| 1 | How to get the bt8xx cards working |
| 2 | ================================== |
| 3 | |
| 4 | 1) General information |
| 5 | ====================== |
| 6 | |
| 7 | This class of cards has a bt878a as the PCI interface, and require the bttv driver |
| 8 | for accessing the i2c bus and the gpio pins of the bt8xx chipset. |
| 9 | Please see Documentation/dvb/cards.txt => o Cards based on the Conexant Bt8xx PCI bridge: |
| 10 | |
| 11 | Compiling kernel please enable: |
| 12 | a.)"Device drivers" => "Multimedia devices" => "Video For Linux" => "Enable Video for Linux API 1 (DEPRECATED)" |
| 13 | b.)"Device drivers" => "Multimedia devices" => "Video For Linux" => "Video Capture Adapters" => "BT848 Video For Linux" |
| 14 | c.)"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices" => "DVB for Linux" "DVB Core Support" "Bt8xx based PCI Cards" |
| 15 | |
| 16 | Please use the following options with care as deselection of drivers which are in fact necessary |
| 17 | may result in DVB devices that cannot be tuned due to lack of driver support: |
| 18 | You can save RAM by deselecting every frontend module that your DVB card does not need. |
| 19 | |
| 20 | First please remove the static dependency of DVB card drivers on all frontend modules for all possible card variants by enabling: |
| 21 | d.) "Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices" |
| 22 | => "DVB for Linux" "DVB Core Support" "Load and attach frontend modules as needed" |
| 23 | |
| 24 | If you know the frontend driver that your card needs please enable: |
| 25 | e.)"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices" |
| 26 | => "DVB for Linux" "DVB Core Support" "Customise DVB Frontends" => "Customise the frontend modules to build" |
| 27 | Then please select your card-specific frontend module. |
| 28 | |
| 29 | 2) Loading Modules |
| 30 | ================== |
| 31 | |
| 32 | Regular case: If the bttv driver detects a bt8xx-based DVB card, all frontend and backend modules will be loaded automatically. |
| 33 | Exceptions are: |
| 34 | - Old TwinHan DST cards or clones with or without CA slot and not containing an Eeprom. |
| 35 | People running udev please see Documentation/dvb/udev.txt. |
| 36 | |
| 37 | In the following cases overriding the PCI type detection for dvb-bt8xx might be necessary: |
| 38 | |
| 39 | 2a) Running TwinHan and Clones |
| 40 | ------------------------------ |
| 41 | |
| 42 | $ modprobe bttv card=113 |
| 43 | $ modprobe dst |
| 44 | |
| 45 | Useful parameters for verbosity level and debugging the dst module: |
| 46 | |
| 47 | verbose=0: messages are disabled |
| 48 | 1: only error messages are displayed |
| 49 | 2: notifications are displayed |
| 50 | 3: other useful messages are displayed |
| 51 | 4: debug setting |
| 52 | dst_addons=0: card is a free to air (FTA) card only |
| 53 | 0x20: card has a conditional access slot for scrambled channels |
| 54 | |
| 55 | The autodetected values are determined by the cards' "response string". |
| 56 | In your logs see f. ex.: dst_get_device_id: Recognize [DSTMCI]. |
| 57 | For bug reports please send in a complete log with verbose=4 activated. |
| 58 | Please also see Documentation/dvb/ci.txt. |
| 59 | |
| 60 | 2b) Running multiple cards |
| 61 | -------------------------- |
| 62 | |
| 63 | Examples of card ID's: |
| 64 | |
| 65 | Pinnacle PCTV Sat: 94 |
| 66 | Nebula Electronics Digi TV: 104 |
| 67 | pcHDTV HD-2000 TV: 112 |
| 68 | Twinhan DST and clones: 113 |
| 69 | Avermedia AverTV DVB-T 771: 123 |
| 70 | Avermedia AverTV DVB-T 761: 124 |
| 71 | DViCO FusionHDTV DVB-T Lite: 128 |
| 72 | DViCO FusionHDTV 5 Lite: 135 |
| 73 | |
| 74 | Notice: The order of the card ID should be uprising: |
| 75 | Example: |
| 76 | $ modprobe bttv card=113 card=135 |
| 77 | |
| 78 | For a full list of card ID's please see Documentation/video4linux/CARDLIST.bttv. |
| 79 | In case of further problems please subscribe and send questions to the mailing list: linux-dvb@linuxtv.org. |
| 80 | |
| 81 | 2c) Probing the cards with broken PCI subsystem ID |
| 82 | -------------------------------------------------- |
| 83 | There are some TwinHan cards that the EEPROM has become corrupted for some |
| 84 | reason. The cards do not have correct PCI subsystem ID. But we can force |
| 85 | probing the cards with broken PCI subsystem ID |
| 86 | |
| 87 | $ echo 109e 0878 $subvendor $subdevice > \ |
| 88 | /sys/bus/pci/drivers/bt878/new_id |
| 89 | |
| 90 | 109e: PCI_VENDOR_ID_BROOKTREE |
| 91 | 0878: PCI_DEVICE_ID_BROOKTREE_878 |
