IK Iloud mm with Adau1701 and nuvoton N79E815AT28 uP
Somebody can help to understand why my Iloud MM doesnt start properly? It has a nuvoton up, an eeprom 24c64 and ADAU1701. SDA and SCL signal are present, but at power on, it doesnt set the program and dsp parameters, than volume knob doesnt work, crossower is out of work, and sound is coming only by the tweeter.

i will try to copy the data from a working one speaker and store in a new eprom.. i hope it will work
Hello Rhodesclmk2,
First see if the DSP is reading from the EEPROM when you power up the unit. You will probably have to solder on some wire to clip a scope onto the EEPROM pins. If it is booting up then there is something else going on. There are a number of ways the audio can be stopped.
Check that the crystal is putting out a master clock.
Check the power rails.
Without a schematic it will be difficult.

Did it work for you, did you reprogram the eeprom?
