How to install Technotrend Budget S2-1600 card on mythbuntu? - 14-April-2010, 15:44

Hi everyone,
I'm trying to install a Technotrend Budget S2-1600 card on mythbuntu but it's not recognized in Mythtv.
Some people say on other forums that it should work with the default v4l drivers since at least ubuntu 9.04.
A /dev/dvb/adapter0/ folder have been created but the frontend0 file is not there, there are only demux0, dvr0 and net0.
In a previous Mythbuntu install, dvbtools asked me for this frontend0 file so I assume there is a problem with the device's nodes.
Now, I can no more install mercurial which is asked for in v4l/dvb tutorials: the packet is not available, even if I have Universe repository uncommented.
By the way, shouldn't it be a v4l/ folder rather than a dvb/ one?


Can anyone help me, please?

The SAA7146 is supported by Manu Abraham's driver ([[1]]). Some people in this (german) VDR board added this card to the driver at the end of april 2009. One Day later the development was committed to http://linuxtv.org/hg/v4l-dvb.

However, this is still some initial support an might need some more testing.

Thanks for your answer.
I had already seen this page but what should I do? Contact the developper?

I finally managed to install mercurial and then v4l-dvb latest drivers and dvb-apps tools. (Don't know exactly why this wasn't working, maybe SSH or root user. I worked with user+sudo directly on the server.)
But the problem seems to be at device node creation point: the frontend0 file is still missing in my /dev/dvb/adapter0/ folder after reboot and dvbscan asks for it:
Code:
[email protected]:/$ dvbscan
Failed to open frontend
These mod are active with a lsmod:
Code:
budget                 15375  1 
budget_core             9632  1 budget
saa7146                18116  2 budget,budget_core
ttpci_eeprom            2076  1 budget_core
dvb_core               87364  2 budget,budget_core
So I assume the v4l-dvb drivers are ok.
Then I don't know where to check what's going on with this frontend creation.
Maybe udev?
Anyone else?


PS: I had some errors in v4l making process, mainly with v4l/firedtv-1394.c. I have onboard firewire but I don't know it has anything to do with my actual sat card problem.

first you need to disable firedtv support (this has nothing to do with firewire. therefor type instead of make make menuconfig, find it on the list under DVB devices and disable it. save alternate config and then make make install.

after done make a reboot and check dmesg for DVB devices. if still not working try to manually load the driver via modprobe and recheck.

Hi himself
I remade v4l with disabled firedtv (BTW it seems to have something to do with firewire since it's listed under "firewire adapters") and et61x251 as it produced an error too. Then rebooted but nothing changed. Frontend0 is still not created.

Here are lines of dmesg about saa7146 and dvb but I don't know what it means at all:

As I said earlier, there are active modules for saa7146/dvb:
Code:
budget                 15375  1 
budget_core             9632  1 budget
saa7146                18116  2 budget,budget_core
ttpci_eeprom            2076  1 budget_core
dvb_core               87364  2 budget,budget_core
What should I load with modprobe?
And again what about this frontend0 file? When and by what should it be created?

a liitle late but try the following:

cd /usr/src
hg clone http://powarman.dyndns.org/hg/v4l-dvb
cd v4l-dvb
make
make install

your problem is in this line:

[ 8.653665] DVB: Unable to find symbol stv090x_attach()

Hi himself,
Not too late because I'm still stuck with that ?!%# problem. Thanks.
...but it didn't work.
What did you change in this other source?

Thank you for spotting the line too.
It leads to the same spot people on mythtv forums pointed to me: it looks like the driver/frontend (I don't know exaclty what it does) is not working for the tuner (ST STV6110A) and/or demodulator (ST STV0903B) show on the card page at v4l.
When I look at lsmod, only SAA7146 stuff are loaded. Modules STV6110 and STV0900 (which should be compatible with STV0903 according to the v4l page) are installed but do nothing when manually launched with modprobe.

Should I do something beyond launching these modules to make them "active"... and create this mythic frontend?

yip try to insmod them! that forces them to load! unfortunatly i am not that much of an expert in linux as well. but this is how i convinced my skystar hd2 to start working. simply type : insmod driverfile.ko

this might be wrong though...

Well, still not working...
Insmod only loads the modules like modprobe.
Thanks anyway.
I think I'll wait until april 29th to install ubuntu 10.04. Maybe it will fix my problem...
