Other Parts Discussed in Thread: TAS3204

Hi,

I which to connect to a product that, uses a TAS3204 DSP, and reprogram it via PurePath Studio.

I have a TAS3204EVM and which to use the USB-I2C portion of the EVM to connect to the products PCB. 

Production pcb has a three pin connector (DGND, SDA, SCL), which I connect to EVM:s "GND arch",  SDA-loop, SCL-loop.

After powering up product and EVM, I open PPS Memory Tool, which says "I2C Communication Error". 

Is there any jumper settings, or so, on TAS3204EVM that I am missing? Please advice!

Thanks

Helge
