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

I am trying to compile for 2.6.38-8-generic kernel in Ubuntu 11.04 but so far without success. I am using the latest v4l-dvb source and driver source from http://www.turnovfree.net/~stybla/linux/v4l-dvb/lv5tdlx/. I am seeing multiple errors in rtl2832u.c. Anyone had any success?

Did you use the modified source from here http://www.medianow.com.au/data/Linux4Quad2.zip

This modified source no longer builds against the 2.6.38 kernel (in my case 2.6.38-8-generic).

It seems to be related to changes in I2C stuff in the kernel. Namely the removal of a few things like I2C_CLASS_TV_DIGITAL that were "no longer used".

CODE

/usr/src/20110512/Linux4Quad/Linux4Quad/digitalnow-quad/v4l/flexcop-i2c.c: In function 'flexcop_i2c_init':
/usr/src/20110512/Linux4Quad/Linux4Quad/digitalnow-quad/v4l/flexcop-i2c.c:253:39: error: 'I2C_CLASS_TV_DIGITAL' undeclared (first use in this function)
/usr/src/20110512/Linux4Quad/Linux4Quad/digitalnow-quad/v4l/flexcop-i2c.c:253:39: note: each undeclared identifier is reported only once for each function it appears in

I can't revert back to the older kernel as with the upgrade to ubuntu's natty release my remote/lirc only works with the newer kernel. Sure, I could go and try to figure out what the problem is with that, but it's not going to solve the problem of kernel upgrades moving forward!

Does anyone out there have any suggestions?

Thanks!

Get the source into the mainline linux kernel. It's the only sane option.
It is _much_ simpler to build the current modules from mainline now.
See http://www.linuxtv.org/wiki/index.php/How_..._Device_Drivers.
It may look a bit scary but it's really only a 'git pull' plus running the 'build.sh' script that they supply.

You may be able to get some significant help with this.
However some real details on the hardware setup and OS environment need to be supplied.
1. do a power off, wait 1 min or so, power up. Gather the output of
* uname -a
* lspci -vvxxx -s <device id>
* dmesg
2. Send this along with a polite call for help to linux-media@vger.kernel.org.
You should mention the source tarball located at http://www.medianow.com.au/data/Linux4Quad2.zip.
I've looked through this and can't find any author details, which is a pity - an AUTHOR file would help anyone trying to improve on this code.
A little cooperation with the linux kernel developers would go a long way here I think.
