Hi,
I realized that we did not have a quick start guide posted to the evaluation board page for the AD6655. Please find it attached and let me know if you still have trouble with operating the AD6655 evaluation board after reading through this document and following the desribed procedure. I apologize that this was not already available. I will be submitting this document to our Tech Doc team to have this added to the evaluation board page.
When you get the error message in SPIController (product config file doesn't match the product) just click 'Ignore' and let SPIController open. You should then be able to open the AD6655 config file by going to File -> Open Cfg File.
Regards,
Jonathan
