TWR-AUDIO-SGTL  + TWR-K60D100M

Hi everyone,

 

I have been trying to get the I2S demo from Freescale_MQX_4_0\mqx\examples\i2s_demo working on the TWR-K60D100M + TWR-AUDIO-SGTL.

Although everything is apparently working fine (I2C, I2S), all I get from the audio output is a noise like junk while I should be getting a nice sine tone, from

the _ksai_sine_wave source.

 

I feed the source using

 

    ioctl(audio_device_file_ptr, IO_IOCTL_I2S_TX_DUMMY_ON, 0);

    while(1)

    {

   

        written_bytes = write(

            audio_device_file_ptr,

            0,

            400);

    }

 

Has anybody achieved to get the demo working on the TWR-K60D100M? (any bug fixed?)
