We are using the Analog Devices ADuC812. The board was modified per the Keil App Note 151. We are getting the following error messages ERROR 22 (NO CODE MEMORY AT ADDRESS (0707) ERROR 22 (NO CODE MEMORY AT ADDRESS (C3C3) ERROR 22 (NO CODE MEMORY AT ADDRESS (F5F5) The board is not set up to have writable code space at these addresses, so we would expect these errors if the tool is trying use them as writable code space. Any ideas on what is happening and how to solve it ?
