[linux-dvb] Pinnacle 320e (em28xx/xc2028): scan finds just first channel

[linux-dvb] Pinnacle 320e (em28xx/xc2028): scan finds just first channel

[Miroslav Pragl - mailing lists]

Hello,
I've compiled and installed latest v4l-dvb and dvb-apps, extracted 
xceive firmware, so far so good. Distro is Fedora 11, x64 
(2.6.30.5-43.fc11.x86_64)

Unfortunately scan finds only the first channel:

$ scan  /usr/share/dvb/dvb-t/cz-Praha

if I remove 634000000 from tuning data it works fine on 674000000 but 
again not the subsequent frequencies and so on

Some applications such as vlc that can tune directly work fine (vlc 
dvb://frequency=730000000 :dvb-bandwidth=8 :program=259 etc)

Any workarounds (but merging results from scans per one frequency)?

Thanks

Hello Miroslav,

Are you absolutely sure you installed the latest code, including "make
unload" to unload the currently running modules?  I fixed this exact
regression back in June, so I would be extremely surprised if you are
really seeing this in the latest code.

I would suggest using the following commands, and then reboot:

<unplug device>
hg clone http://linuxtv.org/hg/v4l-dvb
cd v4l-dvb
make && make install && make unload
reboot
<plug in device>

Then see if it still happens.

Cheers,

Devin

Hi Devin,
I'm the person that has joined yesterday night on IRC channel to talk 
with you about this post.

During July, I've already talked with you about a problem 
(http://www.mail-archive.com/linux-media@vger.kernel.org/msg07728.html), 
but I was new and not very able to do debug and explain the problem with 
good test case.
After two months of tests and 3 adapters used (Hauppauge Nova-T, a china 
generic Intel CE9500B1 and Pinnable Hybrid Stick 320E 
EEPROM-ID=0x9567eb1a, EEPROM-hash=0xb8846b20 - only this one don't 
work), I've more information for you.

My configuration is very similar to Miroslav, Fedora 11 with kernel 
2.6.30.5-43.fc11.i686.PAE; v4l-dvb tree downloaded yesterday 
(15/09/2009) and I use scandvb to scan the channels. I've tryed your 
repository too, em28xx-vbi3, but it seems the same. The driver compile 
without problem, the system is rebooted every time I recompile it, 
modules are inserted without options and dmesg doesn't show any errors 
(http://pastebin.com/f340bf982).

Now the problem, very similar to Miroslav if MUX transmit only one 
channel; during tuning, the DVB-T stop on first MUX tuned and all MUX 
found after this one are not tuned and channels are not recognized.
During tests, I've seen that if I change the MUX order in input file for 
scandvb, I can get channels list tuned from first MUX... after more 
tuning sessions to compile the list, the problem persist during normal 
view of transmission...

If you need more info ask to me, I'll be very happy to help you; if for 
you is useful, I've saved a tuning session with usbsnoop from windows 
and I've not done this for linux, but if you need it I can do (I need 
some time to do this because I don't know where to start).

Thanks for your support,
Sebastian

Hello Sebastian,

Please do the following:

unplug the device
reboot
modprobe tuner-xc2028 debug=1
plug in the device
Make the two tuning attempts so that the failure gets logged.
Send me the full dmesg output (making sure it includes from the time
the device was connected).

Thanks,

Devin

Hi Devin,
I've done the test as you have told and the output results are at 
http://pastebin.com/f75008ea6.

The dmesg output is divided in three section:
- insert of device;
- first tuning section (only first MUX, at 474MHz, was tuned, nothing 
for 482 or 514MHz);
- second tuning section (only first MUX, at 514MHz, was tuned, nothing 
for 482 or 474MHz).

In the tuning sections I've reported input file and screen output for 
scandvb.

Thanks,
Sebastian
