Hi to all! I'm trying to create a new project with µVision3 using only assembler language. I used an existing Startup.s and Target.ld files for GCC compiler, but it doesn't work if my main is "project_name.s" with a "main:" label (the error is: undefined reference to 'main'). Otherwise, if I include a "project_name.c" file with a main function, It works. Thanks to all Fabrizio
I would not call _start. I would call YOUR assembly language function (what ever its name is).
Sorry Robert, but I don't understand. Is _start directive necessary for linker, doesn't it? I have already tried to call my function name and if my function is in the same "startup.s" file all seems to work; hoterwise, if my function is located in another file, it doesn't work. Thanks
you must export the function name from the file it is in and import it where you are using it.
