That's great!
This part of the ivtv system was poorly documented when I did my setup last August, and I guess it's still not perfect yet.
Yeah. The documentation only describes how to set up modules for a properly configured system. ;) See messages inline...
Because everyone top-posted.
Why is it so hard to figure out the flow of this thread?
This tuner is type 50, not type 39. By setting it to use type 39, you are preventing reception of any channel > 61 (cable) (and I don't remember channel number for OTA, but it's rather low). You really need to use type 50 with a recent-enough tuner module (which, BTW, is distributed with 2.6.10, so it's already on Chris's system).On Feb 7, 2005, at 6:22 PM, Chris wrote:
Thanks, problem solved!

Specifying options for the tuner module is deprecated. Specifying a tuner option for ivtv is only required if your system is improperly configured--it will autodetect the tuner type.This is what I had to do:
options ivtv tuner=39 debug=0 options tuner type=39
Actually, you should *not* specify a type option for the tuner module (ever!!!). (And, remember the above about autodetection for ivtv...)
the trick is that tuner needs to have the same type as ivtv, otherwise your tuner wont tune. hence the snow. This took me a zillion years to figure out.
This is the real problem. Because of the current system configuration, the tveeprom module is failing to load properly. Because ivtv uses information from tveeprom to determine the proper settings for the card, autodetection fails to work when tveeprom fails to load. Therefore, if you fix the problem that's causing tveeprom to fail to load, you can get rid of all your incorrect module options...On Jan 31, 2005, at 3:03 AM, Dybdahl, Niels wrote:
thanks very much for your feedback everyone. i might be making progress
here... i made the alias in /etc/modprobe as instructed:
alias tveeprom tveeprom-ivtv
and then: # depmod -a
i then tried to load the modules: # modprobe -r ivtv # modprobe tveeprom # modprobe ivtv
although no errors are returned, the tveeprom module doesn't seem like
it really loads.
the prompt comes back instantly, without any pause or disk activity. i
tried the alias just before the other ivtv modules, as well as at the
first line of the file
i get the same errors in dmesg:
ivtv: i2c client addr: 0x50 not found! ivtv: Error -19 reading Hauppauge eeprom. ivtv: Possible causes: the tveeprom module was not loaded, or ivtv: the eeprom kernel module was loaded before the tveeprom module.
The most common reasons why tveeprom fails to load are:
- Lack of i2c support in the kernel (not the problem here)
- Using the wrong tveeprom (i.e. should be using tveeprom-ivtv when using Axel's RPM's)
- Loading the eeprom module before loading tveeprom (as described in the error message)
- Using other drivers that require i2c and that conflict with tveeprom (i.e. lmsensors)
- Failing to install all required modules (i.e. modules distributed with the kernel on which ivtv depends).
- Using modules for the wrong kernel version.
i tried an arbitrary reboot, but it didn't help (hehe, that only works on windows :)
i also tried Geir Ertzaas' suggestion for building the tveeprom module into an initial ramdisk:
# mkinitrd -f --with=tveeprom-ivtv initrd-`uname -r`.img `uname -r` # cp
./initrd-2.6.10-1.737_FC3.img /boot/initrd-2.6.10-1.737_FC3.img
then i grep'd this in /var/log/messages: Jan 28 23:58:05 localhost kernel: tveeprom: no version for "struct_module" found: kernel tainted.
Sure you have the right modules installed?
I highly recommend fixing the problem (not being able to install tveeprom) instead of just masking the symptom (failure to autodetect tuner type and other card settings). I especially recommend doing so rather than masking the symptom with incorrect settings... ;)
HTH.

if anyone knowns where i might go from here, please drop me a line. thanks again for taking the time to read and make suggestions folks :>
