Dual TBS 5520SE Libreelec 9.0.0 Intel Generic

dave2318 · February 3, 2019 at 3:48 PM

Hi All, I've just updated to 9.0.0.

I have 2 x TBS 5520SE that i have been using with TVHeadend on an Ubuntu box for some time.

As LibreElec 9 has the TBS drivers as an option i thought i'd move my TVHeadend to the LibreElec box.

With 1 tuner it works perfectly but as soon as i plug 2 tuners in and boot i get a kernel panic.

With Ubuntu i use the TBS driver addition to media_build and 2 tuners work fine.

any thoughts?

Thanks

Dave

Have you enabled the media_build drivers? .. program add-ons > LibreELEC Module Drivers

dave2318 · February 4, 2019 at 7:40 PM

I went through each of the driver add-ons and only the TBS one resulted in my tuner being detected after a reboot. I then tried adding the second tuner and it kernel panicked

Hi,

I have TBS 6910 and the ca interfaces are not available. With 8.2.5 it`s ok. With 9.0.0 not.

Kind regards.

TBS 5520 SE single unit on raspberry pi 3, thanks for the progress on this receiver driver by the way.

I have used successfully the DVB-S and DVB-S2 (multistream) function, so far so good (4 LNBs on a DISEC)

DVB-T, works as well with my mini antenna, unfortunately I have a limited signal coming in, so can't say much on this one.

DVB-C, it seems that somehow the tuner is limited to UHF

dmesg:

using the linux DVB log I found that

So above 470 MHz I can get a scan going, but in VHF, I can't.

dmesg I see this too during the VHF scan.

usb 1-1.3: DVB: adapter 0 frontend 1 frequency 386000000 out of range (470000000..862000000)

So basically I can scan UHF channels but not the VHF (out of range)

Is there anything I can change to enable VHF on the DVB-C tuner ?

About kernel panic and.the tbs5520se, it happened to me when I powered the tuner via a raspberry usb port, when the tuner is powered by an independant power supply no more kernel panic.

Looks like this corrected version is not in my LE 9.01 I'll see if there's a more up to date driver then, thanks.

Back on the matter:

Checked the addon, looks like the last version available, the addon update procedure comes back with currently no update for this addon.

In dmesg in red, one reports that frequency 0 is out of range and the range is 174000000..862000000 unlike in the source code that sets it to 47000000 to 862000000.

then thereafter it reports the range being 470000000..862000000

so 470 Mhz to 862 Mhz

Looks like the range has been redefined somewhere and is not what is should be from the source.

OK, that would indeed explain it.

Dear crazycat

If you are going to recompile the drivers addon, can we expect any improvements in Hauppauge's drivers in old kernel 3.14?

I ask especially for Hauppauge WinTv HD dual tuner.

**crazycat** · February 14, 2019 at 6:28 PM

Hauppauge WinTv HD dual tuner support same as mainline media_tree

sorry crazycat, could it be the case also for Xbox Dvb Tuner on LE 9.0? full details in this post thx

I don't understand what actually you mean, but the tuner does not work properly when you use both tuners. It shows continuity errors, which is not the same when I use the tuner on my laptop with Ubuntu 16.

jcoenen · February 19, 2019 at 9:16 AM

The tbs5520SE related driver (inc bug fix) has been compiled and is available here. Tested this morning on DVB-C, the VHF band is now available. Now I have to figure out a way to cable up both my satellite feed and cable TV in the same location (but that's hardware). Cheers to all the developpers.

**CvH** · February 23, 2019 at 7:16 PM Official Post

it is also fixed with 9.0.1 (released soon)
