Audio Dirver for the 403/405?
Hi all,
Has anybody got some working audio driver (linux) for the ML403/405 ? I know it's an ac97 codec, but I can't find anything related to the xilinx boards?
If nobody has worked on this yet, I'm in trouble. I don't know where to start, or from what ac97 driver should I base my initial development?
Any suggestion is much appreciated.
Thanks

IIRC, the old mvista 2.4 tree has an audio driver.

I am afraid it doesn't...

There are plenty of boards with an ac97 codec, but what's missing is the glue for the ML403 board, there's no pci bus in this case, opb cores instead.
I hope somebody can point me to a link of interest.
thanks

There is an opb core developed for the Xilinx University Program board, which
has a similar hardware interface to the ML403 (i.e. no PCI bridge) The XUPV2P web page with the opb_ac97 core is here:
http://www.xilinx.com/univ/xupv2p.html=20
I have a /dev/dsp driver (which I'll send to Bert directly) which limps along in 2.6.
This core has a relatively small buffer and no master access to memory, which
results in relatively poor performance, but it is a starting point.

Thanks for your input.
Can you send me the dsp driver that goes with opb_ac97? That'll be a good start for me, I appreciate your help.
thank you Steve
