TLV320AIC3007: TLV320aic3007 codec interface with i2S lines

6375419

Part Number: TLV320AIC3007

Hi,

I am trying to interface TLV320aic3007 codec with i2S interface on atmel chip.I am using 4.9.151 kernel version.Please let me know tlv320aic3007 codec will work with default driver provided by source or it require any driver changes for working with i2s interface.

Thanks & Regrads,

Prasanth

Hello,

The upstreamed drivers you'll find in the github repositories will provide the base ALSA commands to record/play audio with the CODEC. You can select the audio interface modes of operation, including I2S, through the driver as well. You will likely have to modify parts of the device tree and HAL to connect the ATMEL resources to the driver commands.

Hi ,

Thank you for response ,I interfaced tlv320aic3007(i2c/i2s) to my soc(a5d27).when i am playing sound with aplay command i am getting below error.Please have a look on below detaills.

Hello,

Unfortunately we are not Linux experts and will need to focus our support around the TLV320AIC device that we know well. Can you confirm you can read/write registers in the CODEC, and if so, please send us the register dump and also an image of the I2S audio serial lines as well if possible while trying to record.
