Tvheadend

There is no more issue to look.

The open source driver is working good.

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

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

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

Thanks. Mac

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.

Cheers.

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 :/

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

Driver is practically finished.
(also supports TBS6980 now)

Updated the wiki with easier install and upgrade instructions.

[[https://github.com/ljalves/linux_media/wiki]]

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

Hm. Would this new driver support TBS6985 too?

//Anders

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

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

Hi Luis,

Thank you for your reply. Nice to know that officials drivers should be working.
Do you know what chipset they are using?
They seem to be relatively cheap compared to other dual-receivers. Do you think
it's a good purchase?

Regards,
Indridi

No, but 6985 performance should be good. Is for me.
