Bays 4
Network 1x 10/100/1000 Mbps (Marvell 88E1518)
Sata 4x SATA via 4-port multiplier (Marvell 88SM4140)
NAND Flash 512MB **LS-QVL/E Only
SPI Flash 512KB
USB 2.0 1x Front, 1x Rear via USB Hub (USB2512B)
USB 3.0 None
Fan Yes
Power 19V - 4.74A

Stock Firmware Installation

  • For the LS-QVL/E There is a simple procedure to lead the firmware from the device's NAND, this procedure can be found in Buffalo's "Quick Setup Guide for LS-QVL/E" which can be found here
  • Restoring_Stock_Firmware_without_TFTP

Custom Firmware/Operating System installation

These devices are supported by Debian and can be setup using the Debian network-console installer, see Installing_Debian_on_Supported_Devices

Serial Console

The Rx and Tx lines can be accessed next to the SoC where they connect to their pull-up resistors R99 and R150. U-boot appears to check GPIO 49 to decide whether to interact with the serial console. To re-enable it you can move the 4.7k resistor pulling it high on R60 to R59. It might be more correct to use a 1k resistor instead, I just removed R60 and bridged R59 which works but probably risks damage to the board.

The traces between the SoC and the serial header on the board are disconnected underneath the SPI chip on the back, I haven't pulled the chip to confirm but I would bet there are pads underneath. Both sides are also accessible underneath where the spot for the NAND chip goes which is easier to access for the non-NAND devices.
