    Привет Гога
    Испытано на b2c2 об 2.6x и TT-S3200, и она работает, как ожидалось.
    Большое спасибо Игорю за поддержание слияния.
    Вы можете использовать следующие канал, чтобы отслеживать изменения

    :


    Гога я конечно понимаю твою радость
    но в двух словах
    в отличие драйверов Игоря ,от обычных имеется виду скай стар2(b2c2)?

    Как известно, у меня нет HVR-4000 (не LITE), соответствено, я не могу уверенно отвечать на многие вопросы. А мне их задают по почте. Поэтому сам хочу спросить, кто-нибудь проверял, работает ли DVB-T. Теоретически

    Исходный код
    modprobe cx88-dvb frontend=1


    и все должно быть OK

  • Igor, I thank you for the great drivers.


    From revision 9564 they stopped work with my TT S2-3200. The problem affects only
    DVB-S2/8PSK, not DVB-S/QPSK. If I can help somehow, let me know.

  • Strange. Right now I've scan DVB-S2/8PSK broadcasts. Seems OK.

    My card works only with

    Исходный код
    .hi_clk			= 99000000


    and not with

    Исходный код
    .hi_clk			= 135000000,


    lspci output:

  • Hi, Igor.
    This weekend I tested almost all revisions of your tree. I have managed to locate the source of my rotor issuses. It is revision 9564. Up to this revision rotor works, but tuning is erratic. After that rotor stops working but tuning is almost perfect. Latest changes to .hi_clk you have made, seem to fix the issue with the rotor but tuning is worse. Especially if I try to drive the rotor and then tune. Situation is almost like before revision 9564.
    These are my experiences with my hardware. At least I managed to ascertain that the card is ok and that it is a problem with the driver.
    I saw Manu's post on the mailing list that higher values of .hi_clk may damage the chip, but in my case, it is crucial in getting stable lock. The unfortunate downside is that it somehow breaks rotor support.

  • I hope you figure it out because it is such a hassle turning my dish. I have to change cables and use my ss2.
    After my weekend trials I ended up using revision 9571, the one before the implementation of the very high clock. It is the latest with which I have stable lock. Rotor control doesn't work but I can use the card to actually watch dvb-s2 instead of just keeping a useless piece of hardware inside my computer. :)

  • hi igor,
    i managed to register here... blindly... because i don't understand a word in russion :-)
    however, i have been trying for quite a while now to get the DVB-S2 driver working with a Technotrend S2 3600 USB card on a PS3.
    It basically works, because a friend of mine got it working on a PS3 as well, but it doesn't work for me.
    Here is what I did.
    I have a new Fedora 9 installation, updated the kernel to the latest 2.6.28-rc9 (without any v4l stuff enabled in the kernel config).
    I then downloaded your latest v4l repository.
    and installled it.
    The driver seems to load fine when i attach the card:


    usb 1-2.4: new high speed USB device using ps3-ehci-driver and address 9
    usb 1-2.4: configuration #1 chosen from 1 choice
    dvb-usb: found a 'Technotrend TT Connect S2-3600' in warm state.

    but when I try to do zap with szap-s2 I get:
    ioctl32(szap-s2:5094): Unknown cmd fd(3) cmd(80086f52){t:'o';sz:8} arg(ff920090) on /dev/dvb/adapter0/frontend0


    same with scan-s2:
    ioctl32(scan-s2:5151): Unknown cmd fd(3) cmd(40086f53){t:'o';sz:8} arg(fffed248) on /dev/dvb/adapter0/frontend0


    so, something is wrong here... but what the heck????


    I already posted to the dvb mailing list, but nobody was able to help me.
    just goga pointed me to this board.


    Hope you can help me, Igor. Thanks in advance.

  • i found out in the meantime that the ioctls in the combination 64 bit kernel and 32-bit szap-s2 don't work.
    I now compile szap-s2 as a 64 bit app and i can tune channels...
    i suspect that this is a driver problem because i have a ps3eye driver working on a 64 bit kernel using a 32 bit app.
    maybe you can have a look and fix it.
    thanks.

  • it also looks like the initialization of the stb0899 is not perfect yet...
    i have a lot of ts discontinuties. so, that the mpeg decoder issues a lot of error messages on regular dvb-s channels.

  • What about TeVii S420 ?
    I use s2-liplianin-92ef6cc853a6 driver
