Keyboards freeze after modprobe saa7134 card=81 tuner=54

English Hardware
#1

I have recently been experimenting with Gigabyte GT-PTV-TAF-RH hybrid tv card. As far as i could find out it uses Philips SAA7131E decoder and it has Philips 8275A tuner. There is also some chip which I couldn’t identify marked TDA10046A. After looking for information about it I found out that I need to load the saa7134 module with options card=81 or tiger2 reference and tuner=54 for 8275A and that I need to place dvb-fe-tda10046.fw file into /lib/firmware. So I got the firmware and started playing with the card.I couldn’t get any DVB-T reception, but analogue TV and radio worked fine.

Today while adjusting antenna I managed to get something on correct frequency using w_scan . After that, I lost signal and sometime later all I could get on analogue side was blank screen.
So I tried to put my TV card into a different slot, to see what would happen. That is when my main problem started.

I tried to load drivers with modprobe saa7134 card=81 tuner=54, and keyboards would freeze, with mouse working fine. The system wouldn’t shut down also. So I reinstalled opensuse 11.1 and returned TV card to where it was. After reinstalling I noticed that my soundcard wasn’t showing in lspci. So I swapped the TV and sound card and sound card is now working fine as far as I could see, but I am still having same problem with TV card. Here is dmesg output after modprobing TV card (shortened, so it would fit post length limit)

If I remember correctly after last line saa7134 would load firmware while everything was working correctly.

Hi
You probably need to reset the escd in the BIOS so it picks up the irq
change as you have changed pci slots.

Thank you for your reply!

It didn’t work :frowning:

I just found out that the problem is firmware related. I tried to load the saa7134 module without firmware and it loaded normally and complained about the lack of firmware. I tried to give it the firmware for tda10045 and it was accepted. My keyboards freeze for a few seconds when loading 10045 firmware, but after that everything is fine.

However I am unable to access http://www.lifeview.com.tw/ which, according to get_dvb_firmware script hosts tda10046 firmware (apparently there are two versions circulating on the net: 20 and 29 and as far as i can see 29 is from lifeview, and 20 is from techotrend). The location of TT_PCI_2.19h_28_11_2006.zip has apparently changed, as I was unable to get it from TechnoTrend AG . The firmware for 10045 could be downloaded from the same site. Could someone else try to access those sites, just to see if it’s problem on my side?

Unfortunately I can’t remember how my firmware got corrupted.

Hi
It’s available here;

Thank you very much for that link. I found TT’s site very confusing!

So the line in get_dvb_firmware that says

my $url = "http://technotrend-online.com/download/software/219/$sourcefile";

should be changed to

my $url = "http://www.technotrend.com/Dokumente/87/software/219/$sourcefile";

right?

Hi
Sorry I missed your post :frowning: Yes that would be correct. Or just download
it to the local machine?

Well, thanks again!

Now all that needs to be done is to wait for maintainers of get_dvb_firmware to update the scrips, so others wouldn’t have same problems as me.
