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

Hi magic, thanks so much for putting this script and repo together!
Even though all the information was floating around, it was quite hit-and-miss for n00bs like me who don't understand what we're doing .
I've had my Quad working a few times but was always inconsistent at getting it working again with each kernel update, so a 'wrapped' solution like this is great.

This post is really just to document an issue I had using the script (as-of today 2011/09/28 ~10am AEST.).

Following the instructions at https://bitbucket.org/themagicpudding/rtl2832_2836_2840.
I receive an error building cx23885 driver in v4l (I hope the terminology is correct?);

../../../staging/altera-stapl/altera.h: No such file or directory

.

It seems that the file altera.h is located in /media_build/linux/drivers/staging/altera-stapl/altera.h.
cx23885-cards.c includes altera.h via the relative path (../../../staging/altera-stapl/altera.h), which is "correct" relative to one of it's locations;
/media_build/linux/drivers/media/video/cx23885/cx23885-cards.c

However cx23885-cards.c is actually being built(?) from /media_build/v4l/cx23885-cards.c (I guess the sources are copied here for building?), where the relative path is invalid.

I hacked /media_build/v4l/cx23885-cards.c with an absolute path to altera.h to be safe.
This allowed everything to build without errors.

As I understand this is probably just an issue with the current cx23885 driver in v4l repo, so nothing to do with your (I guess?).
But I do wonder if something is wrong with the file structure in my build? Or something along those lines?


Unrelated to all that (I think), I eventually receive the "Hmm... distro kernel with a non-standard place for module backports detected." message.
Eventually followed by;

FATAL: Error inserting dvb_usb_rtl2832u (/lib/modules/2.6.38-11-generic/kernel/drivers/media/dvb/dvb-usb/dvb-usb-rtl2832u.ko): Invalid argument

uname -a gives;

Linux tv 2.6.38-11-generic #50-Ubuntu SMP Mon Sep 12 21:17:25 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

I haven't researched this at all yet so only mentioning for the record

Thanks again magic, and everyone else here!

Hi James,

Try the updated version like this (in a fresh check-out):

CODE

hg clone -b current https://bitbucket.org/themagicpudding/rtl2832_2836_2840 current
cd current
sudo bash rtl2832build

Hope that helps.

CODE

hg clone -b current https://bitbucket.org/themagicpudding/rtl2832_2836_2840 current
cd current
sudo bash rtl2832build

Hi magic,

I've just upgraded from 10.10 to 11.04, but cannot build the modules. I'm quite certain the reason is that I have a server version of Ubuntu 11.04 64-bit installed. So, my kernel version is 2.6.38-11-server instead of 2.6.38-11-generic. Any idea what needs to be changed to get this working?

Here's what happens when I attempt to build it.

Preparing to compile for kernel version 2.6.38

***WARNING:*** You do not have the full kernel sources installed.
This does not prevent you from building the v4l-dvb tree if you have the
kernel headers, but the full kernel source may be required in order to use
make menuconfig / xconfig / qconfig.

If you are experiencing problems building the v4l-dvb tree, please try
building against a vanilla kernel before reporting a bug.

Vanilla kernels are available at http://kernel.org.
On most distros, this will compile a newly downloaded kernel:

cp /boot/config-`uname -r` <your kernel dir>/.config
cd <your kernel dir>
make all modules_install install

Please see your distro's web site for instructions to build a new kernel.

WARNING: This is the V4L/DVB backport tree, with experimental drivers
backported to run on legacy kernels from the development tree at:
http://git.linuxtv.org/media-tree.git.
It is generally safe to use it for testing a new driver or
feature, but its usage on production environments is risky.
Don't use it in production. You've been warned.
