AverMedia A306 (cx23385, xc3028, af9013) (A577 too ?)

[wallak@free.fr]

Hello All,

I've tried to use my A306 board on my system. All the main chips are fully
supported by linux.

At this stage the CX23385 and the tuner: xc3028 seem to respond properly. But
the DVB-T chip (af9013) is silent. Nevertheless both chips are visible on the
I2C bus.

I've no full datasheet of theses chips. with exception of the af9013 where this
information is available:
http://wenku.baidu.com/view/42240f72f242336c1eb95e08.html

At this stage the CLK signal of the DVB-T chip may be missing or something is
wrong elsewhere.

If you have the datasheets... Any help will be appreciated.


Best Regards,
Wallak.
