Hi,

 

I am in the prototype process, The JTAG adaptor fails to connect to the ADAU1442 on my custom board to let me use Sigma studio application to download the file /troubleshoot various serial audio inputs. The I2C address of the chipset is defined correctly in Sigma Studio environment.

The SCL and SDA have 10K pull ups on the Eval board so I followed same design practice on my hardware.  The I2C LED of adaptor starts blinking when I load the project file to the Device , no USB error message , 

 

Please, advise.


Thanks,

Semi
