We have a SigmaDSP (ADAU1442/ADAU1445/ADAU1446) that performs a self boot. There is a microcontroller attached to the I2C lines and also acts as a master. Is it possible to talk to the EEPROM of the DSP without using Sigma Studio?
The sequence would look something like this:
- self-boot starts
- self-boot ends
- Microcontroller updates EEPROM via I2C.
- New self-boot starts…
