Uwe Bugla8abe58a2006-03-16 20:37:05 -0300[diff] [blame]7This class of cards has a bt878a as the PCI interface, and require the bttv driver
8for accessing the i2c bus and the gpio pins of the bt8xx chipset.
9Please see Documentation/dvb/cards.txt => o Cards based on the Conexant Bt8xx PCI bridge:

162) Loading Modules
17==================

Uwe Bugla8abe58a2006-03-16 20:37:05 -0300[diff] [blame]19In default cases bttv is loaded automatically.
20To load the backend either place dvb-bt8xx in etc/modules, or apply manually:
Linus Torvalds1da177e2005-04-16 15:20:36 -0700[diff] [blame]21
Uwe Bugla8abe58a2006-03-16 20:37:05 -0300[diff] [blame]22 $ modprobe dvb-bt8xx
Linus Torvalds1da177e2005-04-16 15:20:36 -0700[diff] [blame]23
Uwe Bugla8abe58a2006-03-16 20:37:05 -0300[diff] [blame]24All frontends will be loaded automatically.
25People running udev please see Documentation/dvb/udev.txt.

Johannes Stezenbachdf481ae2005-05-16 21:54:45 -0700[diff] [blame]31
Uwe Bugla8abe58a2006-03-16 20:37:05 -0300[diff] [blame]32 $ modprobe bttv card=113
33 $ modprobe dvb-bt8xx
34 $ modprobe dst
35
36Useful parameters for verbosity level and debugging the dst module:
37
38verbose=0: messages are disabled
39 1: only error messages are displayed
40 2: notifications are displayed
41 3: other useful messages are displayed
42 4: debug setting
43dst_addons=0: card is a free to air (FTA) card only
44 0x20: card has a conditional access slot for scrambled channels
45
46The autodetected values are determined by the cards' "response string".
47In your logs see f. ex.: dst_get_device_id: Recognize [DSTMCI].
48For bug reports please send in a complete log with verbose=4 activated.
49Please also see Documentation/dvb/ci.txt.
