I have a question about the No DAC Config (GPIO5-8 not jumpered) and bringing up a new DAC. I have EVB Rev 1.1 with the Cirrus Logic codec.
I set No DAC config mode but can't read the Cirrus DAC using the CP21xxCustomizationUtility.exe. I tried writing the values from the factory set OTP config 0 (Cirrus codec config) to RAM, observed a Reset take place but still no DAC access. The CP2114 spec states in section 8.2 that DAC configuration text files can be written to RAM and tested. However, if the tool can not read from the DAC, can it still write it?
I tried setting the boot config to 0 as well so the audio configuration string parameters would still get loaded for the I2C and audio codec but, no luck there either.
The goal is to modify the DAC registers in the No DAC Config mode. We'll also need to connect another codec with a different I2C address and was hoping to write the Audio Configuration String + DAC configuration string to RAM to get it up. Maybe we'll have to create an OTP config and set it as the boot index first?
I'm sure I'm missing something and was hoping for some guidance.
