TBS6981 issues with both adaptors enabled.

Rob Hunter · 2013-05-13T21:46:46+00:00

I have spent the weekend trying to set up an XBMC / tvheadend system. A few problems, so I thought I'd share. Server System: Asus P5K Premium motherboard...

No new news I'm afraid.

I'll take the opportunity to prod TBS again.

It's a hard one to know what to do. On the one hand TBS are selling a product so should provide support. On the other hand the card works fine with vdr and other software, so the problem may be with tvheadend. As it's open source that means either fix it yourself or persuade someone who knows how to!

If I could return the TBS6981 I'd so and find something that works (see the device compatibility thread). I've had mine for too long so, as I don't possess the skills or the time to try and fix it, I'll probably switch to vdr when my system goes production over the next couple of weeks. Not my preferred solution but, hey, it works. Can't complain as I've nothing invested in tvheadend!

hummm. Sad to hear :-(

I like TVH wery much and not want to stop using it.

I think i will use only one tuner and maybe buy an extra card so i have 2 tuners.

Thanks anyway Andreas H

Guys,

Same thing happening to me with a TBS6981. Only one adapter can be used at any time. As soon as I stop playing from one adapter, the other one starts working fine.

Happy to provide logs if I can...

By the way, I just updated to the latest driver version, (130506) and the issue persist, as noted on the first post. I'll try the latest git.

I don't remember having this issue on v3.2, but to be honest, raspmbc didn't support live tv at that time :D

Hi all,

Driven by the frustration of this issue, I have developed an open source driver for the tbs6981:
https://github.com/ljalves/linux_media/wiki

I expect to get it included in the mainline kernel tree soon.

If you find any issue, please fill the form in github:
https://github.com/ljalves/linux_media/issues

Thanks and Regards,
Luis

I'd like to take a look this issue. A short while ago, can't remember which version of TVH it was, but I had six instances of XBMC running with three HD & 3 SD channels running but, speech was was only active in the first instance of XBMC. Now, with the most recent TVH it says something like both tuners are already active and won't provide any other XBMX instances with a stream. Now as I understand it the TBS6981 is good for several channel multiplex streaming. TBS say so on their site, beside I've seen it. What I wanted to prove to myself was that the 6981 could do mult-channel recording.

Now what I'm after is the Conexant CX23885-13Z full data sheet and if possible the programmers guide because without the register set info I'm stuck and I don't really want to guess what TBS's driver code is doing.

So, if anybody has a copy they could put my way or give me a link to the same it would be another pair eyes working on the issues.

Thanks one and all. Mac

Luis Alves

There is no more issue to look.

The open source driver is working good.

Mac Johnson

Hi Luis,

That's good to to hear. As I recall you said, in a previous post that's now been deleted along with
mine and others, that when you detect a 2 x 'bad' error you issue a reset. Now, is that to the 6981

as a whole or just to that tuner. What if the other tuner is recording is that effected?

Hope your answers affirmative. If so, I'll install your update

Thanks Mac

Luis Alves

Hi,

We are talking about 2 different things in here:

1) First I tryied to patch tvheadend to do what you described. Din't work very well, it still did fail sometimes.

2) I have developed a new driver for the card to replace TBS broken driver. Works like a charm.

Just install my driver and official tvheadend.

(no post has been deleted, you have 2 pages of replies)

Regards,
Luis

Mac Johnson

Luis, Thanks for the confirmation. I'll grab your modified driver from github and let you know how

it goes.

Thanks. Mac

Luis Alves

No problem.

Just to clean things out:
It's not a modified driver (TBS drivers are closed source).

It's a new driver, non-related with TBS.

Follow the instructions in the wiki and all should go well.

Regards,
Luis

Messed up my box trying to use the new driver. I'm running Ubuntu 12.04. I originally installed the TBS drivers like this:

cd ~ wget http://www.tbsdtv.com/download/document/common/tbs-linux-drivers_vXXXX.zip apt-get install -y gcc rar tar gzip aptitude install -y linux-headers-`uname -r` build-essential cvs libncurses5-dev gcc rar tar gzip unzip cd /usr/local/src/ rm tbs* -r mkdir tbs6981 cd tbs6981 unzip ~/tbs-linux-drivers_vXXXXXX.zip tar xjvf linux-tbs-drivers.tar.bz2 find linux-tbs-drivers -type d -exec chmod u+wx '{}' \; find linux-tbs-drivers -name "*.sh" -o -name "*.pl" -exec chmod u+x '{}' \ cd linux-tbs-drivers ./v4l/tbs-x86_64.sh make make install cd .. cp v4l-cx23885-avcore-01.fw /lib/firmware/

I've then followed the build and install instructions which seems to go through fine, I come unstuck at "sudo make rmmod". I was hoping a reboot would resolve but now I don't have the new adapters labelled Conexant CX24117/CX24132 as explained in the instructions and the old "TurboSight TBS 6981 DVBS/S2 frontend" no longer work. The device path, device name etc in the adapter config screens are blank.

Output of "sudo make rmmod":

Not sure how to proceed, any help appreciated.

EDIT: just noticed dmesg shows this:
[ 19.152266] cx23885: disagrees about version of symbol altera_init

[ 19.152270] cx23885: Unknown symbol altera_init (err -22)

Will try google tomorrow, tried to go back to original driver using the instructions I provided above but it didn't appear to work :/

Luis Alves

Hi,

When you get errors like "...disagrees about version of symbol..." mean that you have leftovers from old installations.
From that message you should find and remove any altera_*.ko module from your /lib/modules/..... (I bet you have same module duplicated - one new the othe the old)

And the do the "make install" step again.

If you come to tvheadend IRC channel, realtime help will be provided.

Hope this helps you.

Regards,
Luis

I noticed you mentioned something like that in the instructions but I wasn't 100%.

Anywho I did:
find /lib/modules/`uname -r` -name "altera*.ko" -exec rm -rf {} \;

sudo make install

After a reboot I now have the adapters and have copied over my muxes.

Now I'm getting this repeated over and over in tvheadend:
Jul 11 06:07:22.049 dvb: diseqc setup failed -1

Jul 11 06:07:22.093 diseqc: error trying to turn off continuous tone

I think diseqc is some kind of switch that I don't have, but I don't seem to be able to set the option to LNB as googling suggests, I can only choose "Diseqc 1.0 / 2.0" or "Diseqc 1.1 / 2.1"

Cheers.

Hi Luke,

Do you have the firmware in the right place?

https://github.com/ljalves/linux_media/wiki/CX24117-firmware

Regards,
Luis

Luis Alves

Driver is practically finished.

(also supports TBS6980 now)

Updated the wiki with easier install and upgrade instructions.

Just wanted to pop my head though the door to say thanks Luis. I was having the same issues as everyone in this thread and it was causing havoc with my schedules. Had some problems installing the drivers initially (didn't realise that the firmware step was required) but on my second attempt it worked and I've had no problems since.

Thanks very much for all your hard work on the drivers. I was going to buy another card to get around the problem, so you've saved me time, stress and money :)

Oli

Anders Falk

Hm. Would this new driver support TBS6985 too?

//Anders

Indridi Bjornsson

Hi,

What about TBS6982? Is that supported by the driver or is that something I don't have to worry about since they do not suffer from the same problems as TBS6981?

Has anyone had any experience with TBS6982?

Regards,
Indridi

Luis Alves

Hi,

The TBS6982/6985 is completely different from 6981/6984 (from a hardware point of view).

I plan to make an open source driver for the 6982 (don't know when) but you can use the official TBS drivers without any issue.

Regards,
Luis
