Missing kernel module mn88473/general kmod questions


#23

Ah! I didnt realized that, thank you. That saves me propably lof of time playing with LXC and DVB-T, as it wouldnt help me at all…

Lets wait for next versions then, I hope, that one day I will be able work with both DVB-T and T2 on Omnia, hopefully :slight_smile:


#24

Does anyone (@Manul) with this tuner experience with official 3.10.x branch? https://repo.turris.cz/archive/omnia/3.10.7/packages/base/ seems to have compiled both modules:

kmod-dvb-mn88472_4.4.157+1-1-0a333a8e606ab056173befac424900d2-1_mvebu.ipk|2018-09-25 04:41 |4.5K
kmod-dvb-mn88473_4.4.157+1-1-0a333a8e606ab056173befac424900d2-1_mvebu.ipk|2018-09-25 04:41 |4.4K

https://gitlab.labs.nic.cz/turris/openwrt/issues/177 is still open because problems of “missing DVB Tuner” patch…


#25

Sorry, haven’t been able to follow up on this. I’ve constant stability problems with the Turris anyway and little time at the moment, but if I get around to testing, I’ll report here.


#26

Bad news. Turris OS 3.8.10, mn88473 module loaded. Used from tvheadend, Panasonic tuner scans dvb-t fine, but nothing in dvb-t2 range :frowning:

ERROR: Sorry - i couldn't get any working frequency/transponder
 Nothing to scan!!

@Pepe, do you think we could do anything with this? I can provide all assist if needed.

I checked the chip on my stick, and it is mn887473, so the correct driver is loaded…


#28

@paja @pepe could it be because some troubles witch patches?

Also, please note, that https://gitlab.labs.nic.cz/turris/openwrt/issues/177 has wrong linked patch in header (so paja marked “patch1” and “patch2” complete, but I am not sure what patches are included :slight_smile:

Finalized driver is I believe oldest one (2016-03-03), lets say “patch 0”: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/media/dvb-frontends/mn88473.c?id=7908fad99a6cc08a41c666d425df42809b34dce2

DVB-C scanning above 500MHz “patch 2” is correct (2016-12-30)

but dissapearing DVB stick “patch 1” (2016-09-17) link should be to https://pastebin.com/raw/VP2MXZdV :

I also found another patch, lets say patch 3 (2016-05-14): https://patchwork.kernel.org/patch/9094681/ which would be good to apply also.

If I would sort patches by date, it would be:

(2016-09-17) dissapearing dvb stick fix

Apart of finalize patches, maybe we need to wait for newer kernel?

Or maybe this 4.6 is mentioned, because it has at least finalizing patch from 2016-03-03?

I am really struggling to get this thing on Omnia work (I mean tune DVB-T2 programs), although it should be one of few “linux friendly” DVB-T2 stick :frowning:


#30

Now I even try to run latest TvHeadend inside LXC (Debian Stretch), but even there Ive got no DVB-T2 success :frowning: DVB-T (using also Panasonic demodulator) seems to be found…

When I tried the same stick on Odroid, it scan DVB-T2 channels just fine, so it must be somthing wrong on my Omnia :sweat:

LXC container and attach USB devices
#31

I must correct my “problems” with tuning. I even move TVH to the LXC, and @kmarty helps me a lot with investigation.

It turns out, that this is case bad antenna @building. It works fine before, when I tested it outside Omnia, but recently, propably due reconstruction I am not able to catch DVB-T2 signal strong enough (14% is tuneable on TV, but not for Astrometa).

Apologies, I dont want to confuse anyone. So, I can confirm, that Astrometa works with Turris OS 3.10.8. I did just some basic test with temporary tuning to wire from window, so I dont know if stick will dissappear after longer time period, or such.

All patches mentioned here would be good to implement anyway, but basically, this MN8873 version is fine for Linux / Omnia. (On Linux I have tested, compilation v4l media build is enough to make it work).
