check partition on device with "fdisk -l"

Also check path - /dev/???

Hi,
Trying to create image of a onboard flash partition on a ts7260 using dd. I did the following:

1. nfs boot (root filesystem is on a remote machine)
2. dd if=/dev/mtdblock/1 of=/flash.img

I get the following error, does anyone know what's wrong? Thanks.

dd if=/dev/mtdblock/1 of=/home/flash.img
