The firmware apparently isn't easy to find on its own so I decided to upload my copy: https://www.sendspace.com/file/jz44eb

from dvb-firmware.

I'm on Ubuntu and I have the same problem. In which way have you added firmware to system image?

from dvb-firmware.

I just followed the documentation, don't quite remember the details. You build your own system image and sign it yourself, put said image and the signature on a SD card and let the system update. The only slightly tricky thing is that some USB sticks apparently default to ISDB instead of DVB and require a parameter to switch to the proper mode and load the correct firmware.

from dvb-firmware.

For now I don't add the firmware to the system image.
My USB dongle is recognized by the system but I have a problem with the channels. Please read all my post for any help ;-)

At first, I used this guide:
http://www.linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers

After that "dmesg" showed that system was searching for "isdbt_rio.inp" firmware. If I use that firmware from linuxtv.org, "w_scan" shows me an error, it says that my dongle can't search for TERRESTRIAL.

So, for using smsmdtv mode "DVB-T" as the default option, I forced the kernel module in this way:

echo "options smsmdtv default_mode=0" | sudo tee /etc/modprobe.d/smsmdtv.conf

After that system searches for "dvb_rio.inp", good ;-)

I used "dvb_rio.inp" from my Windows installation (md5: 146156b55ce6fc586470f28194add5a7, sha1: 48907a4749ba5fd5b4b947195c0d484e55a4c169). Now I have this output from "lsusb":

Finally I can scan and tune with a specific frequency but I can't obtain services from multiplexes.

I created a file named "frequency" with this content for doing a test:

T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy

and when I launch "dvbscan frequency" I obtain:

Unable to query frontend status.

With the utility "scan" I obtain:

WIth "dvbv5-scan frequency":

ERROR key/value without a channel group while parsing line 3 of frequency.

I tried to insert these options in /etc/modprobe.d/options:

options smsdvb force_lna_activation=1
options smsusb force_lna_activation=1
options dvb_rio force_lna_activation=1

to force Low Noise Amplifier but nothing changed.

Kaffeine is tuned with many frequency (Light green led) but can't receive channels. The same with TvHeadend that doesn't obtain services for multiplexes (but the signal is ok).

Do you have any advice? Thanks ;-)

Hi,

I have this output from tzap:

...

and I can't receive the channel (no video, no audio, no service from multiplex).

Maybe a demux problem?

(Ubuntu 14.04.1 LTS)

Thanks for any help

Ok I found a solution, we need to force mode 4, not 0.
Both are for DVB-T but with difference:

options smsmdtv default_mode=4
