Recovering IOmega ix2-200 after failed upgrade

The following was my solution to fix a bad NAND flash, after an upgrade failed halfway through. Your mielage may vary, but you could at least give it a try.

You’ll get access to the bootloader, and be able to upload a new image via TFTP …
You’ll need:

• RS232 to TLL level shifter 3.3V (I used a PL2303 based clone from Ebay costing about $5,- incl. shipping)
• Philips #2 screwdriver, hobby knife
• Computer with TFTP server installed, configured at 192.168.1.100
• Decrypted firmware for the unit – see this page for instructions.
• Prepare a FAT32 formatted USB key with the upgrade file placed in /emctools/ix2-200d_images/ix2-boot.tgz
• Place zImage and initrd (from the ix2-boot.tgz file) on your TFTP server.

Procedure:

• Connect the USB key to any port on your ix2
• Connect your TTL level shifter to JP1 – see this page for pinout.
• Connect your ethernet cable from the ix2 to your computer.

At the Marvell>> prompt, do the following:


That will load the kernel and initrd into memory, and write them to the NAND of the ix2. Now you can either powercycle the unit, or just issue


As I had totally cleaned drives in my unit, the upgrade/wipe happened automatically, just wait 5-10 minutes. Also you can connect to your DHCP enabled network and access the unit (when the procedure completes).
Also you can take a look at Nigels page here, if you want to tinker more and install a full Debian on the unit.

All,

I'm holding a ix2-200 as well.
I have followed the above instruction to install zImage and initrd on the ix2-200.

when I boot the ix2-200 with the USB in the lower USB slot end hold the re-set button i'm able to see that the OS sees the Image tar file.
but gives a error.

see capture of the data that I retrieved ussing PuTTY.

Does one of you has a sulotion for this?
I have tried 4 USB stickes variouse brands and sizes.
I have also tried variouse tgz files all give the same error.

Is thay a way to install the decrypted files rerectly to the ix2-200 / harddisk by ussing PuTTY and TFTP server?

thanks
