I have read the Article about the Interface write back to EEPROM. I have currently a problem where I switch 2 signal sources with push button, very simple. But as it was stated that the WRITEBACK mechanism is not properly setup, I think it happens for me too. Doesn't matter which of the 2 states was selected before power off, it will always boot with the same.
Since that article is already 10 years old - is there any progress or workaround on this topic? Thanks!
That schematic is for testing purposes with the ADAU1701 MINIZ board.
