[linux-dvb] Re: AverMedia 771 DVB-T Registering frontend problem
Chris
Hurrah! Success. Key was to download and build the latest video4linux drivers
from http://dl.bytesex.org/cvs-snapshots/
Untarred it, did a make, then a make install. (Quite a lot of problems with
files missing during the make, but just copied them from the kernel source dir
into the video4linux dir that I'd untarred to and it completed successfully.)
I then tried following your earlier list of modules to install which still
didn't work but I could tell I was further ahead. So, nosing around the web, I
came across a previous posting that you'd replied to:
http://pvrguide.no-ip.com/bbs-old/viewtopic/9088.html
I followed the same module installation method that Mike listed and it started
working. Some of these didn't work, but I'll try and trim this down and post a
final summary of which modules I require
cd ~/video4linux
insmod ./video-buf.ko
insmod ./btcx-risc.ko
modprobe i2c-core
insmod ./v4l2-common.ko
insmod ./v4l1-compat.ko
modprobe i2c-algo-bit
modprobe videodev
insmod ../dvb-kernel/build-2.6/dvb-core.ko
dvb_shutdown_timeout=0 # dvb_frontend_debug=1
#michaell
insmod cx88xx.ko #core_debug=2
insmod cx8800.ko
#michaell
insmod cx8802.ko #debug=10
#michaell
insmod cx88-dvb.ko #debug=10
modprobe firmware_class
insmod ./bttv.ko
insmod ../dvb-kernel/build-2.6/bt878.ko
insmod ../dvb-kernel/build-2.6/dvb-bt8xx.ko
insmod ../dvb-kernel/build-2.6/mt352.ko
Thanks for all your help

Hold on, I just RTFM'ed (as you suggested) and found this section:
3. make
Note #1: Since the dvb-bt8xx and dst drivers now depend on a
snapshot of the v4l drivers, they are not built by default.
To build these modules do this instead: make BTTV=1
For detailed instructions for bttv based cards, see README.bt8xx
I'll do that now
Cheers

Thanks for that. I can see that the file I'm loading is:
[root@linuxpvr build-2.6]# ll
/lib/modules/2.6.8-1.521/kernel/drivers/media/dvb/bt8xx/dvb-bt8xx.ko
-rwxr--r-- 1 root root 9796 Aug 16 14:55
However, I had downloaded the latest cvs, but it doesn't seem to build the
dvb-bt8xx module file:
[root@linuxpvr build-2.6]# pwd
/root/dvb-kernel/build-2.6
[root@linuxpvr build-2.6]# ll *dvb-bt8xx*
lrwxrwxrwx 1 root root 44 Oct 16 12:11 dvb-bt8xx.c ->
../linux/drivers/media/dvb/bt8xx/dvb-bt8xx.c
lrwxrwxrwx 1 root root 44 Oct 16 12:11 dvb-bt8xx.h ->
../linux/drivers/media/dvb/bt8xx/dvb-bt8xx.h
[root@linuxpvr build-2.6]#
Do I need to compile this seperately or something?
Thanks in advance
Mike

Yes, the card you have isn't in the code you are running. I guess you are
using the current 1.1.1 release code, not the dvb-kernel CVS. The last
release was made before the 771 was around.

These messages are gone in the current code - I thought they looked
strange - which also has support for the AverMedia 771 in it.
To fetch the current CVS code, follow the instructions at
http://www.linuxtv.org/cvs/ . The module name you want to retrieve is
"dvb-kernel". Fetch this and read the instructions in the top level
README on how to build it (there is a note about building for BTTV based
cards in there).
Alternatively, you can fetch and build the current kernel (2.6.9-rc4 or
higher), which should have support in it for the 771 out of the box.

Chris
