TLV320AIC3110EVM-U: TLV320AIC3110EVM-U

Hi Sir,


Actually I am not connecting the GUI to my board, I am just using the script for ACI3110 init and Record init. I have used the script in codec. For recording mode I have connected CPU to my audio codec on fpga board and playing a sine wave. But I am not getting any sine wave samples on the i2s I have already configured the i2s in receive mode and verified the path on i2s side, from codec side I am not getting the correct sample. So, what script can I use and what are changes I can do in the script.


Thanks and Regards,
Geetha

Hi Geetha,

Could you share a block diagram of your set up? It is not clear to me what paths you have working and what path is not working. You are sending I2S samples to the codec but there is no analog sine wave output?

Also if you can include your current register configuration that will help me.

Thank you,
Jeff McPherson

Hi sir, 

you can fine the block diagram below attached what we are using,


And to send an audio data to the codec I am connecting jack pin from cpu to codec mic_in and play a sound like sine wave.
And try to receive it on i2s (sdout pin).But can not see any data on the sdout.


And below is the codec register configuration first to initialize the codec and then to initialize it in recording mode.

#include<stdio.h>
#include<stdlib.h>
#include<stdint.h>
#include "i2c_driver.h"
#include "audio_codec.h"
#define speedmode 0x63
#define CODEC_ADDRESS 0x18

Hi Geetha,

Thank you I understand the issue better now. While I study the code, can you tell me if the DOUT pin is showing any activity or toggling data? Or is it all low?

Thank you,
Jeff McPherson

No doout pin is low

sometimes after loading the bitstream with out running the elf geting some garbage samples on dout pin.

Thanks and regards,
Geetha.

This seems like a typo. Can you clarify?

Also you mentioned you based your script off the example initialization code. Do your I2S clocks match the frequencies given in the example?

Thank you,
Jeff McPherson
