Video is present and locked but the RISC counter is stuck at the start
address. My best guess is that the CPLD is not forwarding the REQ signal
to the PCI bridge, so the BT878A can't fetch the RISC instructions.
But then there is also this persistent ADC overflow...
As for the CPLD, there is not much we can do. I count 23 GPIOs going
to that chip. And we don't know if some of these are outputs of the
CPLD, making it a bit risky to just randomly drive values on those
pins.
Is that because it might do some damage to the card, or to the host
computer, or both? Or is it just too hard to make random guesses at
what it should be doing?
If we had the original software, we could analyze what it is doing.
There is someone on ebay.com selling two of those cards and a cd
labled "Rescue Disk Version 1.14 for Linux DVR".
Ah yes, I've just found that, it seems a little pricey! There is also a
listing for an "Avermedia 4 Eyes Pro Capture Card PCI 8604" which looks
pretty much the same, but it doesn't have any software with it and
searching around for any more information on that hasn't got me anywhere.
I've just been trying to make my card work under Windows, but no luck
there either. I didn't get a driver CD with it, Windows 7 doesn't
autodetect anything for the video chips and when I tried to frig some
drivers I found earlier today for a similar looking card they did
install, but then didn't work - the not very helpful "device failed to
start" error you get in Windows. Which I guess means it's just not the
right driver.
Shame, but I think I'll just have to chalk it up to experience - it
wouldn't be my first duff purchase in the video-capture-device-for-linux
area :-)
Thanks for all your efforts.
Cheers,
Rob.
