ASRC clocks

[john9]

Hello Guys,

I created two different versions of a driver for akm codec. I used SSI2 (i2s-master mode) and the AUDMUX5 as the main interface of my board and the codec (slave).

My first driver  (based on SSI) was working correctly, it was playing audio on my speaker. But, on my second driver, I extended my previous driver and added the ASRC. The DAI LINK was showing correctly but when I play a wav file (tinyplay <wav> or tinyplay <wav> -d1) I did not hear any sound on my speaker. Then, I found out that only the STDO (imx6) has a data coming out, no BICK and FCK clocks.

I would like to know how to enable the clock for ASRC as a master mode?.

Btw, I am using android 5.x.

Regards,

John

Hello John,

    The issue should be errors on bit clock setting, so please check the bit clock setting of ASRC according to Table 15-14 Bit Clock Definitions in Reference Manual of I.MX6Q(IMX6DQRM.pdf, page 671)!
