2. Siemens Gigaset SX551
The Siemens Gigaset SX551 is an WLAN DSL Router. This device is also distibuted with a modified firmware by the Dutch provider KPN as the first generation Experia box (silver version). This is the version I (SA007) have.
3. Basic hardware info
The device has the following connectors on the rear (left to right).
Auxiliary antenna.
Telephone 1 connector (POTS).
Telephone 2 connector (POTS).
Line connector (Fallback).
ADSL input connector.
4 numbered RJ45 10/100 MBit connectors.
One USB 2.0 Port (2nd can be added with soldering).
Reset button.
Large On/Off button.
Power connector (12V 1.2A).
Main antenna.
It supports ADSL/ADSL2/ADSL2+ connections, WEP/WPA. Standard the USB port can be used for a fileserver (FAT only) or a very small number of printers.
4. Opening the casing
First remove the 4 screws on the bottom site (inside the U shaped anti-skid pads). Around the device there are 5 clips, to click them open you must pull the underside outward. The clips are:
Rear.
Above the reset button.
Sides.
Centered.
Front.
Around OK LED.
Around Tel1 LED.
5. Extended hardware information
5.1. Main processor
The main processor is an Texas Instruments TNETD7300AZDW Processor, covered by a soldered in place cooler, an AR7 that should work with the AR7Port of openWRT (yet untested).
5.2. Memory
Onboard is a PSC A2V46S40BTP 256Mbit (32MiB) SDRAM Memory chip.
5.3. Flash
The flash chip is an Excelsemi ES29LV160DB-70RTG 16Mbit (2MiB) 3.0V Flash memory, hopefully this is enough for OpenWRT.
5.4. USB 2.0 Controller
The device probably will not have any USB problems since the USB controller is a seperate chip. The controller is a VIA VT6212L. A 4-port USB 2.0 Host controller. Unfortunatly only one port is external by default, but this can be expanded to 2 ports by adding some components and a larger connector, as soon as this works it will be posted here.
5.5. VoIP Controller
VoIP is done by a VoicePump VP101X12DQC Chip (located at the bottom side of the PCB). This chip is not yet supported. An LegerIty Le9502BTC Provides a ringing interface circuit. Some other inferfacing is done by a LiteLink CPC5621A Phone Line Interface IC Both seem to connect to the VoicePump.
5.6. Switch chip
The internal switch is a Marvell 88E6060-RCJ1 6-port (4 external, 1 to the router itself, 1 unused) 10/100 switch with autosensing.
5.7. Wireless card
I removed the wlan card from the SX551 and plugged it into my laptop:
# lspci

# lspci -n

Interrupt: pin A routed to IRQ 11

Status: D0 PME-Enable- DSel=0 DScale=2 PME-
Which means it is an normal Atheros card which should work flawlessly with MadWifi.
5.8. Hardware with unknown function
Texas Instruments TNETV100PZ, probably some sort of companion chip of the AR7.
This may be a VLYNQ to PCI bridge, used for the WiFi and USB controllers.
6. Pinouts
I'm still figuring out pinouts. Most headers are useless and only used to glue the wireless wires to.
Userless headers:
P1 - Next to the wlan card.
P2 - At the far side of the wlan card.
P3 - At an slight angle nest to the 4-port RJ45 block.
P4 - In the corner of the auxilery antenna.
P5 - Between the USB 2.0 controller and the main processor.
JP4 - 4 Pin, directly connects to the Line port on the rear of the modem. J4 - 10 Pin. Serial console.

RXD.

TXD.

Gnd.
+3.3V.
7. Serial console
A serial console can be conneced to J4, according to the pinout above.
The serial signals are at a 3.3V level, so you need to use a level convertor, see OpenWrtDocs/Customizing/Hardware/Serial Console
The serial signal itself is 115200 baud, 8 databits, 1 stopbit, no parity (8N1).
8. Original bootlog
===========================================================

That really is all...
There is a debug console which can be reached by pressing the reset when you start de device and then pressing the reset three times after that. (tnx equinoxe for that tip)
Then the output becomes:

In this mode it does respond to some input.
Pressing u or U gives a list of some (non-intresting) debug info about transmitted and received packets.
Those are the only 2 ascii characters the console responds to with a message other than "I'm still alive ..." |
