[solved]ADAU1701 digital audio port

I need some help to enable the audio port of the ADAU1701 please.


I set the serial out (I2S, master mode enabled, 24bits ect) and serial in registers (I2S) and the multipurpose config regs.

However I cannot see a valid signal on any of theses audio pins.


The analogue audio ins and outs are just fine, I can see that signals are routed through the dsp with a probe of an oszi.


What else can I try?!





Nachricht geändert durch rastariot, by writing the complete sequence for dsp core registers, the dsp works as it should.
