I2S Bidirectional communication via SAI2 in sln-local2-iot

[Blackpearl]

Hi All,

I want to configure SAI2 in sln-local2-iot which is connected to DMIC in evk board as an interface for the communication with the host processor as follows.

Pinmuxing is done as follows. 

SAI2_TX_DATA   - GPIO_AD_B0_09-Jtag TDI pin
SAI2_TX_BCLK   - GPIO_AD_B0_05-Boot pin
SAI2_TX_SYNC - GPIO_AD_B0_04-Boot pin
SAI2_RX_DATA - GPIO_AD_B0_08 - DMIC pin

I Tried to record  DMIC data from SAI1  using SLN_AMP_Write() in the host processor via SAI2 .But data is not coming  out of the TX_DATA pin. Only BCLK and FYNC is coming. I am also using Jtag for debugging.Is that making any issue ?Could you please help  me to figure out the issue?What all configuration is needed for the SAI2 to communicate with the host processor?
