Problem when I using UART and I2S simultaneously on C5535 eZdsp

Hi,

i merged the two examples (aic3204+uart) from spectrumdigital test code and board support library (CCS 4.2) for the eZdsp5535.

I would like to send the samples from aic3204 left channel to UART.

I noticed that when I call the function EZDSP5535_I2S_init(); UART stop working. I monitored the TX pin with a oscilloscope and there is no activity.

In the exactly moment I call  EZDSP5535_I2S_init(), TX goes to zero. If I don't call EZDSP5535_I2S_init(), UART works OK, but off course I don' get samples from AIC3204.

aic3204_loop_linein.c

/* Initialize I2S */

EZDSP5535_I2S_init();

/* Play Loop for 5 seconds */
for ( sec = 0 ; sec < 5 ; sec++ )
{
  for ( msec = 0 ; msec < 1000 ; msec++ )
  {
  for ( sample = 0 ; sample < 48 ; sample++ )
 {
   /* Read 16-bit left channel Data */
   EZDSP5535_I2S_readLeft(&data1);

   EVM5515_UART_putChar(data1 & 0xFF);
   EVM5515_UART_putChar(data1 >> 8);
  }

}

Thanks for your help!
