TBS6205 with 5.10.4 Identified, but nothing works. TBS6285 is perfectly fine in the same system. #228

I've compiled latest drivers from here with kernel 5.10.4 in ubuntu 20.04. I have a TBS6285 and TBS6205. When I use TBS6285 in my system everything is OK. ...

And I can use dvbv5-scan, w_scan2 and dvblast without anyproblem.

But when I install TBS6205 in the same system: ...

But nothing works. dvbv5-scan does not lock on DVBT2 frequencies, and in DVBT frequencies it times out and returns nothing. same is for w_scan2 and dvblast.

Any suggestions?

Maybe wrong TS bus config. Try add si2168_config.ts_clock_inv = 1; in tbsecp3-dvb.c @ https://github.com/tbsdtv/linux_media/blob/latest/drivers/media/pci/tbsecp3/tbsecp3-dvb.c#L1422

ahmhoseini commented 3 years ago

Added si2168_config.ts_clock_inv = 1; that to media/drivers/media/pci/tbsecp3/tbsecp3-dvb.c, (si2168_config.ts_clock_inv=0;//zc2016/07/20 for TBSECP3_BOARD_TBS6290SE in the same file, any relations?) (There is also a tbsecp3-dvb.c in media_build/linux/drivers/media/pci/tbsecp3 but I didn't modify it)

Recompiled, Deleted old modules and installed new ones. No Success! P.S: How could I get sure that this new ts_clock_inv = 1 is applied in module compile? Anywhere to check?

Look like you have very bad signal, so you not have any TS stream.

ahmhoseini commented 3 years ago

As I mentioned before, TBS6285 works fine with the same wire in the same system, and scans all frequencies with success, so it doesn't seems signal problem to me.

ahmhoseini commented 3 years ago

Do anybody here have 6205 to test with latest driver to confirm it works with this driver? Specially with T2 frequencies?

takatyan14 commented 3 years ago

I have a TBS6205, and have been using it on CentOS 8 (kernel: 4.18.0-80.11.2.el8_0.x86_64) since December 2019. It have worked well since then (It receives signal well, and the video and the audio has no noise.) Some days ago, I suddenly made up my mind to upgrade OS and driver, I installed Fedora CoreOS (kernel: 5.9.13-200.fc33.x86_64) to my machine, cloned this latest driver repository again, and built it and installed the driver. At first, It looks like it's working well, but when one tuner is being used, then I open an another tuner, and the first one loses the signal for a moment, the video and the audio have some noise. With that CentOS 8, there was no such thing.

I tried various things and I tried some revisions of the driver, so I had deleted the cloned local repository with that CentOS 8, I couldn't find out the cause. I searched similar issue here, but there aren't anything. Because it can't be helped, I gave up , I restored that CentOS 8 from my backup, and I use it. Today I found this issue, then I tried this post.

After working on reception side, and recompiling tbsdtv drivers, I could confirm TBS6205 works normally, and there is no need to change si2168_config.ts_clock_inv for this card.

The problem was, it seems my TBS6285 has a much better sensitivity, so it received all channels, but TBS6205 failed to receive in the same configuration. After working over signal reception, now both cards work well.

Sorry for disruption.
