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:
Procedure:
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.

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:
Kod:
tftpboot 0x2000000 zImage
tftpboot 0x5400000 initrd
nand erase 0x100000 0x300000
nand erase 0x540000 0x300000
nand write.e 0x2000000 0x100000 0x300000
