Sigma comms failled ADAU1701 / ICP3

Hello, I have an ADAU1701 card controlled by an ICP3. Sigmastudio recognizes my ICP3 and I can make my shcema but it is impossible for me to send the configuartion in my cards.
The switches are in the right position.
the cards are well connected and powered.
the drivers are well installed.
I tried several different cables.
when i use SPI to communicate with my cards i don't get an error message, but the configuration is not loaded in the cards. how to make I2C communication work?
