Hi Ahmed,

Our experts are on holiday today. They will follow up with you tomorrow.

Thanks for your patience,
Jeff McPherson

Hi Jeff, 

Thank you for letting me know. 

Ahmed

Hi Ahmed,

Sure thing. They might need half a day or so to review your problem since it came in over the holiday but they will follow up with you soon.

Thanks again,
Jeff McPherson

Hi Ahmed,

Can we get the following information:

1) I2C dump of the device configuration registers in both functional case and the case where the device is not working?

2) Can we monitor the I2S signals (BCLK, WCLK) for both the 480kHz and 48kHz recording commands on a scope?

Thanks and Regards,

Lakshmi Narasimhan

Hi Ahmed,

Good to know that it is now working.

The above code lists the internal clock configurations for the device based on MCLK frequency and sampling rates. Since for 48kHz sampling rate the clock configurations are listed for 12MHz and not 12.288MHz, there was issue with 12.288MHz setting.

Thanks and Regards,

Lakshmi Narasimhan
