Pirelli Alice Gate VoIP 2 Plus Wi-Fi Business

This page is about the above mentioned device also know as agpf.

Supported, but without ADSL.

There are several models of Alice Gate out there, that are not supported at the moment.

Serial

The serial port is J10, on the left of the switch chip, see

6 GND RX 5
4 GND Vcc (3.3V) 3
2 GND TX 1

Settings are 115200 8N1

NB: a short circuit between pins RX and TX at power up puts the device in a recovery mode with IP 192.168.1.1 from where a new firmware can be uploaded. OpenWrt binaries are refused, though, because of invalid CRC.

JTAG

Jtag port is J9 near the SoC and the minipci socket, see

It seems to be a mips e-jtag 14 pin connector with columns swapped (used from the other side?).

14 DINT VREF 13
12 SRST_N GND 11
10 TCK GND 9
8 TMS GND 7
6 TDO GND 5
4 TDI GND 3
2 TRST_N GND 1

CPU Chip ID: 00000110001101011000000101111111 (0635817F)

I used the JTAG port with urjtag, just use the svn version. Useful info on "Neuf Box 4 JTAG"

You should probably try the Open On-Chip Debugger

I don't understand the MaxSize value of some sections as they leave some space before the next section.

Note, when you flash from jtag the BASE ADDRESS is 0x1E000000

OpenWrt on the machine :-)

You will need a serial adpater!!

Don't even try to go further without a serial adapter!!

Backup of the original firmware

Connect the serial adapter and let the device complete the boot procedure. At the login prompt use admin as username and password to get to the openrg Discus prompt.

From the Discus prompt you can do a lot of useful things, but i've not explored it due to some lack of interest. To obtain the shell just digit system shell.

Password: *****

Discus> system shell


BusyBox v1.01 (2005.09.07-07:38+0000) Built-in shell (lash)
Enter 'help' for a list of built-in commands.

/ #

Insert an USB flash key into the usb port of the router and mount the new device somewhere, for example in /mnt/backup

/ # cd mnt/
/mnt # mkdir backup
/mnt # mount /dev/sda
/mnt # mount /dev/sda1 backup/
[   90.535] VFS: Can't find ext3 filesystem on dev sda1.
[   90.590] VFS: Can't find an ext2 filesystem on dev sda1.
[   90.655] cramfs: wrong magic
/mnt #

Now just copy the content of the flash in some files on the usb key.

/mnt # ls /dev/mtd*
/dev/mtd0         /dev/mtd_rgconf0  /dev/mtdblock2    /dev/mtdr2
/dev/mtd1         /dev/mtd_rgconf1  /dev/mtdblock3    /dev/mtdr3
/dev/mtd2         /dev/mtdblock0    /dev/mtdr0
/dev/mtd3         /dev/mtdblock1    /dev/mtdr1
/mnt # dd if=/dev/mtdblock0 of=/mnt/backup/mtdblock
32768+0 records in
32768+0 records out

This will create a 16M file named MTDBLOCK (due to fat limitation). If you prefer you can use an ext2 or ext3 formatted filesystem.

From this file you can extract all you need to do a full restore of your device, both via jtag or via CFE.

Now unmount your flash key, put the file in a safe place and reboot the Alice stopping the boot process at the bootloader prompt pressing some keys.

/mnt # sync
/mnt # umount backup/
/mnt # exit

Going to reboot!

Restore original firmware

FIXME

Installing OpenWrt

You need to setup a tftp server on some host (I can suggest to use dnsmasq for this) to serve the firmware image to the router.

Now just download the image for AGV2+W from http://downloads.openwrt.org/snapshots/trunk/brcm63xx, skip the jffs2 with 64k erase block as the flash use 128k block, anyway using 64k should not give much problem, just some wasted space and some errors messages. Put the choose image in the right place (see your tftp server configuration), and go to the CFE prompt.

Now you have to use the flashimage command to load the openwrt image, please don't use the f command. If you configure (with command c) the host ip address you can avoid it in the flashimage argument.

CFE> flashimage

     eg. flashimage [hostip:]compressed_image_file_name

That's all, the device will automaticly reboot and openwrt will be there :-)

Using dnsmasq:

sudo ifconfig eth0 192.168.1.100 # by default the router use the 192.168.1.1 ip
sudo dnsmasq -d --enable-tftp --tftp-root=`pwd`

For example this will result in:

CFE> flashimage openwrt-AGV2+W-cfe-jffs2-128k-cfe.bin

Network/Led configuration as Access Point

I can suggest you to use Alice gate with the following network configuration using serial console:
