Astrometa DVB-stick in Amlogic

jvjlu · March 11, 2018 at 4:57 PM

Any hints to get an "Astrometa" DVB-stick (MN88473/RTL2832) to work in Amlogic (S905) devel releases (8.90.5 at the moment)? I have installed Tvheadend 4.2 and CrazyCat drivers. The stick is found and available in Tvheadend. Channels are found but none of them opens and Tvheadhend gives "Continuity counter errors". In 7.0 and 8.2 (S905) it does not work either (channels are not found or "Continuity counter errors"). Stick (all T/T2/C) works fine in RPi with Libreelec 7.0.3 or Milhouse's testbuilds (but not in 8.2.3 as well known).

@8.90.5 all you have to do is (at least my Astrometa DVB-stick works after that):

1. Install DVB Tools (from Addons > Programs)

2. SSH into yours tvbox and type (if you use tvheadend42):

systemctl stop service.tvheadend42.service

dvblast -a 0 -f 546000000 -b 8 -O 60000 -Q 60000

systemctl start service.tvheadend42.service

3. That's all, from now on you should be able to use your card without any problem

Unfortunately in latest 8.90.6 Astrometa doesn't work (probably missing/or problem with mn88473 driver)

I tried this in 8.2.3.1: I have two of these sticks, one connected to cable (DVB-C) and second one to aerial (DVB-T/T2). I gave the command twice (with -a 0 and -a 1). Now the T/T2 connected stick works but the C stick not (only RTL2832 is visible in tvheadend). The command should possibly be modified for a C network?

No, that dvblast command is only for fix "Continuity counter errors", it works for whole stick (I use it only for DVB-C on 8.90.5), it isn't any special magic thing with that dvblast command, probably there is some missing, kind of activation 'thing' in MN88473 drivers or tvheadend, dvblast just 'push it' to activate it (at last that's what I think).

Unfortunately whole stick have to be visible in tvheadend because otherwise it won't work.

I tried it with only one stick (connected to DVB-C) and it indeed worked. Thank you very much!

I have a Qodi Tap 1 box (Beelink, S905x, 2GB) and an Astrometa tuner. I cant able to use with LE8.2.3.1, after reboot it visible but cant able to tune, and after then only the SDR part staying and others are gone...any hint? Im speechless.

With dvb-fe-tools it visible and able to change mode, but cant see in tvheadend....
