MAP file format

Microwalk has built-in support for loading map files, which correspond to symbol tables which map image offsets to symbol names. As the map file format varies for each compiler, Microwalk defines a very simple own format which all other formats need to be converted to.

Format

The first line consists of the image file name this MAP file belongs to.

The following lines are offset/symbol name pairs, separated by a single space.

Example:

mylibrary.dll
00000000 __ImageBase
00001010 Function1
00001ab0 Function2

Tools

Existing tools for producing Microwalk MAP files:
