The Buffalo LinkStation LS220DE is a dual bay NAS, based on Marvell
Armada 370
Hardware:
SoC: Marvell Armada 88F6707
CPU: Cortex-A9 800 MHz, 1 core
Flash 1: SPI-NOR 1 MiB (U-Boot)
Flash 2: NAND 512 MiB (OS)
RAM: DDR3 256 MiB
Ethernet: 1x 1GbE
USB: 1x 2.0
SATA: 2x 3Gb/s
LEDs/Input: 5x / 2x (1x button, 1x slide-switch)
Fan: 1x casing
Flash instructions, from hard drive:
1. Get access to the "boot" partition at the hard drive where the stock
firmware is installed. It can be done with acp-commander or by
plugging the hard drive to a computer.
2. Backup the stock uImage:
mv /boot/uImage.buffalo /boot/uImage.buffalo.bak
3. Move and rename the Openwrt initramfs image to the boot partition:
mv openwrt-initramfs-kernel.bin /boot/uImage.buffalo
4. Power on the Linkstation with the hardrive inside. Now Openwrt will
boot, but still not installed.
5. Connect via ssh to OpenWrt:
ssh root at 192.168.1.1
6. Rename boot files inside boot partition
mount -t ext3 /dev/sda1 /mnt
mv /mnt/uImage.buffalo /mnt/uImage.buffalo.openwrt.bak
mv /mnt/initrd.buffalo /mnt/initrd.buffalo.bak
7. Format ubi partitions at the NAND flash ("kernel_ubi" and "ubi"):
ubiformat /dev/mtd0 -y
ubidetach -p /dev/mtd1
ubiformat /dev/mtd1 -y
8. Flash the sysupgrade image:
sysupgrade -n openwrt-squashfs-sysupgrade.bin
9. Wait until it finish, the device will reboot with OpenWrt installed
on the NAND flash.
Restore the stock firmware:
1. Take the hard drive used for the installation and restore boot backup
files to their original names:
mount -t ext3 /dev/sda1 /mnt
mv /mnt/uImage.buffalo.bak /mnt/uImage.buffalo
mv /mnt/initrd.buffalo.bak /mnt/initrd.buffalo
2. Boot from the hard drive and perform a stock firmware update using
the Buffalo utility. The NAND will be restored to the original
state.
