Hi,

 

For several days I try to generate a BCLK clock from the IMX6 for a TAS2562.

The tas2562 is in slave mode, he has is own MCLK clock internally.

The TAS2562 need a BCLK at 3MHz and WCLK at 48KHz

 

Before, I used a TAS2552 with an external MCLK. Is there a relation with the external MCLK and the BCLK generated by the IMX ?

 

My imx-tas2562.c (dai_init function) :

 

Is the function have an impact on the BCLK generation ?

 

Could you explain me how to generate my BCLK from my IMX without external MCLK ?

 

Best regards,

 

PINEAU Henri
