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

[wallak]

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.

You should get I2C connection to chip and after that load firmware.

Those documents are rather useless. There is few versions of Linux 
AF9015 driver around the net, which are rather near sample SDK code. Try 
to find one.

I have the A307 (product ID 0xc939) and I'd like to coordinate with you
regarding adapting your A306 support for it. If you use IRC at all, just
tell me when to be in #linuxtv, and if not, we'll keep this on-list.

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

[wallak]

A307 may be close to the A306 board. I've found the following chips: cx23385,
xc[34]?, lg3303). The demodulator is not the same, and follows the ATSC standard
(The A306 is DVB-T compatible).
Coordinating our works may be helpful, for example for the initialization and
the proper reset of the I2C chips. By email that will be OK.

Wallak.

We can take this discussion off-list whenever you are ready. The card is
in the machine on which I am typing this, so I cannot remove it and look
on the underside at this time, but IIRC there indeed is an LG chip
there. The markings on the tuner chip are covered by a thermal compound,
so I cannot read them at all, but my best guess based on the card's
specs is that it is an XC5000. I would like there to be some way to
identify the tuner programmatically, though. However, before beginning
work on the card, I would strongly prefer to verify the functionality of
its baseband inputs, and I lack the cable to attach to the baseband
connector on the card. Can you by any chance determine the pinout, so
that I could have such a cable made? Thank you.
