Hi does anybody know of a program/ script/tool to visualize memory overlays (in an embedded system)??? Or even a program to analyze them? Basically a tool which works on the map file and generates some drawings! Does MS Visual have such a feature? thx bubu
lookig for a way to visualize data memory overlays

You'll need to be more specific about what you're looking for, though. What drawings would you expect to be produced by or from executable code blocks? Or, are you looking for a way to extract bitmaps that may be sitting as "resources" inside a block of memory? -- Rich Webb Norfolk, VA

I have been working with various PDP-11 systems (64 KiB user address space) with various overlay loading systems for more than a decade or used overlay loading from disk in various 8086/88 systems, but I still do not understand what you are asking. Most embedded systems have quite large code space (several KiBs) in flash and very small data space (about 1 KiB) in RAM, but in order to use overlay loading effectively, you would need something like 8-64 KiB RAM for loading the overlayed code branches into RAM for execution.
