Hello,

i want to ask how i can get the DVB-T RTL2832U with the new R820T Tuner supported?

First i found this GitHub that i could compile, but it does not support the new Tuner.
https://github.com/ambrosa/DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.0

Here i found the tuner supported, but i don't know how to integrate this stuff into the driver?
http://sdr.osmocom.org/trac/wiki/rtl-sdr

Can you help?

Best Regards
Karsten

The driver is working but after some time the system crashes and does not react any more.
Just doing the simple test "rtl_test -s 3.2e6".

Hi Karsten,
this patch should fix the system crash after disconnecting the USB stick:

Re: Kernel freezing with RTL2832U+R820T

Hi Gianluca,

the crash / freezing occurs before disconnect in normal operation. So the patch will not solve this problem.

Quoted 4 lines · Karsten Malcher

Hi Gianluca,
the crash / freezing occurs before disconnect in normal operation. So the patch will not solve this problem.

Although media_build/backports allows you to build certain modules for certain older *kernels*, it doesn't mean that these modules will work tuneful within them. Therefore, I recommend the *recent* ones. Take note of last Mauro's git pull[1]. ;)

Does this mean that it should work with Kernel 3.8.5 ?

Honestly I don't know.
Regarding 3.8.y kernel series[1].
