I am loading ADAU1772 program in assembly following this tutorial: Booting a SigmaDSP from a microcontroller with no C compiler .
In SigmaStudio I got project which is supposed to redirect input ( which is sound from laptop's headphones socket) directly to output, where I have connected my headphones. I just want to pass sound throughout ADAU1772 without even modyfing it. The problem is that after programming all I can hear is noise (hum). I used Saleae Logic Analyzer to follow I2C communication while programming and transmission looks exatcly the same as it is said in TxBuffer_IC_1.dat and NumBytes_IC_1.dat files. I got no idea what can be wrong, is there anything else I have to care about when I program in assembly ? Maybe I have to write some data to some extra regiters or I have to prepare ADAU1772 to programming process? I checked programming transmission byte by byte and everything looks perfect.
I rather reject that SigmaStudio project is incorrect cause I got it from a person who used Evaluation Board to program ADAU1772 and everyting was right.
