Building V4L-DVB with kernel 3.14.1 - fails? (TBS 6980) CX23885

Mike A

Hi,

I'm trying to get the TBS drivers working (the version in current kernel, not TBS's shody ones)

I've downloaded and built the latest stable kernel (3.14.1) this is fine.

https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.14.1.tar.xz

I've downloaded the latest V4L-DVB (as these modules are not in kernel.org code, right?)

http://linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers#Retrieving_and_Building.2FCompiling_the_Latest_V4L-DVB_Source_Code

However, when I run the build as below;

git clone git://linuxtv.org/media_build.git cd media_build ./build

I get errors, where it can't apply patch, and fails?

How do I get around this? I'm on the latest of both???

I removed the patch files at it compiled ok. So I'm getting closer. But now I'm stuck. I can see the cards in TvHeadend now, but the firmware does not seem to load?!?

I don't think this is related to the v4l-cx23885-avcore-01.fw. But this to this file;
/lib/firmware/dvb-fe-cx24117.fw
Because if I remove it. I get this different error;

I created the file from a post in this form that said

dd if=linux-tbs-drivers/v4l/tbs6981fe_driver.o.x86_64 of=/lib/firmware/dvb-fe-cx24117.fw

but can't find the post again now??

The other firmware I think is loading fine...

I've tried both the firmwares that comes with V4L-DBV packages and the one from the latest Linux TBS

http://www.tbsdtv.com/download/document/common/tbs-linux-drivers_v140323.zip

find / -name v4l-cx23885-avcore-01.fw -exec md5sum {} \;

b3704908fd058485f3ef136941b2e513 /lib/firmware/v4l-cx23885-avcore-01.fw b3704908fd058485f3ef136941b2e513 /usr/src/tbs/v4l-cx23885-avcore-01.fw a9f8f5d901a7fb42f552e1ee6384f3bb /usr/src/media_build/v4l/firmware/v4l-cx23885-avcore-01.fw

Just not sure where I make a valid dvb-fe-cx24117.fw, or if it's needed. Can't really find any help on this?

I think i'm getting close.

Anyone help with the last bit??

Mike A

Even though my card is a 6980

I need to used the 6981 file;

unzip -p tbs-linux-drivers_v130901.zip linux-tbs-drivers.tar.bz2 | tar jxOf - linux-tbs-drivers/v4l/tbs6981fe_driver.o.x86_64 | dd bs=1 skip=10144 count=55486 of=dvb-fe-cx24117.fw

working fine now i think.

That was a HARD SLOG!!! :)

Just googling around for you, even if I can't immediately help... a problem shared, and all that!

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

.. might be worth checking different downloads/extracted files?

Your "firmware not responding" message:

https://bugs.launchpad.net/ubuntu/+source/linux-firmware-nonfree/+bug/971951

And similar on the 24116 with link to patch:

http://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-NOVA-HD-S2

Can you rmmod/modprobe to see what happens on load/unload? Any errors there that give any clues?

I can't comment on the 23885/24117 firmware difference, I've no idea how this card presents itself. Looking at this page (http://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-HVR-1700), that card needs the multiple firmwares so it may be that the TBS unit is the same - one file for the card/bus, one for the tuners, etc.

You can download the -enc.fw and the -avcore-01.fw from here as well: http://www.linuxtv.org/downloads/firmware/#3

Bugger, so much for timing - that was a wasted bit of typing :)
