I have a project in uVision4 and I want to be able to use Microsoft Visual Studio to build the same project(cross compilation). So I need both projects to generate the same hex file and almost the same map file(the size of ROM and RAM must match). What could be the reason that i get different hex files? When using uVision4 the size of the code (according to the map file) is smaller than the code generated when using Visual Studio. Btw I'm compiling for ARM7. It looks to me that I have the same parameters passed to the compiler and linker as it is in the uVision project, but the output file is still larger when using Visual Studio(and using command-line options). What is the difference when using uVision, what am I missing?
