TI 5402 connect AC97 Codec

Started by steven.shiou February 1, 2002
We have a big problem with TI5402 connect AC97 codec . We used AD1885
(AC97 device) . We used Mcbsp0 to connect AC97 codec . Setup AC97
codec as slave mode , the DSP timeing will ok . But AC97 codec do not
have any response ! If we make AC97 codec as Master mode , that meant
BCLK(R/X) got the clock by codec 12.288Mhz , the BFSR(frame sync) need
to produce 48 Khz . But this mode timing is not ok for ac97 Timing .
Does any one have any solution about it ? please help us !
