In the Codewarrior Online documentation a search for the word "Simulator" provides a list of topics that includes "Memory Map".

If that is what is advertised, then something needs to be corrected in the online documentation, or the simulator program, since it implies the ability to use the entire memory map including simulation of what would be external memory in some processors.

"Figure 8.15 Simulator Memory Map" from "CodeWarrior Development Tools for Motorola DSP56800 Version 5" is the referenced Online help page.

Subject: RE: [motoroladsp] move to X memory

This simulator is DSP56800 core simulator. All of our DSP56800 processors have the same core, so I am not surprised to see results that you are describing. Since the differences in peripherals and memory configuration are not primary concern for core simulator, I think developers decided to pick DSP56F805/803 memory map (these processors were the first ones we released).

When I run it under simulator, in the memory window I can see that memory is NOT written, but if I change de addres in r0 to a value under 0x0800, the value is written. It seems that the simulated DSP is the 56803 or 56805. Does somebody know wath is wrong ?
