Noob setup

Added by Andy Cross over 8 years ago

Hello all,

Setting up my first tvheadend backend and network scan fails every time. Is anyone able to help spot what I'm doing wrong please? Trying to follow online walkthroughs but getting stuck.

I have Tvheadend v4.0.7 running on raspberry pi 2 (OSMC) with a PCTV NanoStick T2 DVB-T2/DVB-T. I've added network and enabled the DVB-T adaptor. Using predefined muxes for Crystal Palace scan result fails on all frequencies. I've tried playing around with them and adding manually but can't get it to work. Hopefully I'm missing something obvious!

Screenshots attached. Many thanks for any help/advice, Andy

I've checked your config and it looks fine..

Could you post your dmesg? I suspect you're suffering from the same problem I had with my August T210v2 and DVBSky dual tuner. The newest firmware that's available (and included in many distros) doesn't work correctly with some devices.

If you'd rather not post your dmesg check for yourself.

Via SSH enter,

dmesg | grep si2168

You should get something like this..

[    7.897032] si2168 2-0064: Silicon Labs Si2168 successfully attached
[   35.142141] si2168 2-0064: found a 'Silicon Labs Si2168-B40'
[   35.142584] si2168 2-0064: downloading firmware from file 'dvb-demod-si2168-b40-01.fw'
[   35.751054] si2168 2-0064: firmware version: 4.0.19
.

If you're running firmware 4.0.19 you need to replace this with 4.0.4 (or 4.0.11) see whichever is better for your device; I use 4.0.4.

You can get them from here, http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/

You then do something like this.

sudo -s
cd /lib/firmware
mv dvb-demod-si2168-b40-01.fw dvb-demod-si2168-b40-01.fw.old
wget http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/Si2168-B40/4.0.4/dvb-demod-si2168-b40-01.fw
service tvheadend stop
# <-- replug the device to be sure the firmware is cleared (If you check dmesg at this point you'll see it'll complain that it can't find the firmware and in some causes will try loading a backup firmware file if it's present. -->
reboot

Once your system is up, try forcing a scan on the network. (Config -> -> DVB Inputs -> Networks -> (highlight your network) Force scan), your muxes should be working now..

HTH..

Worked a charm with v4.0.4! Spent ages trying different muxes and didn't consider a firmware error.
Thanks a million Mark for spotting the problem and for taking the time to explain the steps needed.
Very warm wishes,
Andy
