Opening the case

Note: This will void your warranty!

To get to the board you need:

  • unscrew 2 Phillips screws underneath the cover,
  • pull the upper cover which is connected by click.


Name Colour Gpio
Power red 7
Power green 2
Wifi green 6
Adsl green 4
Internet green 5
Internet red 8
Voip green 100
Phone 1 green 101
Phone 2 green 102
Noname Orange 103
USB green 19
wps Orange 104
wps Green 105
wps Red 106



Board voltage is 3.3V so can use usb to serial adapters.

Bootstrap settings

Bootstrap pin funcion table:

X = boot_sel2 Y = boot_sel1 Z = boot_sel0 X Y Z function =============================================================== 0 0 0 External parallel flash 0 0 1 ROM > external parallel flash (default) 0 1 0 ROM > ethernet, MII0 0 1 1 ROM > PCI 1 0 0 ROM > UART1 1 0 1 ROM > serial SPI 1 1 0 ROM > NAND flash 1 1 1 ROM > Reverse MII0

Value 1 = 3.3v is connected to that pin
Value 0 = Pin is connected to digital GND

boot_sel2, boot_sel0 pins location:

Note: boot_sel2 and boot_sel1 are by default on 0 and boot_sel0 is on 1.


To enable uart mode, short pins at boot_sel2 (see picture) and connect boot_sel0 to 3.3V(serial port vcc). Than you can send u-boot.asc(downlaod here) to serial port.
For example if your serial port is ttyUSB0 than do: "cat u-boot.asc > /dev/ttyUSB0" and wait until u-boot starts.

UART mode looks like this:

ROM VER: 1.0.3
CFG 04

Step by step via serial connector

Please read the following links for ARV4518. They will give you another point of view of the process:

And buy the usb to ttl conversor suggested by pippolippi or build one yourself:


  1. (about 2h) Backup your router twice and compare the results to ensure you have a correct backup. Use brntool from Command: "./ –serial=/dev/ttyUSB0 –read=AR4518PW_whole2.dump –addr=0xB0000000 –verbose –size=0x800000"
  2. download uboot for arv4518 (the one for 7518 has bug in its last versions, does not work for http/tftp and has no loady support) from (If you need to enable UART for recovery purposes, not now, the asc file is in )
  3. I use cutecom, a gui for serial console. First step is to tell it that the device is /dev/ttyUSB0 and set "No Line End"
    1. Speed: 115200 baud
    2. Data bits: 8
    3. Stop bits: 1
    4. Parity: None
    5. Flow control: None
  4. Next step is very well explained in step 8 in Follow it step by step using file "" you downloaded before.
  5. Step 9 in is not completely valid because tftp/http does not work, so you cannot use "run update_openwrt". The correct steps instead of that one are shown in, but first you have to download an image. In there is no image for arv7518 today(31/10/2012) but there is one in, Download it. Now do:
    1. request to upload via YModem: "ARV4518 ⇒ loady 0x80500000"
    2. choose in cutecom "YModem", press "Send file…" and choose the file you've download. It takes about 10 mins. The steps after uploading are:

ARV4518 => era ${kernel_addr} +${filesize}

............................................. done
Erased 45 sectors
ARV4518 => cp.b ${ram_addr} ${kernel_addr} ${filesize}
Copy to Flash... 9....8....7....6....5....4....3....2....1....done
ARV4518 => 

now reboot and let it load. You have a log of the full loading process in OpenWRT is installed. Time to configure it.
