TBS 5922 with Openelec on Raspberry Pi B+

[BTopbas]

Hi developers! I am very grateful for your hard works. My problem is i ahve raspberry pi and i love my pi. (Ambilight and other great stuffs on pi). I have tbs 5922 usb device. And i love openelec system. I use special building image for raspberry pi. Build is use this repostory and i have issue with this. I dont know maybe other issue. Dmesg output is here

[ 10.574942] dvb-usb: found a 'TBS QBOX22 DVBS2 USB2.0' in cold state, will try to load a firmware [ 10.628633] usb 1-1.4: Direct firmware load for dvb-usb-tbsqbox-id5922.fw failed with error -2 [ 10.628660] dvb-usb: did not find the firmware file.

(-2) [ 10.628829] usbcore: registered new interface driver tbsqbox22 [ 10.636897] usbcore: registered new interface driver snd-usb-audio

whats problem? 5922 is unsupported arm system like raspberry pi?

need put device firmware dvb-usb-tbsqbox-id5922.fw to /lib/firmware

[BTopbas]

Okey. Now Openelec see device correctly. Here is dmesg:

Thank you for your quick answer :)

Here is another issue today. I install w_scan and i scan services. Scan is perfect. All channels names found and created channels.conf. But problem is Horizontal poloration is not working. Vertical channels is okey but horizantal channels give me no data error :/

Here is second edit: This device connected ubuntu. And use with kaffeine. There is no problem. All channel is stable. Working like a charm. But on the pi. Only vertical channels working horizontal channels no working. I thinking maybe usb 2.0 power issue but my raspberry pi connected 5.25v 10A power source. And model type is b+ (So usb 2.0 ports is can out more power if device need.) My brain confused.

[BTopbas]

DVB: adapter 0 frontend 0 frequency 3745000 out of range (950000..2150000). Beckend is no problem with w_scan. Found and listed all channel. But frontend not tune channel. I think this is bug?

[ljalves]

@BTopbas, Did you follow this recomendation (by @mpmc): https://github.com/ljalves/linux_media/wiki/TBS-5922-(aka-tbs-qbox22)

(If not please try it)

[BTopbas]

How can i try? Where can i add this? After make command on terminal ?

Edit: I create a options.conf in etc/modprobe.d/ and added here. Checked dmesg and manually remote not working. So i disable ir. Now i try searching channels in tvheadned.

[mpmc]

Just to add, I'm not currently using my 5922 it's in my junk cupboard, I have a DVBSky T9580 now =D. However I am willing to hook it back up if needed to help test any changes.

@BTopbas Please report back how you're getting on using the 5922 with your Pi - sounds interesting.

And @ljalves keep up the good work!

[BTopbas]

Hi all again; Today fresh installition openelec on raspberry pi. Disabled tbs5922 ir receiver. İnstall w_scan and scanning channels.

Here is w_scan scanning on bash: http://pastebin.com/NvQ9sLk1

Here is w_scan genereted channels.conf file: http://pastebin.com/7184aZtE

And i replaced pvr channels.conf to genereted channels.conf. But i want watch give me no data error most channels. A few useless channels working but most of(%90) give no data.

Here is images: https://www.facebook.com/media/set/?set=a.10205489740466478.1073741837.1340150893&type=1&l=11708a597a

[mpmc]

Have you tried something other than VDR? I'm really tempted to try my 5922 on my Pi now..

[BTopbas]

@mpmc Openelec have 2 pvr services on Raspberry. 1 VDR, 2 Tvheadend. I try tvheadend last night. But most muxes return back scan no data. Tvheadend found 10-20 useless channels. But w_scan found all channels.

[mpmc]

Is Tvheadend finding these muxes or are you manually adding them, IIRC I had to add a single mux with all the correct tuning data and Tvheadend found the rest of the muxes without issue.

I'm currently running Tvheadend on a Pi with a Technisat SkyStar USB HD and that has no issues, when I get the chance I'll try the 5922, I have a feeling it'll take hours to build though :disappointed:

[BTopbas]

I try both of them. Tvheadend finding muxes, and i adding muxes. I added but scan no data.... Here is openelec raspberry pi build with tbs 5922 driver. https://www.dropbox.com/sh/t3jtx83mcs03wpw/AACRQ4hooqTbna4lmFViVa1Ua?dl=0

File name: OpenELEC-RPi.arm-5.0RC1-fljalves-fw_fix.tar

[mpmc]

OK I've built the drivers on my Pi, but unfortunately all I'm getting is..

[    9.509551] tas2101: Unknown symbol i2c_del_mux_adapter (err 0)
[    9.517388] tas2101: Unknown symbol i2c_add_mux_adapter (err 0)

using kernel 3.12.34+ Not sure how to fix it :p

Edit:

Looks like I need to build my own kernel as the one on the RPI does not have CONFIG_I2C_MUX enabled, bah!

[mpmc]

Another update, Having built a new kernel that includes i2c_mux and built @ljalves 's tree, loading the module dvb-usb-tbsqbox22 results in a kernel oops [Null pointer dereference], This is without even having the thing attached, unfortunately I'm unable to save a copy of the error.

Luis, I'm not sure if you have a Pi, but if you do you may want to try loading the module :p it completely blows up, I used the raspberry pi's kernel source and built the modules directly on the Pi (twice) took 2-3 hours each time.

I'll have to try the Openelec image above at some point.

[saeedmou]

@BTopbas , @mpmc hi guy, i compiled my own raspian with CONFIG_I2C_MUX enabled and compile this driver, but i couldn`t load the module. here is the issue: https://github.com/ljalves/linux_media/issues/51 if you done this, plz make a installation guide. :)

[alessandro-dallatorre]

Hi guys, I have a TBS 5922SE and a Raspberry Pi 2. I'm trying to compile the linux_media drivers with no success (kernel headers not found, dependencies of a previous toolchain gcc 4.7), so I stopped and I wanted to download this raspberry pi Openelec build with tbs 5922 driver. Could anyone please help me by providing a working link to this Openelec build?

[mpmc]

@alessandro-dallatorre

I managed to get it working look at my comment on #101

[ljalves]

Closing old issue. Re-open if needed.

[mpmc]

I'd completely forgot about the TBS5922, I shall have to build again to see if it still works!

Thanks for the reminder @ljalves !
