LifeView LR506

LifeView LR506 USBstick

This is a DVB-T USB receiver from LifeView and is sold in Europe for about 25€.

This device, which was labeled only with the type-name "LR506", is most likely the TV Walker Q DVB-T, which is also known as model LR506Q. This is collaborated with, in addition to visual similarities, by the fact that a LifeView press release (PDF) refers to the LR506 belonging to the "Q-Series".

The device is currently not supported (for more information see below).

Hardware Components

• NXP/Philips 8275AC1 (tuner)
• NXP/Philips TDA10046HT (demodulator)
• Cypress CY7C68013A (i.e FX2) (USB bridge)

Support Status

So far there has only been a little progress towards getting this Stick supported. At the time of writing, it is possible to get the Stick into a "warm-state" with a modified m920x.c-driver and a special firmware:

Experimental Driver & Firmware

• patch against ddbf21fbe99c (this includes/modifies the patch from http://www.rasterburn.org/~aet/m920x/m920x-twalker-rl506.patch)
• Firmware

Note: While the TV Walker Twin and LR506 are similar in that they use the same tuner and demodulator, the TV Walker Twin uses a ULi M9206 USB bridge whereas this device uses the Cypress FX2. Further investigation towards supporting this device should focus upon the FX2, and its firmware handling, as it is utilised in numerous devices already supported under Linux!

Work in Progress

Analysing the i2c bus showed that the devices have following addresses:

0x08 ... TDA10046
0x50 ... the i2c EEPROM (holding the USB-ID for the FX2)
0x60 ... 8275AC1
