Can't get Asus TV-FM card (SAA7135 chipset) to work with V4L drivers

JvanEkris · 08-27-2004, 07:27 AM

Hello All,

I just bought a Asus TV FM card (a visual inspection of the card revealed that it had the saa7135 chipset from Philips) for my Fedora Core
1 machine (slightly modified kernel, it is the 2.4.22 with V4L2 and lirc backported into it). I was under the impression that it was supported by Video4Linux2 drivers (the SAA7134 drivers to be precise). I did an lspci and got back this:

Quote:

01:09.0 Multimedia controller: Philips Semiconductors SAA7133
Audio+video broadcast decoder (rev f0)

When I use these settings for this card (i.e. a "modprobe saa7134
card=25") I get reported back this:

Quote:

saa7133[0]: dsp access wait timeout [bit=WRR]
saa7133[0]: dsp access wait timeout [bit=WRR]
tda9887: chip found @ 0x96

However, when I use xawtv, I do not get any stations, when I use TVTime, it says "no signal". However on a Windows XP machine with Asus drivers it works perfectly (so the card is fine).

On my google quest to solve this I did find out that this chip is indeed
reporting the wrong serial (i.e. it is reporting 7133 instead of the 7135
it really is). However, I could not find a solution to make this card work
under fedora.

Can anybody help me with getting this card to work???

Kind regards,

Jaap van Ekris

jvanekris; have u contacted asus mfg for clarification on those results that are confilcting issues with serial #,s . also note asus has support for linux,just for the asking. best to get info direct from mfg. they have better info. do not forget just because something works with w may not with linux if our developers have not yet worked on some of these devices. but they are trying to cover all devices with-in time. patients!

Hi JvanEkris,

we have this card working well with Debian Sarge, FC2, and Mandrake (tvtime; xatw does not work). This is the output of "lsmod | grep saa" in Debian:

Code:

saa7134                96748  0
video_buf              21220  1 saa7134
v4l2_common             6144  1 saa7134
v4l1_compat            14436  1 saa7134
i2c_core               24084  3 tda9887,tuner,saa7134
ir_common               4452  1 saa7134
videodev               10016  1 saa7134
soundcore              10336  6 snd,saa7134,emu10k1,sound

When I added the card to an installed Debian system, I just added it through modprobe saa7134, without any additional parameters (I also had to add tuner and other v4l modules). New installations recognized the card automatically (and even scanned channels during system setup).

If you need me to run other diagnostics, feel free to ask.

JvanEkris · 09-05-2004, 07:42 AM

If i modprobe saa7134 i do not get any errormessages. I don't know this is an improvement, but for the time being i assume it is.

Could you identify what kind of other things you have modprobed to get this card working? I'm not very familiar with hardware binding on Linux. I tried to find a working combo of the tuner and other modules. If you could clarify a bit on what modules are loaded i would be helped a lot....

You probably have something alike modules.conf that defines these hardware things (AFAIK, debian has another structure for hardware-drivers).

I think these modules are related to the card:

Code:

Module                  Size  Used by
tda9887                 7204  0
tuner                  18604  0
saa7134                96748  0
video_buf              21220  1 saa7134
v4l2_common             6144  1 saa7134
v4l1_compat            14436  1 saa7134
i2c_core               24084  3 tda9887,tuner,saa7134
ir_common               4452  1 saa7134
videodev               10016  1 saa7134
soundcore              10336  5 snd,saa7134,emu10k1,sound

So try to modprobe or insmod each of them (I'm not sure what tda9887 is) and then run tvtime again.

JoRock · 09-19-2004, 09:11 PM

I have the tvfm card too and I have all the modules you listed above but when I try to run tvtime I get the following error message:
For one I don't have the rtc module installed but also,
xvoutput: No XVIDEO port found which supports YUY2 images.
I have an ati video card with the ati drivers.
xawtv, motv,and kwintv also don't work for me. Most with v4l2 input output errors. Any suggestions?

sathia · 06-19-2005, 08:00 AM

can anyone help me?

i'm getting crazy:

and still can't get it to work. do i have to create some node on /dev?
i tried, but i always get a no signal error.
can anyone please help me?

In /etc/modprobe.conf add

options saa7134 card=X tuner=Y

For X and Y specify a value.

sathia · 06-20-2005, 04:25 AM

thank you, i'll try this. afaik the card is 25 but i can't guess the correct value for the tuner.

is there a way to know if devices are created properly under /dev/

'cause cat /dev/tuner gives error.
