DVB-C USB Tuner - TT-Connect CT2-4650 CI

Unread postby topo » Tue Mar 04, 2014 7:40 am

Hi all,
I've just received my U3 and I'm really impressed by the performance of this little PC!
I'll be using it as a HTPC and therefore wanted to connect my DVB-C receiver (TT-Connect CT2-4650 CI ). As I expected the Linux support of this device is not great out of the box but the vendor has drivers available on the website (Download: http://www.tt-downloads.de/Linux/media_build-tt-140128.tar.gz ; Install instructions: http://www.tt-downloads.de/Linux/linux_ct2-4400_ct2-4500ci_ct2-4650ci.pdf ).
I was able to get it up and running in no time on my other linux box, but I can't figure out how to get it working on my ODROID.

The make process immediately points at the .config file in "/lib/modules/3.8.13.16/build" , but "build" is a link pointing at "/data/fix500/builder/kernel-3.8/odroid-3.8.y-2014.02.11-09.16". Is this a relict from the kernel build?
Using the .config file from /boot/ i get a little further, but next I need header files such as "/lib/modules/3.8.13.16/build/include/linux/netdevice.h"

... at this point after a few hours of searching the web, installing the 3.8.13.16 linux headers and some more of my best "Linux Kung Fu" I give up...

Has anyone gotten this device or something similar working or is able to point me in the right direction on what I need to do?

Any help will be much appreciated!!!

Cheers
topo

Frist, update the kernel, run the latest kernel update script :)

Second, download the kernel sources from github.com/hardkernel/linux
branch odroid-3.8.y

Now you'll have all the sources/headers :)
Once you done that..

you can try "export KDIR=/where/you/downloaded/odroid-3.8.y"

Hi mdrjr,

that actually helped, thanks!
But I ran into the next issue after successfully compiling the drivers.
I asked the tt-connect support for help and they provided the following link for an ARM version of the sit2.o:
ftp://ftp.satelco.de/sit2-Cortex-A9.zip

Once I try to attach the CT2 to my odroid I got the following dmesg output:
[ 5.201490] DVB: registering new adapter (TT-connect CT2-4650 CI)
[ 5.202850] mousedev: PS/2 mouse device common for all mice

[ 5.301302] usb 1-3.1: dvb_usb_v2: 'TT-connect CT2-4650 CI' successfully deinitialized and disconnected


The support just replied that I shoud "...inlcude the DVB-T2 frontend by changing the .config file.".
As far as I can see all DVB frontend are included as "m"...

Any idea on what I'm supposed to change?

Thanks
topo

Hello topo, your last post on the subject is very old, but I happen to have the same problem with my DVB-T receiver on ARM. First of all, I would like to
ask you, the satelco ftp link for the ARM version of sit2.o is broken, do you happen to still have the file ? another thing, did you manage to make the 4650 work at the end ?
I am stuck at the same point as up, with DVB unable to find symbol sit2_attach().

Thanks
