 |
|
Searched for a working configuration for Hauppauge WinTV HVR-5500 for DVB-C from time to time and got it to run yesterday, so i just want to report it.
My configuration is kernel 3.18.1, so some paths are relative to, i used a git clone for the si2165 fronted from linuxtv.
TV-Card Description:
http://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-HVR-5500
Patch:
https://patchwork.linuxtv.org/patch/25867/
Working configuration:

First, fetch the firmware for si2165.
| Code: | cd -
mkdir get_dvb_firmware
cd get_dvb_firmware
/usr/src/linux-3.18.1-gentoo/Documentation/dvb/get_dvb_firmware si2165
sudo cp dvb-demod-si2165.fw /lib/firmware/
|
Second, fetch the actual media_build from linuxtv. Maybe you can try to patch the existing si2165.c from the local souce tree, but i can report, the following patch worked like a charm on the linuxtv repository.
The local source path is /usr/src/linux-3.18.1-gentoo/drivers/media/dvb-frontends/si2165.c.
| Code: | cd -
git clone git://linuxtv.org/media_build.git
cd media_build
./build |
Get the inofficial patch (https://patchwork.linuxtv.org/patch/25867/) and name it (here si2165-HVR-5500.patch).
| Code: | cd ~/media_build/linux
patch -p1 < si2165-HVR-5500.patch |
I copied ~media_build/v4l/si2165.c in my local kernel source tree (see above) and made a fresh kernel build.
You will have to have all necessary DVB options in .config enabled (checked/modular) for cx23885.
Because i2c is built-in kernel i had to reboot the new kernel, i could not modprobe -r all dvb_core dependend modules.
Switch the frontend to DVB-C:
| Code: | | sudo dvb-fe-tool --adapter=1 --frontend=0 --set-delsys=DVB-C |
Before:
| Code: | dmesg | grep si2165

kernel: i2c i2c-2: si2165: DVB-C is not yet supported. |
After:
| Code: | dmesg | grep si2165
kernel: i2c i2c-2: si2165: Detected Silicon Labs Si2165-D (type 7, rev 3)
kernel: i2c i2c-2: si2165: downloading firmware from file 'dvb-demod-si2165.fw' size=5768
