Hi. I am experiencing the same problem as Kevin -- InitAIC10 routine will loop infinitely at IfRxRDY0. My jumper setting is slightly different from Kevin's :- W12 open -- disable DAA feature W14 1-2 -- use DSK's CLKOUT W18 2-3 -- to DVDB 5.0V W19 1-2 -- to AVDB 5.0V W35,36 open -- disable DAA feature W61 2-3 -- to DVDD1 3.3V Note:- Beside the supplies from DSK, my setup does not have any external power supplies(5V,12V) Appreciate greatly if anyone can offer insight to the above problem. Thanks & regards, Doreen P.S. Jean, did you encounter the above problem when you try the tone generation with AIC10EVM? --- In c54x@y..., "Kevin Howson" <kevin@k...> wrote: > Hi, > > We are trying to get the VC5402 DSK up and running with the AIC10EVM Codec > daughterboard but are having a number of problems as detailed below.
