Siemens Gigaset C475IP base station disassembed 

At the local flea market I have found a box with an ethernet port and and a DECT logo. I have bought it just for fun hoping that I will found some kind of embedded Linux running hackable stuff inside. Well after opening it I had to became disappointed.
Just for fun and archiving puposes I post my findings here.

The board markings:
W30852-Q1813-B101-5 and





The board's heart is a PCD80725ELF ARM base microcontroller made by the NXP.

I have not found any relevant information on the web about it, so I have asked the Philips (NXP) support, and they said:

All DECT activities of Philips Semiconductors were transferred to DSP Group in 2007. http://www.dspg.com/English/ They may still have that data sheet archived.


I have contacted with the DSP Group's support but they have not answered.

The other notable parts on the board:
S29AL008 (1Mbit CMOS flash)
CY7C1041CV33 (512Kbit RAM)
Atmel AT45DB161D-SU (2 MByte SPI flash)
Atmel 24C265 EEPROM
CP2200 single chip ethernet controller by Silabs
An unidentified DECT module possibly made by the Siemens

Geovision GV-800(S) under Linux 

One of my friends asked me to get working a Geovision GV-800(S) DVR card with zoneminder.
According to the google results several people succeed with this subject. For e.g.:
http://siripong-computer-tips.blogspot. ... linux.html

I have installed a n Ubuntu 12.04 server, and the necessary packages. This distribution shuiips with a relatively new kernel (3.5.0) which means that the necessary bttv modules were included fine. The device had shown up fine: I had 4 v4l2 devices with 4 channels per each (Composite0-4). I have added these channels as sources to the Zoneminder but I have not been able to get image from them. After several trials I have installed XFCE and XAWTV. I have not been able to get image with that tool too, and at the channel changes I got I/O errors and the software claimed about invalid framebuffer address on startup.

As final trying I have installed a Windows XP to the box, and installed the Geovision software. The device had shown up in the device manager fine, but there were a yellow exclamation points next to the devices with Device cannot started message. I have seen that card working in different computer.

As a last trial we have decided to try to upgrade the BIOS, and that solved the problem.

Nokia VS JSR-234 FlashControl 

My father have a Nokia 6303i Classic, and he missed one feature from it: to be able to use the camera flash as torchlight.

According to the Device speciications, it supports the JSR-234:
http://www.developer.nokia.com/Devices/ ... i_classic/

1 Contains: CameraControl, SnapshotControl, FlashControl, FocusControl and ZoomControl

i have ditched together a small Midelt, and tried to run it on the device, but I get Flash method not supported exception.

Okay, lets check the getSupportedMethod

And the device have only one supported Flash mode the FlashControl.OFF.

I have not been able to believe it, so I have tried the Nokia C3-01 and the X2-00 at at the NOKIA RDA

But both devices produced the same behaviour.
Come on, why the hell did they implemented this API if it simply useless...
