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

Added by Mike A over 10 years ago

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??

RE: Building V4L-DVB with kernel 3.14.1 - fails? (TBS 6980) CX23885 -FIXED!!! - Added by Mike A over 10 years ago

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 :)
