Probably you built the module for a 32 bit architecture, while Ambrosa is using a 64 bit architecture. 64 bit binaries are always bigger than 32 bit ones.

Is 07ca:3867 AVerMedia Technologies, Inc Supported?
If yes which driver should work?

[Gennar1]

07ca:3867 should be supported in the A867 driver.
You can install this kernel module:

opkg install kernel-module-dvb-usb-a867

and then please report if it works or not.

I have 32 bit machine 3.0.0-14 kernel. When doing modprobe I get

FATAL: Error inserting dvb_usb_rtl2832u (/lib/modules/3.0.0-14-generic/kernel/drivers/media/dvb/dvb-usb/dvb-usb-rtl2832u.ko): Invalid argument
walter@HTPC1010:~/DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.0/RTL2832-2.2.2_kernel-3.0.0$

make was without errors. No idea what this invalid argument means.
In dmesg i have

[ 1719.473171] dvb_usb_rtl2832u: disagrees about version of symbol dvb_usb_device_init

Any idea?

[andyblac]

it is missing some depended modules, either that or you are try to load into the wrong kernel version it was built for.

Hi Ambrosa,
Great work with the driver, my stick worked right away with VDR - except for the IR. Tried different protocols (Nec, rc5...) debug=4 etc, but I just cannot seem to get anything out from the IR. The actual device (detail below) is looking quite like http://linuxtv.org/w...ii-rev3-003.jpg and the remote is exactly like it.

But nothing from the remote.....

Any further debugging aid? Keymaps?

Also the IR seems to initiate OK:

Hi there,

i just googled for rtl2382u Kernel 3 and landed here.
I have a MSI Digivox II (w/ RTL2382u) and a running Debian Testing with Kernel 3.0.0-1.

I get a problem while "make":

Well, the headers for this kernel are installed. Do you have any suggestion how to get further?

I've an of interesting info.

Every DVB-T USB stick based on RTL2832U and tuners FC0012 or FC0013 or FC2580 or E4000 IS DAB RADIO CAPABLE
It's only a player issue (tnx Realtek for info).

Tested (by Xgaz) with my DIKOM USB DVBT stick with Windows Terratec DAB player http://ftp.terratec....tup_4.0.092.zip and original DIKOM driver.
Well .... It works !!



Ok, Enigma2 doesn't support DAB

Anyone knows a Linux DAB Player ? I wish to test my stick .... but I've found nothing about Linux (Ubuntu) and DAB ...

Hello,

Apart from opendab, there's also openmokast project: http://openmokast.org/crc-dabrms.html
It runs on linux and takes various inputs. It had been adapted to the Albrecht DAB USB stick (expired) so it could probably be adapted.

Now the question, is more "what's come out of the stick when in DAB" ? I'm not sure it is just the DAB subchannel, I heard that they send sort of a baseband sampling of the DAB signal and that everything is demodulated in software. An USB analysis from a friend had shown high bitrate transfer when in DAB mode, this could explain the thing.

Otherwise, if it is a demodulated signal, it can be either a fraction of the multiplex or the complete mux (1.5Mbits/s). Various formats exist ETI (Ensemble Transport Interface) or RDI (Receiver Data Interface).
If you have something already functional or a dump of a stream, I could try to have a look. It would be really nice to have an open receiver as no open receiver exists for DAB at the moment.

Well at least one header is not there, you might also try :http://www.dfragkopo...r/tag/rtl2832u/

Thanks, this seems to be a nice implementation of DAB on mobile devices, and looks more promising than the OpenDAB project.

Probably you are right, I doubt that Realtek bothered to develop a real DAB demodulator in hardware, due to the low market demand for this devices. The proprietary software demodulator will probably only run on x86 hardware, and probably only on Windows.
But let's wait and see, IIRC Realtek promised to release a SDK for DAB (for PC).

AFAIK, DAB mode is not supported in the Linux driver, at the moment.

Thank you.

I first thought it was supported with DTMB but it is the chinese television system not T-DMB the DAB based mobile television system :-(
At least I hoped it was possible to tune and get some raw stream.
Realtek said already last summer that they will add support for DAB in Linux but I have not seen news so far.

I heard also that it is Fraunhofer that has provided the DAB decoding suite on the PC, probably this:
http://www.iis.fraun.../pd/dab/dek.jsp

I hope that the linux implementation is not blocked by any NDA or other.
If the chip is giving the baseband signal, this could open the way to interesting application like getting the full content of the DAB mux at once, maybe even process impulse response of the channel.

I cannot wait, has anybody a hardware USB analyser to record DAB traces ? ;-)

I'm not optimist about the performance of "a platform independent fixed point C-code optimized for DSP implementation" on a 400 MHz MIPS CPU. But of course the first obstacle is the closed license of the Fraunhofer solution, so it will probably never be available on Linux.

I got it just solved, with linking all missing *.h files from /usr/src/$kernesource to the driversource dir. Worked!

Hi,
I've got an august DVB-205 V2.0 and almost given up on getting it running under Opensuse 11.4. Kernel 3.2,
dmesg:

Is there a RTL2838 patch for your kernel module?

[Gennar1]

Your device 1f4d:a803 is already supported by this driver. Moreover, I've already patched all drivers to compile and run on kernel 3.2. What's exactly your problem?

[malcolm11]

Hi Gennar1,
Sorry if I jumped nto this thread, butt as I said, I'm getting desperate.
My problem is I'm not a newbie, but this DVB stuff is really stretching me and cant make proper sense of posts on it.
I double checked and I am actually running the 3.0.4-2 kernel, Opensuse 11.4 64 bit
Followed http://linuxtv.org/w..._Device_Drivers
Compile kept crashing on 2.6 kernel, but now compiles ok on 3.0 kernel.
I know there is no realtek drivers in there, but not sure how to merge rtl2832 files and where to get the correct ones.
Do I need to install firmware, where can I find it

I had a look at your https://github.com/a...od_kernel-3.0.0 and keen to try it.
Do I need to do anything extra like edit the makefile.

[Gennar1]

I'm not sure about this (that's not my repo, it is mantained by Ambrosa), but you can give it a try. Even if the instructions are for Ubuntu, they should work with Opensuse as well.

If not, given there is some interest, I will try to give you a general method working with any distribution/kernel.

[malcolm11]

Thank Gennar1,
Still not sure if I need a fw file

[Gennar1]

No, no firmware file is needed.
