Konstantin and i-mak,
I have a patch for you to test here:
http://linuxtv.org/hg/~awalls/new-cards/raw-rev/4c4fc0cd8e7e
You will need to extract firmware from a Windows driver for the XC3028
tuner chip. Here are the instructions:
http://www.linuxtv.org/wiki/index.php/Xceive_XC3028/XC2028#Firmware_Information
Here is the script to extrcat the firmware:
http://linuxtv.org/hg/v4l-dvb/raw-file/1da5fed5c8b2/linux/Documentation/video4linux/extract_xc3028.pl
I guessed at many parameters. No TV from the RF will work reliably
until you guess the GPIO pin to reset the XC3028 tuner chip. I guessed:
http://linuxtv.org/hg/~awalls/new-cards/rev/4c4fc0cd8e7e#l1.62
but it could be wrong.
I also guessed at how the memeory timing should be configured, the
analog audio GPIO settings, which I2C bus controls the DVB-T
demodulator, and how the DVB-T demodulation should be configured:
http://linuxtv.org/hg/~awalls/new-cards/rev/4c4fc0cd8e7e#l1.44
http://linuxtv.org/hg/~awalls/new-cards/rev/4c4fc0cd8e7e#l1.54
http://linuxtv.org/hg/~awalls/new-cards/rev/4c4fc0cd8e7e#l4.10
http://linuxtv.org/hg/~awalls/new-cards/rev/4c4fc0cd8e7e#l4.26
http://linuxtv.org/hg/~awalls/new-cards/rev/4c4fc0cd8e7e#l4.34
>From what I could read on the internet, the configuration of the GoTView
PCI DVD 3 Hybrid appeared to be very similar to the Yuan MPC718 and
PG-718.
Hopefully the patch works for at least Composite or S-Video in.
Regards,
Andy
