Have you downloaded an application to ADuC's flash?
No, this is a fresh microcontroller , not programmed yet. I am not able to access it through UART. can u plz tell wat check inorder to make sure uC is alive..?
Have you tried powering the unit on?
See www.analog.com/.../ADUC831.pdf page 63, In-Circuit Serial Download Access I hope that helps
