Help! AIC3254 on DM8168 McASP failed to work

Hi, TI Developer and Technical Suppor:

 We are woking on DM8168 with AIC3254 as audio codec.

We connect McASP2 with AIC3254 I2S singnals. And We got AIC3254 Linux 2.6.32 device driver and port to Linux 2.6.37 which version  DM8168 works with.

But when we run command "aplay test.wav" to play a song, it turns up error pcm :1682. We checked the BCLK and WCLK, no singal on it?

Would someone give us some advice?

Thanks a lot!
