Hi all,
I have problem with tuning. I try two DVB-T tuner (on this device
http://dx.com/p/hd16t-android-4-0-google...ler-169876):
- MXL101 (integrated device)
- then I bought USB with AF9015 chipset + TDA 18218
My Kernel wersion is 2.6.34 and is compiled with support for MXL101 and AF9015(TDA18218).
I see frontend0 in /dev/dvb/adapter0 and also in /dev/dvb/adapter1
At web service tvheadend in configurations page I see both tuners.
But both tuners have problem with tune. Always I get this error:
[ ERROR]:dvb: "/dev/dvb/adapterX" tuning to "858,000 kHz" -- Front configuration failed -- Operation not supported on transport endpoint, frequency: 858000000
etc.
Where is the problem, what I must check?
Thanks, MG
Have you made sure the user running tvheadend has read/write access to the adapter? Usually that means making it part of the "video" group.
I also try run tvheadend as root...

You're probably missing firmware or something for the second tuner (adapter1), the other seems to be working fine.
When tvheadend try tune I found this:
[ 809.550543] af9015: too much data; cmd:41 len:59
[ 847.022245] af9015: too much data; cmd:41 len:59
[ 1027.895749] af9015: too much data; cmd:41 len:59
Sounds like the driver is broken. I would highly recommend upgrading to a less ancient kernel.
I compile different version drivers for AF9015 and error "af9015: too much data; cmd:41 len:59" is not displayed. Bud result is the same: "Front configuration failed -- Operation not supported". I also compile w_scan and today I make test with this program (maybe display more specifics informations).
I would like to use newest kernel than 2.6.34, bud I can't find newest for amlogic aml8726-m3 (with Mali-400 display driver).
What DVB API version tvheadend need? My kernel use 5.1.
w_scan works bud tvheadend no :-( It is possible import data to tvheadend from w_scan?
[root@buildroot tvheadend]# ./w_scan -c CZ

etc.
I can't remember which API it uses. You could try the stable version (3.4) and the master branch (3.9) but I suspect getting a newer kernel is the only solution.
I searched on internet for newer kernel, but for Meson3 (CPU type) newest kernel is not exist (only for Meson6, but must do a lot of editing and the result will be uncertain). I spent a lot of hours with it, but without result (bud XBMC on this device works fine). Probably I buy Raspberry Pi and it will run only tvheadend for my home network and that's it... Thank you for your support.
