Hello,

Thank you for letting me post in your forum. I'm a linux newbie so please forgive me if i make mistakes.

I'm an happy owner of a Raspberry Pi, and I would like to try my DVB-T usb stick.
I've tried to compile Ambrosa's drivers but unfortunatly we don't have kernel headers package yet for the Debian RPI, so I had to compile the whole kernel (though for a first try).
I've tried this one https://github.com/t...ernel-3.0.0.git and it's the same.
My kernel is 3.1.9 so I took 3.0.0 library. Same if I try 3.2.0.

I managed to do it with some copies & adapts. Compile is ok and the stick is mounted (see log below).
My problem is that it cannot see channels. I think it comes from the fact that bandwidth=0, but channel is ok when I check logs in debug mode.
I've tried tvheadend, but it sees nothing. w-scan idem. Kaffeine cannot see the stick.

If I could force default bandwidth to 8Mhz I think it would solve the problem. How can I do that ?

Thanks in advance and thank you for your drivers.

Kind regards
Marc

I put back my yesterday's image, install manualy kernel.ipk, module, modprobe and it seems, now it searching dvb-t programs (16 programs - include radio). And works

Nice

+rtl2832_set_parameters frequency = 482000000 , bandwidth = 0

Tuning parameters are OK. bandwidth=0 means 8MHz in the DVBv3 API, so that's fine with kernels older than 3.3.
The problem is that, for some reason, the driver can't get a lock on the given frequency.

Thank you !

In fact it came from the fact that the RPi doesn't give enough power. I have to use a powered usb hub.
I also have to double check if it works on both usb ports because I've just finished my test and on one port it didn't work.

Thank you again.

Can i have a ipk file for the 8000 please? I'll test it with the NOXON USB DAB stick.

[ims]

I will try build it for 8000.

[Anzo]

I will try build it for 8000.

Thanks in advance, I would appreciate that very much. I have also a Noxon stick.

[ims]

Try it.

Install it, then in telnet/ssh run:

modprobe dvb-usb-rtl2832

and restart GUI.
set tuner in menu and then search services


If it will be work, then for running after reboot: in telnet/ssh run

echo "dvb-usb-rtl2832" > /etc/modules-load.d/dvb-usb-rtl2832.conf

and then

update-modules

Note: If will be problem with mounting hdd's/usb devices after reboot ( as it is on my dm800se), rename dvb-usb-rtl2832.conf to z.conf and run again:

update-modules

Installing didn't get me far, sorry...

[ims]

do you have updated your 3.0 ? kernel-module-dvb-usb and kernel-module-rc-core are installable ( tried on 800se and today's night build).
try opkg update/upgrade before...

Edited by ims, 10 June 2012 - 19:07.

[Anzo]

still on openpli 2.1 because of the fawlty openpli 3

[ims]

oh... this patch is for 3.0 Alpha only... 2.1 has old kernel.

[Anzo]

you're telling me to take the risk of installing the openpli 3.0 image on my DM8000? Tricky

[ims]

No, will be patient, when it will be beta! ... I thought, that you are trying alpha.

Ok, guys, I use Ubuntu 10.04 and kernel 3.0.0-21-generic. When I follow the directions in https://github.com/a...d_kernel-3.0.0/ I get

user@host:folder$ sudo make
make -C /usr/src/linux-headers-`uname -r` SUBDIRS= modules
make[1]: Entering directory `/usr/src/linux-headers-3.0.0-21-generic'
  CHK	 include/linux/version.h
  CHK	 include/generated/utsrelease.h
make[2]: *** No rule to make target `kernel/bounds.c', needed by `kernel/bounds.s'.  Stop.
make[1]: *** [prepare0] Error 2
make[1]: Leaving directory `/usr/src/linux-headers-3.0.0-21-generic'
make: *** [default] Error 2

Any suggestions on how to fix that? I tried with kernel 2.6.x and the same problem appears. I have the headers, but this file kernel/bounds.c is missing from the directory. But should it be there in first place? Those are headers after all?

Any help would be much appreciated!

[martinmarinov]

Ok, got it working on Ubuntu, now time to make it working on Android

I have successfully compiled the module for Android but when I do

# insmod dvb-usb-rtl2832u.ko
insmod: init_module 'dvb-usb-rtl2832u.ko' failed (No such file or directory)

And dmesg says

dvb_usb_rtl2832u: Unknown symbol dvb_usb_device_init (err 0)
dvb_usb_rtl2832u: Unknown symbol dvb_usb_device_exit (err 0)

Hi Gennar1,

I've temporary replaced the .conf opkg feed files of OpenPLi with the VIX ones. And after an opkg update, I've found a driver for RTL2832 that I managed to install via Telnet.
And... Everything works fine ! My two USB tuners are working without any problem

Too bad this driver is not in the OpenPLi feed !
Anyway, thanks for this tip !

-cyb-

Hi -cyb-

How did you do that?

[Anzo]

test with OE2

[erkkisdt]

I guess the driver (0ccd:00d3) is not yet available for OpenPLi-3.0-beta-vuuno as I get

root@vuuno:~# modprobe dvb-usb-rtl2832
FATAL: Module dvb_usb_rtl2832 not found.

and

root@vuuno:~# opkg install kernel-module-dvb-usb-rtl2832
Unknown package 'kernel-module-dvb-usb-rtl2832'.
Collected errors:
* opkg_install_cmd: Cannot install package kernel-module-dvb-usb-rtl2832.

My Terratec Cinergy TStick RC would be happy to do work for me, if the driver would be there.

On X-Trend ET6000, the Twintech UT30(RTL2832u) is very easy to make it work..
Just searching the name of the circuit in the packet list, install it,
After tuner set up with the correct frequency steps, 8Mhz for instance; scan and that's it.
It works flowless on both SD ans HD with DD+(E-aC3)
For the tuner installation be finished, I had only to switch off the box so that the tuner be recognized.
Only caveart, there is still the nasty bug when closing down the Box on HD+EAC3 chanel. When it start again, the picture trough HDMI is all corrupted...
No idea about to solve this issue???
