Hi Pavel,

In our dvrrdk4.1,we use the configures as below.

tdm_slots = 32,

txnumevt = 4,

rxnumevt = 4,

DAVINCI_AUDIO_WORD_8,

The directions of Tx and Rx are right. Bit clock is 2.048MHz and frame clock is 8KHz.

But there are no data on tx and rx lines.

I really don't know why .

Maybe you can give us a good answer.Thank you in advance.

Hi Bob,

First thing to check is the pin mux.

Hi Pavel,

The pin mux are all ok.

After changing the value of mask,we can get the data from Tx and Rx lines.
