How to get the Nebula, PCTV, FusionHDTV Lite and Twinhan DST cards working
|
||||
==========================================================================
|
||||
How to get the bt8xx cards working
|
||||
==================================
|
||||
|
||||
This class of cards has a bt878a as the PCI interface, and
|
||||
require the bttv driver.
|
||||
1) General information
|
||||
======================
|
||||
|
||||
Please pay close attention to the warning about the bttv module
|
||||
options below for the DST card.
|
||||
This class of cards has a bt878a as the PCI interface, and require the bttv driver
|
||||
for accessing the i2c bus and the gpio pins of the bt8xx chipset.
|
||||
Please see Documentation/dvb/cards.txt => o Cards based on the Conexant Bt8xx PCI bridge:
|
||||
|
||||
1) General informations
|
||||
=======================
|
||||
|
||||
These drivers require the bttv driver to provide the means to access
|
||||
the i2c bus and the gpio pins of the bt8xx chipset.
|
||||
|
||||
Because of this, you need to enable
|
||||
"Device drivers" => "Multimedia devices"
|
||||
=> "Video For Linux" => "BT848 Video For Linux"
|
||||
|
||||
Furthermore you need to enable
|
||||
"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"
|
||||
=> "DVB for Linux" "DVB Core Support" "BT8xx based PCI cards"
|
||||
Compiling kernel please enable:
|
||||
a.)"Device drivers" => "Multimedia devices" => "Video For Linux" => "BT848 Video For Linux"
|
||||
b.)"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"
|
||||
=> "DVB for Linux" "DVB Core Support" "Bt8xx based PCI Cards"
|
||||
|
||||
2) Loading Modules
|
||||
==================
|
||||
|
||||
In general you need to load the bttv driver, which will handle the gpio and
|
||||
i2c communication for us, plus the common dvb-bt8xx device driver.
|
||||
The frontends for Nebula (nxt6000), Pinnacle PCTV (cx24110), TwinHan (dst),
|
||||
FusionHDTV DVB-T Lite (mt352) and FusionHDTV5 Lite (lgdt330x) are loaded
|
||||
automatically by the dvb-bt8xx device driver.
|
||||
In default cases bttv is loaded automatically.
|
||||
To load the backend either place dvb-bt8xx in etc/modules, or apply manually:
|
||||
|
||||
3a) Nebula / Pinnacle PCTV / FusionHDTV Lite
|
||||
---------------------------------------------
|
||||
$ modprobe dvb-bt8xx
|
||||
|
||||
$ modprobe bttv (normally bttv is being loaded automatically by kmod)
|
||||
$ modprobe dvb-bt8xx
|
||||
All frontends will be loaded automatically.
|
||||
People running udev please see Documentation/dvb/udev.txt.
|
||||
|
||||
(or just place dvb-bt8xx in /etc/modules for automatic loading)
|
||||
In the following cases overriding the PCI type detection for dvb-bt8xx might be necessary:
|
||||
|
||||
2a) Running TwinHan and Clones
|
||||
------------------------------
|
||||
|
||||
3b) TwinHan and Clones
|
||||
$ modprobe bttv card=113
|
||||
$ modprobe dvb-bt8xx
|
||||
$ modprobe dst
|
||||
|
||||
Useful parameters for verbosity level and debugging the dst module:
|
||||
|
||||
verbose=0: messages are disabled
|
||||
1: only error messages are displayed
|
||||
2: notifications are displayed
|
||||
3: other useful messages are displayed
|
||||
4: debug setting
|
||||
dst_addons=0: card is a free to air (FTA) card only
|
||||
0x20: card has a conditional access slot for scrambled channels
|
||||
|
||||
The autodetected values are determined by the cards' "response string".
|
||||
In your logs see f. ex.: dst_get_device_id: Recognize [DSTMCI].
|
||||
For bug reports please send in a complete log with verbose=4 activated.
|
||||
Please also see Documentation/dvb/ci.txt.
|
||||
|
||||
2b) Running multiple cards
|
||||
--------------------------
|
||||
|
||||
$ modprobe bttv card=0x71
|
||||
$ modprobe dvb-bt8xx
|
||||
$ modprobe dst
|
||||
Examples of card ID's:
|
||||
|
||||
The value 0x71 will override the PCI type detection for dvb-bt8xx,
|
||||
which is necessary for TwinHan cards. Omission of this parameter might result
|
||||
in a system lockup.
|
||||
|
||||
If you're having an older card (blue color PCB) and card=0x71 locks up
|
||||
your machine, try using 0x68, too. If that does not work, ask on the
|
||||
mailing list.
|
||||
|
||||
The DST module takes a couple of useful parameters.
|
||||
|
||||
verbose takes values 0 to 4. These values control the verbosity level,
|
||||
and can be used to debug also.
|
||||
|
||||
verbose=0 means complete disabling of messages
|
||||
1 only error messages are displayed
|
||||
2 notifications are also displayed
|
||||
3 informational messages are also displayed
|
||||
4 debug setting
|
||||
|
||||
dst_addons takes values 0 and 0x20. A value of 0 means it is a FTA card.
|
||||
0x20 means it has a Conditional Access slot.
|
||||
|
||||
The autodetected values are determined by the cards 'response string'
|
||||
which you can see in your logs e.g.
|
||||
|
||||
dst_get_device_id: Recognise [DSTMCI]
|
||||
|
||||
If you need to sent in bug reports on the dst, please do send in a complete
|
||||
log with the verbose=4 module parameter. For general usage, the default setting
|
||||
of verbose=1 is ideal.
|
||||
|
||||
|
||||
4) Multiple cards
|
||||
--------------------------
|
||||
|
||||
If you happen to be running multiple cards, it would be advisable to load
|
||||
the bttv module with the card id. This would help to solve any module loading
|
||||
problems that you might face.
|
||||
|
||||
For example, if you have a Twinhan and Clones card along with a FusionHDTV5 Lite
|
||||
|
||||
$ modprobe bttv card=0x71 card=0x87
|
||||
|
||||
Here the order of the card id is important and should be the same as that of the
|
||||
physical order of the cards. Here card=0x71 represents the Twinhan and clones
|
||||
and card=0x87 represents Fusion HDTV5 Lite. These arguments can also be
|
||||
specified in decimal, rather than hex:
|
||||
Pinnacle PCTV Sat: 94
|
||||
Nebula Electronics Digi TV: 104
|
||||
pcHDTV HD-2000 TV: 112
|
||||
Twinhan DST and clones: 113
|
||||
Avermedia AverTV DVB-T 771: 123
|
||||
Avermedia AverTV DVB-T 761: 124
|
||||
DViCO FusionHDTV DVB-T Lite: 128
|
||||
DViCO FusionHDTV 5 Lite: 135
|
||||
|
||||
Notice: The order of the card ID should be uprising:
|
||||
Example:
|
||||
$ modprobe bttv card=113 card=135
|
||||
$ modprobe dvb-bt8xx
|
||||
|
||||
Some examples of card-id's
|
||||
For a full list of card ID's please see Documentation/video4linux/CARDLIST.bttv.
|
||||
In case of further problems send questions to the mailing list: www.linuxdvb.org.
|
||||
|
||||
Pinnacle Sat 0x5e (94)
|
||||
Nebula Digi TV 0x68 (104)
|
||||
PC HDTV 0x70 (112)
|
||||
Twinhan 0x71 (113)
|
||||
FusionHDTV DVB-T Lite 0x80 (128)
|
||||
FusionHDTV5 Lite 0x87 (135)
|
||||
