SRC4392EVM-PDK: I2C communication issues

Part Number: SRC4392EVM-PDK
Other Parts Discussed in Thread: SRC4392

Hi,

In order to evaluate the SRC4392 EVM module, i wish to communicate over I2C to initialize the registers of the SRC4392. For this, I am using PPC3. The issue is that the module does not ACK any received data.

the Module shows up as "USB-AudioEVM" on the device manager when connected over USB.

When viewing I2C with oscilloscope, the correct I2C adress (e0) is sent over I2C to the module, yet the module does send back an ACK command denying any further communications with PPC3. what might be the issue of this behavior and how to I resolve it?

Thank you.
