recently I bought an ultra-cheap DVB-T stick form a Chinese ebayer that is based on the rtl2832 chipset with a new tuner: the Rafael Micro R820T. It is not supported by the current dvb-usb-rtl2832 OpenPli driver, but I found a new version of the Realtek driver that adds support for this new tuner. So I ported all our enhancements on the new driver version and I made a new patch for the ETxx00 3.6.0 kernels (see dvb-usb-rtl2832_kernel_3.6.tar.gz in attachment).
It is a drop-in replacement of the current patch (there's no need to modify the recipe). This patch should also apply to older kernels (e.g. the 3.2 DMM kernel) but you may have to adapt the dvb-usb Makefile and Kconfig bits in order to apply it (not tested).
While I was working on it, I also added support for newer kernels (up to 3.8-rc4) and the current media_build experimental tree (http://git.linuxtv.org/media_build.git).
Linux PC users can use the second patch (dvb-usb-rtl2832_kernel_3.8.tar.gz) to add support for the new rtl2832 devices to their distribution kernels (through the media_build script).
A different patch is needed because in kernel 3.8 the directory structure of the media drivers has changed, so all the files have a different path.
I also implemented properly the get_frontend() ioctl on this driver, so now you can read the real tuning parameters from the tuner in Enigma 2 (Guard Interval , Code rate HP, Code rate LP, Inversion, ...). I hope this makes Ims happy ;-)

You might want to rename some enum members, else there is a compiler error:
In file included from drivers/media/dvb/dvb-usb/rtl2832u.c:7: drivers/media/dvb/dvb-usb/rtl2832u_audio.h:43: error: expected identifier before '(' tokenbecause CR_* is already defined on the ARM platform. I just appended a "_" in rtl2832u_audio.*
If someone needs the kernel module for the Galaxy Nexus and the app, I made it available here.

I have noticed that you may want to change the check for kernel >= 3.8 to kernel >= 3.7 in rtl2832u_audio.h because building with kernel 3.7 also breaks with the "unknown field ‘fe_ioctl_override’ specified in initializer" error.
Also, is there any place where this new patch is publicly available for download? By this I mean anyone can download without having to register.

Nevermind the silly question, I found it on sourceforge
I see that there is something about audio support in the driver, does anyone know if this is DAB or direct FM support and how to use it?

thanks for your feedback: I will fix the issues in a next revision of the patches.
This driver has some support for FM and DAB, but it is provided through a custom ioctl, since the dvb-usb framework provides no support for those delivery systems.
The ioctl is defined in rtl2832_audio.h:
#define FE_FM_CMD _IOWR('o', 90, struct fm_cmd_struct)
so you will need at least a customized application to be able to use it.
Also, for DAB you will need a software demodulator to really use it: AFAIK, currently there is no open source implementation available.
Maybe one day the rtl-sdr guys will come up with some news about that.

There is no need to update the OpenPli kernels again, since the fixes are necessary only for kernel 3.7 or on the ARM platform.

To ask an even sillier question: where?
Here:
http://openpli.git.s...74c8f92ef862b60
This is the first revision of the patch dvb-usb-rtl2832_kernel_3.6.tar.gz so it doesn't include the newest fixes. This time I haven't found the latest revision of the patch on sourceforge (I may have missed it though).

I am not sure, but it may be the same as the Mygica T1800B which also has this chipset, and also seems not to be included. While both are PCI cards, I think they use an onboard USB controller and show up as usb devices.
I hope this is the right place for this. Thanks for your work Ambrosa!

I just wanted to add that the Leadtek DTV2000DS PLUS has this chipset. It's ID is 0413:6f12, and it's not included in the driver as far as I can see.

This is not related for our enigma boxes as the box has no PCI slot.

Hi WTE. Thanks for your answer, but I'm afraid I don't quite follow the first bit. I know this thread (and the driver) is mainly about USB TV sticks, but these PCI cards actually use USB chipsets attached to a VIA PCI-to-USB bridge. So (assuming the PCI - USB bridge is supported in the kernel) they behave just like USB devices. At least they appear in lsusb, not lspci.
The 'solution' you refer to was posted by myself, but I haven't tried it yet I just hoped to ask the driver developers to include my device in the driver, though I should certainly see if I can get it working first. I'll report back.

The devices have a PCI express connector and act like usb device right?
When it's different can you inform which hardware model has an fixed usb connector.
The enigma2 hardware we use doesn't have PCI slot.

In any case, I first need to see if I can make the driver work with the card.
Re: RTL2832U chipset support proposal #120
Posted 4 February 2013 - 09:40
#define USB_PID_LEADTEK_WARM_4 0X6F12
after the other leadtek devices. I only guessed that this was the thing to do - I don't really know what I'm doing!
Then I compiled and installed the driver according to Ambrosa's instructions. This is what happens in dmesg after I insert the driver with modprobe:
[ 218.665051] usbcore: registered new interface driver dvb_usb_rtl2832u
[ 218.676498] IR NEC protocol handler initialized

[ 218.694192] lirc_dev: IR Remote Control driver registered, major 249
[ 218.694942] IR LIRC bridge handler initialized
It doesn't seem to detect the card, and /dev/dvb/ doesn't exist. Next I tried adding the product ID to /sys/bus/usb/drivers/dvb_usb_rtl2832u/new_id as suggested in this page but that didn't work either.
Any ideas would be greatly appreciated!
