Hello,
So I'm trying to setup the driver files and default configurations for CS47L63 Hardware Codec. There are no build errors or flash errors but after flashing I get this error from the codec file.
<err> CS47L63: Tried writing to I2C, not supported
Am I missing something ?
This is my register configuration which I'm pushing to CS47L63, note that I got this from the audio application example directly

my execution sequence is as follows
hw_codec_init();
hw_codec_default_conf_enable();
(both the functions are taken from hw_codec header file given in audio application)
What could be the possible issue?
