I've been working with the A256 for a few years now, but we can't find them in stock anywhere, so we decided to try the DP512 in it's place. All of the documentation that I could find showed that this should be a drop in replacement. However, when I go to program the parts, the programmer says that it can't program block $C000. I am using Metrowerks version 3.1.
Anything obvious that I'm missing? Is the 512 a drop in replacement for the 256?
