Yunfei,

I have a very simple AC97 driver for the XUPV2P board, which would likely work on the ML403, using the opb_ac97 core

here: http://www.xilinx.com/univ/xupv2p.html

Currently, the timing constraints are rather tight, since the core doesn't use DMA and the buffers are relatively small.

However, I would be happy to share it with you. Are you using MVL3.0 (2.4 kernel) or MVL4.0 (2.6 kernel)?

Subject: AC'97 driver on MontaVista Linx for Xilinx ML403 board

Hi All,
I am porting a audio decoder to ML403 board, but I find there is no AC'97 driver supported. I am not familiar with the linux driver for powerpc. Could someone give me a copy of AC'97 diver which is compatible for ML403 board or PPC405.If there is none, could you tell me what could I do to alter certain copies or any suggestions.

Thanks for all your kindness.
