Dear TIer:

WL1831 PCM clock rate configuration is 0X0200,-----HCI_VS_Write_CODEC_Config (0xFD06),

Frame-Sync Frequency configuration is 0x00001f40

But the CPU IMX6 only supply BCLK=511.363KHz,LRCK=7.990KHz.

Does the WL1831 can normal working?

Thanks!

Who is the master (i.e sourcing the bit clock) in the PCM configuration? If, WL18xx is sourcing the clock, you do not set the clock on IMX6 or codec. It is also not clear, how the WL18xx PCM port is connected? Is it connected to IMX6? or to some external audio codec?

Thanks

Hi Hari Nagalla,

IMX6 is master.AK7756 and wl1831 is slave.

Wl1831 clock and frame sync is connected with AK7756, IMX6.

Wl1831 data input and output is connected with AK7756.
