Part Number:PCM1789-Q1
Hi Team,
We are using DAC PCM1789-Q1 in one of our design.
We are operating the DAC in I2C Mode , While testing we observed that when try to Detect device on U-Boot ,it does not Reply (NACK on I2C).
But On Kernal same I2C address Chip reply with proper acknowledgement.
Our main purpose is to put the DAC in MUTE mode at U-Boot level itself. So if There is no -way to detect the device on U-Boot Level.
Is there any other way to force the DAC in mute Mode Till software application is up?
Attaching the Schematic for reference.
