[linux-dvb] TeVii S470 Tunning Issue (Kernel 2.6.27-21)

[linux-dvb] TeVii S470 Tunning Issue (Kernel 2.6.27-21)

[Hamza Ferrag]

Hi all,

I am trying to install a 'Tevii S470' card  from TeVii technology as 
described  here http://linuxtv.org/wiki/index.php/TeVii_S470.

My configuration is :

- intel x86 platform
- Kernel 2.6.27-21
- tevii_ds3000.tar.gz (firmware archive from 
http://tevii.com/tevii_ds3000.tar.gz ),
- s2-liplianin  mercurial sources ( from 
http://mercurial.intuxication.org/hg/s2-liplianin)last changes at 
05/29/2010,

All work fine i.e drivers/firmware installation after madprobe a right 
modules.

Apparently it can't locate a firmware file,  yet :

-rwxr-xr-x    1 root     root         8192 May  3 07:09 dvb-fe-ds3000.fw


Any ideas why this happens?

Thanks and best regards,

Hamza Ferrag

Re: [linux-dvb] TeVii S470 Tunning Issue (Kernel 2.6.27-21)

[Hans Houwaard]

I don't really know why, but it happens sometimes on my machine with the 
same card as well. When I have problems, I power off the computer and 
then restart it again. The card will not properly load or function 
untill I do. There is probably some hardware lock that needs to be reset 
by powering off the card.

The loading of the firmware sometimes takes a couple of seconds in my 
machine, it's not very fast. Besides check if the card, which is on a 
PCI-1x slot, doesn't share an IRQ with the onboard soundcard. That will 
seriously effect the performance of both the card and the sound.

Good luck,

Hans

TeVii S470 periodically fails to tune/lock - needs poweroff

[O&M Ugarcina]

  Hello Guys,

I have been using my TeVii S470 DVBS2 card for about one month . I am 
using it with mythtv on fedora 12 using latest kernel , and compiled the 
latest v4l drivers . The sensitivity and picture is very good both on 
dvbs and dvbs2 transponders , very happy with that . However several 
times already when trying to watch live tv on myth the channel failed to 
tune . Usually happens in the morning after box was running 24x7 for a 
few days . The only way to restore functionality is to do a power off 
and wait a couple of mins then power on . If I just do a reboot , this 
does not help . Strange thing is that I see nothing unusual in the 
mythtv logs or dmesg/messages log . When the card is in this no-lock 
state , it will not tune into any transponder even when I run scandvb . 
After power reset everything works again for a few more days . Any info 
welcome .


Best Regards

Milorad

Check the temperature of the adapter. It is getting quite hot. I use fans to 
cool it, which avoids this kind of problems.

Thanks for that Karsten,

I have checked the temperature and seems normal . It does not look
like it is getting overly hot . I have been keeping a close eye on it
and it looks like I get more failures when using Diseqc . I notice
when going to another satellite then coming back I seem to get more
no-locks . My suspicion is that there may be some issues with diseqc
function that will crash the card . After a full power down is done
card is back in operation with no problems . Could this be a firmware
thing ?

Best Regards
