TI 5402 connect AC97 Codec - steven.shiou - Feb 1 9:07:00 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 ! |
