Prof7500 and TBS6981 using S2api5

[jimlas53]

I am working on both the prof7500 USB DVB and the Turbosight TBS6981 DVB PCIe card. I am using the S2-Liplianin driver files for the Prof7500, and a modified version for the TBS card. Right now only the prof7500 is responding, the TBS module does not load as it should. I don't know if the make install for one unit is killing the other one.
I'm in need of help from someone very familiar with the S2 API stuff.
Thanks!

 

[updatelee]

try just coping the ko's required over

the TBS isnt supported in the default v4l tree or igor's ?

 

[jimlas53]

I have 3 sets of files: from Liplianin, from TBS, and now fromlinuxtv/ v4l-dvb. The TBS driver files are not in the distribution at v4l-dvb. I assume they were added by the manufacturer, which means they might show up at a later date in one of the other packages, but who knows?
I'm working through the make/config system to understand how this all works, so I can build the needed modules without overwriting something important. The last time I did compiles and builds it was on a CP/M system. I guess that kind of dates me...

Interestingly, there is no driver source code, rather two .o files are included.

UDL, maybe the fastest course would be to make sure the STV0900 files are compiled in the TBS package? I haven't looked to see what files are needed for the Prof7500, but I recall you mentioned them in your blog.

I wish Turbosight had submitted their stuff to Igor so it would appear in the tree.

 

[updatelee]

where did you get the TBS src from ? I'll take a look at it.

http://www.buydvb.net/download2/TBS6981/linux-s2api-tbs6981_v1.92.2.rar

I didn't know if the board would allow URL...

Modinfo shows the kernel module is proprietary to Turbosight. Maybe I answered my own question..
However the system is not loading this module, so I borked something.
I know you're very familiar with the Prof7500 driver files - if you stripped your .config down to only the needed files, can you list them? I'd like to work with something known here

Thanks for the help!

 

[crackt]

are you bulding the prof module after the tbs module ? if they both use the stv900 frontend driver one build is over writing the other. can you load the tbs module without the prof installed in the pc ?

updatelee if tbs is only providing object files then i doubt there is source available. i havent used my tbs tuner lately but it may just need a card id patched in. i thought tbs products were similar to prof products.

crackt out,.

Looking at dmesg, appeard the prof 7500 is being detected and initialized OK.
The TBS card is having some issues:

I only selected what seemed obvious for the TBS6981 card and built the TB S driver. Something is missing and was not caught as a dependency?
updatelee, have you had a look at the TBS files?

 

[jimlas53]

A little more tinkering with menuconfig got the TBS card initialized OK as well:

OK, now that both devices appear to be communicating with the kernel, I would like to check out the functionality of the prof7500 and the TBS card. I have one 90cm sat dish, ku band, with a ku lnbf at 10750 MHz, a SG motor, and good S,Q on Galaxy 19 and SES-1, plus most other birds. I assume I can only connect to one lnb port on one card at a time. I have a Geosat receiver and know the dish is pointed correctly. I had hoped to eventually use Mythtv to incorporate all media, but that is for later.
What is the best way to wring these cards out?

 

[updatelee]

man why wouldnt they just release the src... grr. I cant even compile this, my kernel is too new... I'll try another night in vmware with an older kernel.

what I would first try using the Prof 7500 driver from the TBS build, if you want to make sure your using the latest code (there doesnt apear to be too much different, I checked) then manually make patch;s from the two src tree's and then apply them to the TBS folder. would prob be easier then the other way around.

 

[updatelee]

Do you only have the two receivers ? the TBS and the Prof ? is the lnb linear only ? do you have any more lnb/dish's ?

 

[jimlas53]

I got started in this adventure by buying a Geosatpro dish, lnb, and DSR200 receiver. My intent has been to incorporate the sat into Mythtv so I could have a "convenient" mix of media.
My assumption was that I could use the receiver to help get the dish set up and peaked, find some viewable channels and have a known working system before adding the TBS card. Up to this point I have, on a couple of occasions, actually got the tuner to lock on one channel. I have assumed compatability between the TBS card and the rest of the system. Same with the Prof7500.
So, when it comes to satellite systems, I don't even know what I don't know!
So I am VERY appreciative for help!

 

[updatelee]

thats an excellent way to get setup. The geosat will prob be alot easier to setup and get you comfortable with fta. I bet once you get mythtv setup and used to it you'll love it though ! hehe

 

[jimlas53]

OK now, keeping in mind I'm totally NOOB here: Trying to tune one channel, SES-1@101W, 12060 H 26700, which is History E. although it scans as enc test 11 or somesuch with the DSR200.

The TBS card is at /dev/dvb/adapter1/frontend0
The Prof7500 is at /dev/dvb/adapter2/frontend0
The sat cable is connected to Prof7500
So I set up the command with tune-s2:

tune-s2 12060 H 26700 -adapter 2 -lnb STANDARD
LNB: low: 10750 high: 0 switch: 0
opening: /dev/dvb/adapter2/frontend0
LOW band

Frequency: 12060 H 26700
22khz: OFF
Modulation: QPSK
FEC: AUTO
Inversion: AUTO
Rolloff: AUTO

>>> tuning failed!!!
Closing frontend ...

Am I doing something wrong here?

 

[jimlas53]

Running szap-s2:
szap-s2 -c channels.conf -S 0 "HEST" -l 10750,10750,11700 -a1
I see this on the terminal:
status 1e | signal df08 | snr ea00 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
I assume this is a good thing!
dmesg shows:

[ 9807.196032] stv0900_get_rf_level: RFLevel = -39

[ 9809.388036] DEMOD LOCK OK

So it looks like the prof7500 is able to tune and lock.
Can I use VLC to see if I'm getting video? If so, how?

its starting to sound like the tbs cards are using a customized stv900 module that has no public source code. ive not had much time to invest in this scenario but i have the hardware to reproduce it. im going to setup my htpc with the same tuners and ill post my findings.

I think the TBS card is cx23885-based:

[ 13.397264] cx23885[0]: cx23885 based dvb card

I'm trying to scan:

scan-s2 -a1 -f0 -o zap -l10750,10750,0 -c ses1-101w

There is something scan-s2 doesn't like about the syntax, but I haven't found it!

 

[jimlas53]

All right, I found a working syntax, but the tuning failed:

So both devices appear to lock, but fail scan-s2.
What does this mean, and will I ever have a working Mythtv setup?

updatelee, I ran tune-s2, and the TBS card appears to tune just fine:

[updatelee]

in post #13 you said the TBS is adapter1 and the Prof is adapter2

did you reverse them ?
