Buffalo LinkStation LS421DE

This is a low-cost dual-port SATA NAS box. It comes with one 1GbE network port, one USB 2.0 host port on the back and one USB 3.0 on the front.

Stuff used in the installation:

The box must have at least 1 hard drive installed in a bay. First check that the stock firmware is working ok. 192.168.1.11 is the IP of the device, 192.168.1.7 is the IP of our computer.

  1. Downgrade the firmware to 1.34 version (BUFFALO_BOOTVER=0.13)
  2. Use acp_commander to enable a root shell over telnet:
    java -jar acp_commander.jar -t 192.168.1.11 -pw password -o
  3. Open a telnet session on the device:
    telnet 192.168.1.11
  4. Backup the stock uImage:
     mv /boot/uImage.buffalo /boot/uImage.buffalo.bak
  5. Download the Openwrt initramfs image and reboot:
    wget -O /boot/uImage.buffalo http://192.168.1.7:8000/openwrt-mvebu-cortexa9-buffalo_ls421de-initramfs-kernel.bin
    sync
    reboot
  6. Now the device will load the Openwrt RAM image (not installed yet). Open a secure shell into Openwrt:
    ssh root@192.168.1.1
  7. Optional: restore the stock uImage:
    mount -t ext3 /dev/sda1 /mnt && mv /mnt/uImage.buffalo.bak /mnt/uImage.buffalo

    This will make easier to restore the stock firmware after installing OpenWrt.

  8. Download the sysupgrade image, and install it:
    cd /tmp
    wget http://192.168.1.7:8000/openwrt-mvebu-cortexa9-buffalo_ls421de-squashfs-sysupgrade.bin
    sysupgrade -n openwrt-mvebu-cortexa9-buffalo_ls421de-squashfs-sysupgrade.bin
  9. Wait until it finish.
  10. Power off the device
  11. Remove the hard drive or you might end up booting the initram. Keep it apart if you want back to the stock firmware later.
  12. Power on the device. It will boot with openwrt installed in the NAND flash

Note: If you want to start using external storage see NAS configuration

  • ipaddr: 192.168.11.150
  • serverip: 192.168.11.1
  1. Downgrade the OEM firmware to 1.34 (BUFFALO_BOOTVER=0.13)
  2. Remove any hard drive inside the bays. Keep it apart if you want to go back to stock firmware later.
  3. Boot the Openwrt initramfs image using the U-Boot serial console:
    tftpboot 0x1200000 openwrt-mvebu-cortexa9-buffalo_ls421de-initramfs-kernel.bin
    bootm 0x1200000
  4. Flash the sysupgrade image using the Openwrt console:
    sysupgrade -n openwrt-mvebu-cortexa9-buffalo_ls421de-squashfs-sysupgrade.bin
  5. Wait until it finish, the device will reboot with Openwrt installed on the NAND flash.

Post Installation

If you want to start using external storage insert a formatted hard drive inside the bay. The first partition should be never be in EXT4 filesystem format or it will hang at startup otherwise.

Tested partitioning configurations:

  • OK: GPT, 1 partition
    • 1st: XFS, whole hard drive, storage partition
  • OK: GPT, 2 partitions:
    • 1st: EXT3, 8MB, dummy partition
    • 2nd: EXT4, all remaining space, storage partition
  • OK: GPT, 2 partitions:
    • 1st: SWAP, 1GB, virtual system memory.
    • 2nd: EXT4, all remaining space, storage partition
  • OK: GPT, 2 partitions:
    • 1st: SWAP, 1GB, virtual system memory.
    • 2nd: XFS, all remaining space, storage partition
  • FAIL: GPT, 1 partition
    • 1st: EXT4, whole hard drive, storage partition

Remove kernel netfilters

Since this device is presumably used only for attached storage purposes, you can rid of firewall/routing stuff. Remove the firewall related kernel modules:

mkdir /etc/bak
mv /etc/modules.d/nf-* /etc/bak/
mv /etc/modules.d/nft-* /etc/bak/
mv /etc/modules.d/nfnetlink /etc/bak/
mv /etc/modules.d/ipt-* /etc/bak/
mv /etc/modules.d/*ip6tables* /etc/bak/
reboot

After rebooting, the network throughput should be about +15% better.

Cypher Engine

See → Cryptographic Hardware Accelerators

This device has a cypher engine called CESA. It can be used for libraries like openssl.

First install the openssl-util:

opkg update
opkg install openssl-util 

Make a test:

root@LinkStation:~# time openssl speed -evp aes-256-cbc -elapsed You have chosen to measure elapsed time instead of user CPU time. Doing aes-256-cbc for 3s on 16 size blocks: 2580520 aes-256-cbc's in 3.00s Doing aes-256-cbc for 3s on 64 size blocks: 787211 aes-256-cbc's in 3.00s Doing aes-256-cbc for 3s on 256 size blocks: 208627 aes-256-cbc's in 3.00s Doing aes-256-cbc for 3s on 1024 size blocks: 52926 aes-256-cbc's in 3.00s Doing aes-256-cbc for 3s on 8192 size blocks: 6647 aes-256-cbc's in 3.00s Doing aes-256-cbc for 3s on 16384 size blocks: 3327 aes-256-cbc's in 3.00s OpenSSL 1.1.1j 16 Feb 2021 built on: Fri Mar 26 09:12:12 2021 UTC options:bn(64,32) rc4(char) des(long) aes(partial) blowfish(ptr) compiler: arm-openwrt-linux-muslgnueabi-gcc -fPIC -pthread -Wa,--noexecstack -Wall -O3 -Os -pipe -mthumb -fno-caller-saves -fno-plt -fhonour-copts -Wno-error=unused-but-set-variable -Wno-error=unused-result -mfloat-abi=hard -Wformat -Werror=format-security -fstack-protector -D_FORTIFY_SOURCE=1 -Wl,-z,now -Wl,-z,relro -DPIC -fpic -ffunction-sections -fdata-sections -znow -zrelro -DOPENSSL_USE_NODELETE -DOPENSSL_PIC -DOPENSSL_CPUID_OBJ -DOPENSSL_BN_ASM_MONT -DOPENSSL_BN_ASM_GF2m -DSHA1_ASM -DSHA256_ASM -DSHA512_ASM -DKECCAK1600_ASM -DAES_ASM -DBSAES_ASM -DGHASH_ASM -DECP_NISTZ256_ASM -DPOLY1305_ASM -DNDEBUG -DOPENSSL_PREFER_CHACHA_OVER_GCM -DOPENSSL_SMALL_FOOTPRINT The 'numbers' are in 1000s of bytes per second processed. type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 16384 bytes aes-256-cbc 13762.77k 16793.83k 17802.84k 18065.41k 18150.74k 18169.86k real 0m 18.02s user 0m 17.82s sys 0m 0.04s root@LinkStation:~#


Now install the cryptodev module to make the engine available, also install the openssl library:

opkg update
opkg install kmod-cryptodev
opkg install libopenssl-devcrypto 

Open the /etc/ssl/openssl.cnf configuration file and uncomment these lines:

[engines]
devcrypto=devcrypto
 
[devcrypto] 
CIPHERS=DES-CBC, DES-EDE3-CBC, AES-128-CBC, AES-192-CBC, AES-256-CBC

Now make another test:

Custom build

You can also optimize your firmware making your own custom build:

  • Compile the kernel for single core (no SMP stuff).
  • Compile the kernel in THUMB2 mode, and also the user space apps.
  • Patch the kernel to enable the hardware I/O coherency.

The unit has 2 temperature sensors for CPU and ethernet phy, and a FAN cooling. Sensors at hard drives are also available if installed. We can monitor/control them at:

  • /sys/class/hwmon: to check temperatures and FAN. Eg:
    root@LinkStation:~# for i in 0 1 2 3;do cat /sys/class/hwmon/hwmon$i/name;cat /sys/class/hwmon/hwmon$i/*_input;echo;done
    d0072004mdiomii00
    57000
     
    d0018300.thermal
    64593
     
    drivetemp
    36000
     
    gpio_fan
    1500

    The temperature is in millicelsius and the FAN in rpm

  • /sys/class/thermal: to check and modify some parameters.
    CONFIG_THERMAL_WRITABLE_TRIPS kernel option needs to be set to allow modifying thermal trips.

If for some reason the bootloader is broken (no apparent life from the board), you can recover the device by using the UART serial port.

  1. Connect the Linkstation's serial port to your computer
  2. At the computer execute:
    ./kwboot -b uboot.uart -t -B 115200 /dev/ttyUSB0
  3. Power on the Linkstation, wait for it to load.
  4. At the Uboot console execute:
    bubt spiflash_134.bak

Example of recovery session:

./kwboot -b uboot.uart -t -B 115200 /dev/ttyUSB0 Sending boot message.

port.serial general information about the serial port, serial port cable, etc.

The only known way to access the serial console is by wiring up R265 (RX) and R106 (TX) close to the marked edge of the SoC.

There are also two pin headers for the serial port, J11 and J12, but R267 and R268 resistors are missing and the tracings lose continuity under the SPI flash chip:

port.jtag general information about the JTAG port, JTAG cable, etc.

Located at CON2 pads, unknown pinout:

Some boards experience random problems with the ethernet port. This bug is likely caused by an misconfigured voltage on the ethernet pins at the SoC.

  • SoC: as default the RGMII pins are configured to operate at 3.3V
  • PHY: the Marvel 88E1518 can only operate at 1.8V

It turns out that the SoC can be configured via internal registers to set the correct voltage on the RGMII pins. The fix works ok with bootloader from 1.34 firmware version (BUFFALO_BOOTVER=0.13). Most recent firmwares come with a different bootloader and probably using a different initialization for ethernet.

There are three ways to fix this bug:

  1. Setting the registers from userspace: it can be done using devmem. But it requires building a custom firmware with /dev/mem enabled in the kernel, and the utility devmem in busybox:
    devmem 0xd00184e0 32 0xa8a
  2. Patching the bootloader: Flashing a new bootloader might brick your device. This is the patched bootloader (BUFFALO_BOOTVER=0.13) from the firmware version 1.34. It's almost the same stock bootloader but with the fix made after the RAM initialization:

    uBoot with the voltage fix: u-boot.buffalo-1.34_voodoo.tar.gz

  3. Patching the kernel: this seems to be the best option. It won't require user intervention once Openwrt is installed. There is a patch already made for the kernel v5.4.41. But it wouldn't be accepted upstream. See: https://forum.openwrt.org/t/mvneta-help-with-a-voltage-patch/64226

Another workaround that can be made is to wire up the U29 IC (TPS3808) manual reset (pin 4) to a free GPIO. This way we can reset via software the ethernet chip everytime it fails:

ls421de-gpio_ethernet_reset.jpg

  • In the picture we soldered a very thin wire from the GPIO53 to the U29 reset pin. Let's initialize the GPIO53 as output in high state:
    echo 53 > /sys/class/gpio/export
    echo high > /sys/class/gpio/gpio53/direction
  • When the ethernet hangs, we can perform a reset:
    echo 0 > /sys/class/gpio/gpio53/value && sleep 1
    echo 1 > /sys/class/gpio/gpio53/value

Energy-Efficient Ethernet

The ethernet phy is EEE capable. Enabling this feature (using ethtool) may save some miliwatts. Example:

# ethtool --set-eee eth0 eee on

Check if it has been enabled:

# ethtool --show-eee eth0
EEE Settings for eth0:
        EEE status: active
        Tx LPI: disabled
        Supported EEE link modes:  100baseT/Full 
                                   1000baseT/Full 
        Advertised EEE link modes:  Not reported
        Link partner advertised EEE link modes:  100baseT/Full 
                                                 1000baseT/Full 

Note: you may need this kernel patch → https://github.com/torvalds/linux/commit/65a9dedc11d615d8f104a48d38b4fa226967b4ed

Ethernet LEDs

Only one LED pin at the IC is wired to a physical LED.

  • LED0 pin is connected to a physical LED, and used to indicate ethernet link/activity.
  • LED1 pin seems to be wired somewhere but has no known use, or maybe for PTP/802.1AS?
  • LED2 pin is used for poweroff function and Wake On LAN

The Power off function is supported since r14282. The driver also brings the WoL feature which wasn't available in the stock firmware.

To use the WoL feature:

  1. Install the ethtool package in the LinkStation.
    opkg update
    opkg install ethtool
  2. Execute the command:
    ethtool -s eth0 wol g
  3. Power off the LinkStation via command line:
    exec /sbin/poweroff
  4. Wake up from another machine using the LinkStation MAC address (i.e using the etherwake utility).
    etherwake 10:6F:3F:00:00:00

The old way to control the power off function was made by toggling manually the LED2/INTn ethernet PHY pin output before powering off:
Page 3, Register 16, bits 8-11:

  • 0x800 = Force Off
  • 0x900 = Force On

Example in user space, using the utility phytool:

  • LED2 off:
    phytool write eth0/0/22 3; phytool write eth0/0/16 0x1891
  • LED2 on:
    phytool write eth0/0/22 3; phytool write eth0/0/16 0x1991

Phytool openwrt package (patch): http://patchwork.ozlabs.org/patch/1116514/


The board comes with a Ricoh RS5C372A RTC connected via I2C. There is no battery backup, therefore if the power supply is disconnected, the current date and alarms are lost.

We can set the date manually (if the ntpd already didn't):

date -s '2020-11-22 12:34:56'
hwclock -w

Another feature is the RTC alarm. It can be used to wakeup the Linkstation from the power off state at a programmed date.

  • Example of use, wake up 5 minutes after scheduling the alarm:
    echo 0 > /sys/class/rtc/rtc0/wakealarm
    echo $(expr $(date '+%s') + 60 * 5) > /sys/class/rtc/rtc0/wakealarm
    poweroff

    The Linkstation is powered off an it'll come to life after 5 minutes.

  • Wake up at a determined date:
    echo 0 > /sys/class/rtc/rtc0/wakealarm
    echo $(date +%s -d '2020-12-22 8:40:00') > /sys/class/rtc/rtc0/wakealarm
    poweroff

The limit of the alarm is 1 week in the future. But as default it repeats the scheduled days every week.

This alarm works only if these patches were commited:

  • Coherency fabric: it is disabled intentionally in the kernel. This might cause a performance loss. An attempt to reenable the coherence fabric: write-allocate cache policy is required, we also need to disable smp checks for the related stuff.

    After re-compiling the kernel without netfilter modules and testing, the network throughput is about 20% better.

  • Suspend: CONFIG_SUSPEND isn't enabled by default in the OpenWrt kernel. After enabling it in a custom firmware, we can call the suspend command:
    echo -n s2idle > /sys/power/mem_sleep
    echo -n mem > /sys/power/state

    But the machine isn't able to remain suspended, it reboots after the suspend sequence.
