hi, i have followed every post here to get my card working but with no luck.

I also use a avertv dvb-t card but i cant get the frontend working.
Also where you all have.

ok, this is how it is, i just found out that i have a AverTV DVB-t 771 card that uses MT352 as demodulator instead of Microtune 7202D.

EDIT:

Ive got the frontend working
What i did was:

Get the latest linuxtv-dvb source

I got same DVB-T card as the_weird, also with MT352 onboard.
dmesg shows the card correctly, but its unable to tune to any channel. The scan programm isnt working too. Ive noticed that there is no output in dmesg that the firmware gets loaded. Hotplug is running.

I'm getting errors with the latest DVB CVS snapshot...I have a 771 card and followed your advice, the_weird, but am getting warnings when compiling the kernel and the following when insmodding the modules:

Right. I had the wrong card selected in the kernel config :oops:

, but also I checked out the CVS snapshot from around the same time as the people above, with:

I've also got a DVB-T 771 card.

Thanks for the info the_weird, very helpful.

Unfortuanately, the current (as of 19/7/04) cvs code for mt352 segfaults, for me. I've gone back a revision or two, and it loads fine, but I get the same tuning problem as devzero_DE.

Anyone aware of a solution?

I know in my case that it isn't a signal problem, as the same card/antenna setup works fine in windows.

EDIT - I just knabbed a channels.conf that someone else had done for Brisbane, and it works a treat

I've got a AverTV DVB-T card that has been sitting in a windows machine for a while, and I want to see if it will work through linux, but I'm not having much luck.

I have recently emerged linux 2.6.10 r4 from gentoo-dev-sources.

dmesg:

I, and a few other people on here have been having a problem with i2c when trying to get avermedia dvb cards working.

Im my case the error im getting is:

i2c_adapter i2c-4: sendbytes: error - bailout.

This appears when you attempt to test the card and it uploads the firmware. This is obviously a problem, because the turning details etc are sent using i2c.

Anyone know how to fix this?

Uh, I am sure that the message is not the problem:

I have this come up, whenever I use the dvb card:

Thanks, I have made it work now, although it took some random messing.

For the benefit of anyone else trying to make the Aver DVB-T work, ill say what I did.

Its working for me, with 32bit gentoo-dev-sources 2.6.10-r6 (by which I mean it finds channels with the scan unitlity, though I havnt yet put X on here to see the results)

Firstly set up your kernel properly. Ive included my complete kernel config at the bottom, the most important sections are the I2C and the DVB ones. They are similar to the other posts on here, but there might be one or two odd differences.

Ill assume thats working fine for you. When you start the system up, you should see lines in your dmesg from bttv and things registering the adaptor. A quick check with ls /dev/dvb/ should show adaptor0, and ls /dev/dvb/adaptor0/ should show demux0 dvr0 frontend0 net0

If you have more than one dvb card that might vary. If those dont show up then your card isnt working properly with the kernel, so try a few different combinations of enabling bt878 support before and after other options and try using modules.

Firstly, for those of you who dont have the scan utility, you need to download the linuxtv-apps. You can get these from http://linuxtv.org -> Downloads -> DVB and then the apps file.

Youll need to untar it with tar -xjf [name of the linux apps tar file]

Once youve done that, cd into the folder thats appeared, then into util, and then scan.

Run 'make' in the scan folder.

Now before we can go any further you need the firmware for the card. Theres a perl script in /usr/src/linux/Documentation/dvb. cd there and use perl get_dvb_firmware sp887x. At this point it may say you dont have some programs, emerge those and youll be fine. Once it has downloaded and extracted the firmware from the avermedia drivers, youll have a file called something like dvb-fe-sp887x.fw. At this point you should check if you have hotplug installed, and running, if not do so now.

Now the firmware needs to be copied to /usr/lib/hotplug/firmware/ but in my case this was not enough. The firmware is loaded the first time you try to use the card when the machine has been booted, so this doesnt happen on startup - you have to run something like scan before it tries. I also had to mkdir /lib/firmware and copy the firmware there. I left the copy in the hotplug firmware directory in case this suddenly is needed - but in my case the firmware was not found there, and I had to make the other directory myself.

At this point, you should have the firmware in the right place(s) , have the right stuff in dev, have the scan utility compiled, and have hotplug running. Now to use scan, change to the scan directory from before and use ./scan dvb-t/[transmitter name] where the transmitter name is one of the files there. In my case again (being in wales) our transmitter wasnt there - instead i downloaded the right file from the excellent www.mikeasoft.com (thanks Mike), you probably wont need to.

If you scan using the wrong file I have found it says tuning failed a bit, and doesnt do much, so that may not indicate the card isnt working.

If it finds channels, well done, it works, and theres plenty of guides that say how to turn the outout into a channels.conf for use with xine or whatever.

If it doesnt work, try dmesg and see what the output at the bottom is. I get a strange moan about i2c sendbytes and bailing out, that doesnt affect the card working (which kept me occupied for days!).

I hope this helps anyone who stumbles accross it trying to get the card to work, and hopefully you wont have to trawl through those linuxtv mailing list archives that google keeps returning - uggggghhhh

Am trying to get an Avermedia 771 installed and running. Have been following a number of the posts in this thread. I have succeeded in compling the kernel (2.6.10-gentoo-r6) but am using recent cvs dvb modules from linuxtv.org. The dvb stuff is compiled as modules. I am able to modprobe all the modules, and can then see /dev/dvb/adapter0, with frontend0, demux0, net0, dvr0 devices all present. Hotplug is installed.

However when I try to tune the card using the scan utility it says tuning failed for all channels. I have checked the channel frequencies aganist www.dba.org.au (I'm in Sydney Australia, north shore).

I got suspicious that my firmware might not be loading, since not having the firmware present seemed to make no difference to the result of modprobe. Subsequently turned on debugging in /etc/hotplug.d/default/hotplug.default, and sure enough hotplug is logging errors in /var/log/everything/current. A lot of errors like

"no runnable /etc/hotplug/dvb.agent is installed"
"no runnable /etc/hotplug/parameters.agent is installed"

So:

1) How do I know if hotplug is loading the firmware correctly? Anyone got an example dmesg or log message?
2) Am I missing some hotplug agent scripts?

EDIT 20 Feb 2005: Obviously a red herring - got it working despite these messages.
