Hi friends!
I need your help. I was trying to update my u-boot on Iomega / Lenovo ix2 NAS device and accidentally erased the u-boot using the next command:

sf erase all

Please tell me what to do to restore my device?

Gadjie,

To recover from this situation, try booting with UART using kwboot. Here is an example for the NSA320S.

https://forum.doozan.com/read.php?3,51739,51919#msg-51919

Basically, you need to either find the mtd0 backup (where u-boot image is) someone has made for this this box (using dd). This would be the best image to use. You probably can find the stock u-boot image somewhere in the FW upgrade or recovery image from Iomage/Lenovo website.


Or if you cannot find the Iomega IX2 u-boot, then use an u-boot image for another box that is is close to this one.

Your box is similar to the NSA325 in term of the SoC and memory. So try that image.

https://forum.doozan.com/read.php?3,12381

Download uboot.2017.07-tld-1.nsa325.bodhi.tar. And untar it to get uboot.2017.07-tld-1.nsa325.mtd0.kwb

You can use the kwboot binary that comes with the Linux host that you are using to connect serial console.

Hi,
Thank you for your forum and quick response.

I enter the following commands and nothing happens, how long do I have to wait?

sudo kwboot -t -B 115200 /dev/ttyUSB0 -b ./kwboot-tool/u-boot.kwb -p
Sending boot message. Please reboot the target...\

I got this file from the next link
http://ftp.debian.org/debian/dists/stable/main/installer-armel/current/images/kirkwood/u-boot/sheevaplug/u-boot.kwb.



AND

sudo kwboot -t -B 115200 /dev/ttyUSB0 -b ./uboot.2017.07-tld-1.nsa325.mtd0.kwb -p
Sending boot message. Please reboot the target...|

But the commands does not work, I waited 20 minutes and no action.

The forum is hosted by Jeff Doozan, the pioneer who created this forum and provided hacking instruction in the early days that we have been building upon!

Some Kirkwood boxes do not have UART booting capability. I hope that your box does, but try searching the forum (use Advanced search to include all dates) to see if anybody has tried this for the IX2.

The Sheevaplug probably not a good image to use. It has 512MB RAM and is a 6281 SoC. Your box is 6282 and has 256MB RAM.

However, as long as it is a Kirkwood SoC u-boot image, at least it will start and then stops if the mismatch is too important (i.e. such as RAM). And we will get a u-boot banner output to the console.

Also try the T5235 u-boot:

https://forum.doozan.com/read.php?3,26562

uboot.2017.07-tld-1.t5325.mtd0.kwb

The T5325 is 6281 SoC with 512MB RAM, but it has SPI flash like your box.
