DigitalNow Quad DVB-T Tuner Card and Linux, it is working Options

[renura]

Hi Guys,

We have a couple of reports from Linux users about having the Quad DVB-T tuner card working under Linux.

So, if any one who has got the card and wants to try under Linux, please let us know how it goes.

You will need to download this

Hiya

Flunky had asked for some sample lspci output - have attached along with lsusb for the same box

This is an AMD64 Ubuntu 10.04.2 machine.

Cheers,
Hugh

I can confirm I have this card working in Ubuntu 11.04. You may also be able to get this working using the instructions from the post #40 on this page:
http://ubuntuforums.org/showthread.php?t=1678094&page=4

But i went my own way with the newer realtek drivers.

My system:

CODE

uname -a
Linux HTPC 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

What I did:

First needed to grab the latest V4L drivers:
http://www.linuxtv.org/wiki/index.php/How_..._Device_Drivers

Following instructions from the above link (and knowing that build-essentials contains a couple of the required packages), I grabbed what other I needed for my ubunutu installation.


I did:

CODE

sudo apt-get install build-essential git patch patchutils libproc-processtable-perl

Next I downloaded a built the drivers. Building is not really necessary here but it is included in the main script and only takes a few minutes.

from me home directory

CODE

cd ~/

I did:

CODE

git clone git://linuxtv.org/media_build.git
cd media_build/
./build.sh

Next i grabbed the latest realtek drivers from here:
https://www.turnovfree.net/~stybla/linux/v4l-dvb/lv5tdlx/

CODE

wget --no-check-certificate https://www.turnovfree.net/~stybla/linux/v4l-dvb/lv5tdlx/20110614_RTL2832_2836_2840_LINUX+rc.zip
unzip 20110614_RTL2832_2836_2840_LINUX+rc.zip

You might need to

CODE

sudo apt-get install unzip

if you don't have it.

Now you need to add these drivers to the V4L drivers.

Copy the newly unzipped files across (you will need to change the path if your realtek drivers are different).

CODE

cp ~/20110614_RTL2832_2836_2840_LINUX+rc/*.* ~/media_build/linux/drivers/media/dvb/dvb-usb/

And next I patched the v4l drivers using steps 5b and bc from the readme in the realtek drivers.

(Readme is

CODE

gedit 20110614_RTL2832_2836_2840_LINUX+rc/Doc/readme.txt

)

CODE

gedit ~/media_build/linux/drivers/media/dvb/dvb-usb/Makefile

Add these two lines at the end of Makefile:

CODE

dvb-usb-rtl2832u-objs = demod_rtl2832.o    dvbt_demod_base.o dvbt_nim_base.o foundation.o math_mpi.o nim_rtl2832_mxl5007t.o nim_rtl2832_fc2580.o nim_rtl2832_mt2266.o rtl2832u.o rtl2832u_fe.o rtl2832u_io.o tuner_mxl5007t.o tuner_fc2580.o tuner_mt2266.o tuner_tua9001.o nim_rtl2832_tua9001.o tuner_fc0012.o nim_rtl2832_fc0012.o demod_rtl2836.o dtmb_demod_base.o dtmb_nim_base.o nim_rtl2836_fc2580.o nim_rtl2836_mxl5007t.o tuner_e4000.o nim_rtl2832_e4000.o tuner_mt2063.o demod_rtl2840.o tuner_max3543.o nim_rtl2832_mt2063.o nim_rtl2832_max3543.o nim_rtl2840_mt2063.o nim_rtl2840_max3543.o qam_demod_base.o qam_nim_base.o tuner_tda18272.o nim_rtl2832_tda18272.o rtl2832u_ioctl.o nim_rtl2832_fc0013.o tuner_fc0013.o
obj-$(CONFIG_DVB_USB_RTL2832U) += dvb-usb-rtl2832u.o

next

CODE

gedit ~/media_build/linux/drivers/media/dvb/dvb-usb/Kconfig

And add these lines to the end:

CODE

config DVB_USB_RTL2832U
    tristate "Realtek RTL2832U DVB-T USB2.0 support"
    depends on DVB_USB
    help
      Realtek RTL2832U DVB-T driver.

Next, compile and install!

CODE

cd media_build/
make distclean
make
sudo make install

However, mine didn't compile! I got a lot of errors... but there is another driver file to try in the current build...

CODE

cp ~/media_build/linux/drivers/media/dvb/dvb-usb/rtl2832u.c ~/media_build/linux/drivers/media/dvb/dvb-usb/rtl2832u.c.orig

cp ~/media_build/linux/drivers/media/dvb/dvb-usb/rtl2832u.c.bak ~/media_build/linux/drivers/media/dvb/dvb-usb/rtl2832u.c

Now

CODE

make
sudo make install

Reboot and the card should work (no remote though)

Thanks for inspiring me HTPC_Freak.

In case anyone out there is interested in building the module for 2.6.38-10, apply the attached patch in the .../20110614_RTL2832_2836_2840_LINUX+rc directory after the unzip step in HTPC_Freak's howto:

CODE

cd <where-you-unzipped-20110614_RTL2832_2836_2840_LINUX+rc.zip>
patch < 2.6.38-10-generic.unified.diff

The patch is here:  2.6.38_10_generic.unified.diff ( 10.23K ) Number of downloads: 11


I have patched the code to successfully build and for the driver to work with the 2.6.38-10-generic kernel (the one I'm currently using on my mythbuntu box).

From memory when I checked out the diff of that rtl2832u.c.bak file it had just had all the remote control stuff commented/hacked out of it. I've done some looking through the LinuxTV git repo and there has been a bunch of reshuffling where the remote control stuff is so I guess this .bak version of the file was to get around that to get the module to build.

I have gone through the revision history of the files to piece together what has been changed and updated the driver code to look for the remote control stuff (just some restructuring of data structures) in the right place.

So in theory this should mean the remote will work OK with my patched version (assuming it ever worked?!). I don't use the Quad's remote myself though so can't confirm this.

Oh - and you might find it necessary to run

CODE

make menuconfig

and select the rtl2832u module after you've edited the Kconfig as in HTPC_Freak's post.

If someone notices the remote isn't working with this, let me know.

Hope that helps!
