Aducm3029

Hi everyone

I am a beginner of the evaluation board EVAL-AD5940ELCZ together with ADuCM3029 microcontroller units. When I was trying to use the evaluation kit on the IAR Embedded Workbench (following the example on https://wiki.analog.com/resources/eval/user-guides/eval-ad5940/tools/iar_setup_guide), it popped up the window that "Fatal error: Failed to connect to CPU Session aborted". I did not know what was going on. The following is the debug log
