OMAP44XX Processor - McBSP3 Transmit Issue



Hi,

 we are working on Audio codec which uses I2C interface for configuration and TDM/I2S for audio data . we are using OMAP44X processor . The AIC3262 codec is connected to OMAP processor through MCBSP3 interface. The codec is used in master mode and mcbsp in slave mode . The problem is when we enable the MCBSP transmitter for data transfer , it is saying that the transmitter shift register is not ready . What may be the cause?
