the VD-009 entry didn't work because ABUS uses 8-input multiplexers for the
four inputs. So there are 3 GPIO lines (0-2) to select the channel instead
of the two on the Phytec board.
Other things I could see from the pictures:
- You can connect an audio source to J7.
snd-bt87x will be able to capture it in analog mode.
- Any of the four bnc inputs can be routed to the cinch output.
This is controlled by U1, which is accessed via I2C.
- U14 is a video amplifier for the output.
- U1 also controls the watchdog and is able to drive the PCI reset line.
- U12 is a sync separator.
One of its outputs is connected to GPIO 15 - probably the vsync out pin.
I will try to create a patch for the card when I'm back home.
Daniel
