Buffalo LinkStation LS421DE is a dual bay NAS, based on Marvell Armada 370
Hardware:
SoC: Marvell Armada-370 88F6707-A1
CPU: Cortex-A9 1200 MHz, 1 core
Flash: SPI-NOR 1 MiB, NAND 512 MiB
RAM: DDR3 512 MiB
Ethernet: 1x 10/100/1000 Mbps
USB: 1x 2.0, 1x 3.0
SATA: 2x 3.0 Gbps
LEDs/Input : 5x / 2x (1x button, 1x slide-switch)
RTC: Ricoh RS5C372A, I2C, no battery
Flash instruction (UART+TFTP):
1. Downgrade the OEM firmware to 1.34 (BUFFALO_BOOTVER=0.13)
2. Boot the Openwrt initramfs image using the U-Boot serial console:
tftpboot buffalo_ls421de-initramfs-kernel.bin;bootm
3. Flash the sysupgrade image using the Openwrt console:
sysupgrade -n buffalo_ls421de-squashfs-sysupgrade.bin
5. Wait until it finish, the device will reboot with Openwrt installed
on the NAND flash.
Note:
- Device shuting down doesn't work, even if the power slide switch is
used. We must first, via MDIO, set the unused LED2 at the ethernet
phy0 to off state. Reboot works ok.

Changes in v2
- Tune the dts file
- Adjust the i2c bus speed to the max supported by the RTC
- Delete unneded kernel patch
- Image creation: only include neccesary packages, delete the ubinize
parameter
