OpenWrt 15.05 for Orange LiveBox 2.1 Arcadyan ARV7519RW22

I managed to generate a OpenWrt 15.05 image for Orange LiveBox 2.1 (Arcadyan ARV7519RW22) because the official one gives a kernel panic due to flash partitioning bugs.

This router supports both VDSL & ADSL and is quite powerful. Full specs here:

Details:

• Synced with Chaos Calmer 15.05 Final (LuCI git-15.248.30277-3836b45)
• Includes LuCi & default packages as the standard OpenWrt release.
• Includes VDSL.bin firmware
• added patches to fix:  VFS kernel panic / VLans switch, Led names/colors, secondary usb.
• Enabled FPU Emulation

Here you can download it: (Works for both hardware versions R01 VR9 1.1 and R02 VR9 1.2) 

• Chaos Calmer 15.05 for Orange LiveBox 2.1 Arcadyan ARV7519RW22 image

Note: This image come with VDSL support enabled by default. If you want to use this router with a ADSL line then:

1. Edit this file:    /etc/config/network
2. and look for this line   option xfer_mode 'ptm'     and  change it to     option xfer_mode 'atm'

OpenWrt 15.05 for Yacom Arcadyan ARV4518PW

I managed to generate a OpenWrt 15.05 image for ARV4518PW because the official one gives a kernel panic due to lack of space. The idea here is to get it running while stripping things that can be installed later with Extroot:

I had to do these steps to fit OpenWrt in less than 4 MB of that router total flash memory :

• Synced with Chaos Calmer 15.05 Final (LuCI git-15.248.30277-3836b45)
• Disabled IPv6 support (can be restored by installing IPv6 packages mainly luci-proto-ipv6 + odhcp6c)
• Removed swconfig package (because VLANs support is somehow still buggy. Wiki refs: 1, 2)
• Removed debugging (useless anyway if you're not a developer)
• Optimized compiling for size
• Enabled FPU Emulation
• Included LuCi
• Added : USB2 support + Ext4 Filesystem for Extroot + block-mount

The result is an image that fits well in ARV4518PW with 108 KB of free flash space.

Here you can download it (Pay attention to your router hardware version in its back: either R01A or R01):

• Hardware version: R01A
• For ARV4518PW R01A

or

• Hardware version: R01
• For ARV4518PW R01

Note: if you get a VFS not syncing kernel panic then check your router's MTD partitions size and probably you need to reflash a 64kb u-boot with the propre environment parameters.

Flashing Yacom Arcadyan ARV4518PW with OpenWRT 14.07 / 12.09

Arcadyan ARV4518PW Router also known as SMC-7908-ISP is one of the few routers with Lantiq SoC capable of connecting to the Internet with their integrated xDSL modem.

There are guides and HowTos explaining how to flash this router with OpenWRT. A UART USB-to-TTL cable is a must to flashing.

Here is a recap for all the steps.
1. backup your routers original firmware and wifi calibaration data.
2. flash the bootloader u-boot.
3. from u-boot, we will issue commands to download and install OpenWRT into the flash.


Details:

1. Backup your router's firmware & WiFi calibration data

You will need a Serial Communication software like Putty, CuteCom or Screen installed on Linux.

Then need to get BrnDumper from here. (Works reliably on a 32bits Linux)

Connect your UART cable.

Open Terminal and issue:

screen /dev/ttyUSB0 115200


Power up your router

when text starts showing up on Terminal, hit spacebar 3 times

then hit  !  and quit  screen



now open another Terminal Tab/Window and run brndumper as follow:

sudo ./brndumper --port=/dev/ttyUSB0


and do a full dump and a Wifi calib data dump.
from  $b0000000  to  $b0400000 -> full dump
from  $b03F0000  to  $b0400000 -> wifi calib data dump

it's going to take approx 30mins.

2. flash the bootloader u-boot

when it finishes, power off the router. Start CuteCom or a Serial Comm software capable of sending files using XModem and change its Input Mode to "No Line End".

Power on the router. When the text starts showing up hit spacebar 3 times then hit respectively:

!
U
0 
Y

Then send u-boot file via XModem

When it's done restart the router



3. Installing OpenWRT from u-boot

Install a TFTP Server. Download either of these OpenWRT images, rename it to ARV4518PW-squashfs.image and put it into tftp folder.

• OpenWRT 12.09 for ARV4518 (valid for R01A and R01)
• OpenWRT 14.07 for ARV4518 valid for hardware revision R01A
• OpenWRT 14.07 for ARV4518 valid for hardware revision R01

Note: these images are custom compiled and patched to fix Wifi on 12.09 and let them fit well on the 4MB of flash while having extra drivers (USB2, Ext4, USB Storage) and still have enough free space to do other things.


Connect a network cable to the router, set a static ip like, i.e:

ifconfig eth0 192.168.144.100 netmask 255.255.255.0 up


the ip address 192.168.144.100 came from the output values of  printenv  which you can issue from CuteCom.


From CuteCom issue:

setenv kernel_addr 0xb0020000

saveenv

run update_openwrt

when it finish, issue:

reset


Enjoy.
