This howto describes how to get the Terratec Cinergy 1200 DVB-T/DVB-C working in Linux.
Activating the needed kernel options
In this howto the 2.6.12 Kernel is used, it should work with every 2.6er kernel. First run the kernel configuration:
cd /usr/src/linux && make menuconfig
Then activate the needed kernel options.
Device Drivers ---> Generic Driver Options ---> <*> Hotplug firmware loading support Multimedia devices ---> <*> Video For Linux Video For Linux ---> <M> Philips SAA7134 support <M> DVB Support for saa7134 based TV cards Digital Video Broadcasting Devices ---> [*] DVB For Linux <*> DVB Core Support <M> Budget cards <M> Budget cards with analog video inputs Customise DVB Frontends ---> <M> Philips TDA10045H/TDA10046H based
Compile and install the Kernel. If hotplug is not installed:
Getting and installing the needed firmware
Not needed for Terratec Cinergy 1200 DVB-C.
The kernel module needs the firmware loaded by hotplug. To download the firmware do this command:
cd /usr/src/linux/Documentation/dvb && perl get_dvb_firmware tda10046
This will download the firmware and save it to: dvb-fe-tda10046.fw
Copy it to /lib/firmware with:
cp /usr/src/linux/Documentation/dvb/dvb-fe-tda10046.fw /lib/firmware/
Note: Do not forget the trailing slash, as otherwise cp may produce a file, not directory, /lib/firmware!
After booting the new kernel
Load the kernel modules:
modprobe budget modprobe budget-av
After this ls /dev/dvb/adapter0/dvr0 should show the device node.
Now you can use your favorite program, I suggest kaffeine.
Dmesg shows the following output:
tda1004x: waiting for firmware upload (dvb-fe-tda10046.fw)... tda1004x: no firmware upload (timeout or file not found?) tda1004x: firmware upload failed
Shows that the firmware is not loaded. Maybe the firmware is at the wrong place. You can find the directory where hotplug searches for the firmware with the following command:
grep FIRMWARE_DIR /etc/hotplug/firmware.agent
Also see external links for other reasons that the firmware may not load
Firmware not loading
firmware not loading thread - Root cause of this is that hotplug is calling /sbin/udevsend instead of /sbin/hotplug:
# cat /proc/sys/kernel/hotplug /sbin/udevsend
(on a 2.6.11 kernel)
/dev/dvb/ does not appear
Newest Cinergy 1200 DVB-C cards are shipped with a little different chipset (frontend is TDA10023 instead of the older TDA10021). The new frontend still isn't (May 11th 2007) supported in the stock Linux kernel. Fortunately there is working support in the developement version of v4l sources (see this page, external patch is no longer needed).
Short installation instructions for Gentoo:
emerge -av mercurial (install Mercurial software which is needed for transfering the sources) cd /usr/src (move to system's kernel source directory) hg clone http://linuxtv.org/hg/v4l-dvb (download v4l-dvb sources via Mercurial) cd v4l-dvb (move to the source directory) make (compile the v4l-dvb sources) make install (install compiled driver modules)
Because it replaces original kernel modules, it is recomended that in kernel everything related to v4l and dvb is compiled as modules.
At least earlier that patch had one problem, it eats all CPU power. If you have one CPU, your load is something over one (~1.10), with two CPU's load goes over two (~2.20). I'm not sure about the current situation.
You need to install media-tv/linuxtv-dvb-apps to get applications to tune card and you also need to get initial tuning data from provider. Some of tuning data is provided with tools, but not all. Ask service parameters from operator.
Initial tuning data looks like that:
# DVB-C, Tikka Media, Joensuu, Finland # freq sr fec mod C 162000000 6900000 NONE QAM128 C 418000000 6900000 NONE QAM128
dvbscan -c initial-tuning-data-file > ~/.czap/channels.conf. You can also use dvbscan to make channel tuning to mplayer, xine and vdr.
