I2S Sport DMA Rx ERROR

HI all,

I'm using the AD1938 on an ADSP-SC584 custom board. I'm trying to test the audio passthrough example with the AD1938 on behalf the AD1979 and AD1962a on the EZ-KIT.

I've configured all the AD1938 register via SPI. All ADC an DAC are configured as master and I use the master clock in as PLL clock source.

The ADC othe AD1938 is connected to SPORT0A and the DAC to SPORT0B

the serial port configuration is the same as on the ez-kit for ADC_DAC_Audioplayback project.

So when I enable the ADC, I have an error in ADC sport callback, when I print the callback event error I have code 2 antd it mean this :

/*! Data overflow primary channel when SPORT is operating in Rx mode */
ADI_SPORT_HW_ERR_PRIMARY_CHNL_OVERFLOW = 2,

Does someone can help me to find the source of this error

Best regards,

Namory
