Jetson_Linux_R36.4.3 with external codec for i2c setting

Hi ,

We want to check for our HW design is use the I2C1_SCL/I2C1_SDA pin for codec (TLV320DAC3203).

And refer below link.

elinux.org

Jetson/L4T/peripheral/ - eLinux.org

The jetson orin NX/Nano is mapping to “Bus 7: /dev/i2c-7 => i2c@c250000” , right ?
I check the “PDD.01/PDD.02” gpio is mapping the file “Jetson_Orin_NX_and_Orin_Nano_series_Pinmux_Config_Template.xlsm”

Please help to check our enable bus is right or not ( i2c@c250000) ?

And I2S1 bus follow NX pinmux is I2S4, so we do below changes for codec bring is right ?

         /* I2S4 dai node */
           nvidia-audio-card,dai-link@79 {
                   status = "okay";
                   link-name = "ti-capture";
                   format = "i2s";
                   codec {
                           sound-dai = <&aic32x4 0>;
                           prefix = "tlv";
                   };
           };

Thank you.

I2C and I2S used are right.
