Buffalo LinkStation LS421DE is a dual bay NAS, based on Marvell Armada 370
Hardware:
SoC: Marvell 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 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.
