[linux-dvb] Need Help with PCTV 452e (USB DVB-S2 device with STB0899)

[linux-dvb] Need Help with PCTV 452e (USB DVB-S2 device with STB0899)

[Jens Krehbiel-Gräther]

Hi!

After two defective devices I got now a working one from pinnacle 
support (I tested it in Windows and it works fine).

But under Linux I could not get a positive scan or channel-lock. Could 
please anyone tell me what I am doing wrong? I read the list and 
searched the list archive and did everything described here, but my 
device isn't working.

I followed the instructions of the wiki about this device:

hg clone http://www.jusst.de/hg/multiproto
wget -O pctv452e.patch http://www.linuxtv.org/pipermail/linux-dvb/attachments/20080125/b9e1d749/attachment-0001.patch

insmod dvb-usb-pctv452e.ko
# in case some insmod complains about unresolved symbols: 
modprobe firmware_class


I can compile multiproto and install the modules. The device ist 
recognized when plugged in:

syslog tells this:

I downloaded the dvb-apps:

I downloaded the patched scan:
wget http://jusst.de/manu/scan.tar.bz2

I downloaded the patched szap:
wget http://abraham.manu.googlepages.com/szap.c

I updated version.h and frontend.h in the include path with the version 
of multiproto. Everything compiles fine, but finally nothing works.

When I scan for channels, this is the output after some time:

scanning dvb-s/Astra-19.2E

In the syslog I got this entry several times:

So what can I do to make things work? What am I doing wrong since other 
people here report successfull working devices?
I have several lines of this in the syslog:

Feb 21 17:06:56 dev kernel: lnbp22_set_voltage: 2 (18V=1 13V=0)

Is this OK or ist this an error (set_voltage 2)?? If 0=13V and 1=18V 
what is 2??

Hmm, I discovered that there's in an issue in pctv452e.c line 426 which should be:
  { STB0899_I2CRPT        , 0x58 },
In the patch there's 0x5c as value which doesn't work for me.

Could you please try this and report if it works for you too.

Great, that was the trick, now scanning and szap work fine.

Thanks for that hint!

You're welcome.

BTW: do you receive broken streams  (symbol rate 22000 or 27500)?
Currently I get a loss of about 1 TS packet every second or even more (with both symbol rates).
And there is exactly one TS packet missing (I diffed a TS hexdump).
If it were the USB controller that drops packets it would be a loss of 5 consecutive TS packets. (940 bytes iso frame size)

Thanks for testing,
 Dominik

I will test it soon and give a report.

I have to correct that statement (I didn't record the whole TS): 
The loss is exactly one USB frame (5 consecutive TS packets in this case)
which happens about every 1000 TS packets (200 USB frames)

I'll do further testings with different frame sizes the next days...

Is it really isochronous transfer that the device really uses in it's
default mode ? I guess many vendors prefer bulk transfers for the
default transfer mode ?

Hi,

The attached pctv452e.c works for me without frame drops in DVB-S and DVB-S2.

The problem seems to be  wrong initial config parameter set in init_s1_demod table.
I copied this table from the mantis 1041 and it seems to be working now.
(I should probably check the USB logs and use these values.)
The first tuning after powerup/init fails quite often for me but the folllowings are fine
even switching from DVB-S to DVB-S2 works like a charm.

There's a bulk pipe but it's only used for setup/control afaik.


Happy testing,
Dominik


BTW: why is the mantis development in a separate HG repo?
 I merged the mantis driver to the multiproto repo and can use the
 mantis-1041 and pctv452e simultanously :)

Nice to know it works great. Should i pull the patch into the multiproto 
tree to
make it easier, since it works as expected ?

Also, can you test DVB-S2, a 30MSPS stream whether it works as expected ?
(in case you have access to such a transponder ?)

Currently, i have mixed results, so some amount of further test results 
would
be quite nice

I do expect quite some changes to the mantis bridge and have been touching
very much mantis/bridge specific changes in that tree. Additionally, i 
plan to push
out multiproto prior to mantis, so both in one tree will make it a bit 
messy.

That would be nice, I'll prepare a patch next days (which also includes the TT-connect S2-3600 patch from André).

And I would also like to add a sample tuning application since this seems to be the most common
issue when trying to get DVB-S2 running

which satellite/transponder has got such a rate? 
I can only receive 19.2E and 13.0E but both don't have high rate dvb-s2 transponders :(
