Hello, I have keil ARM version 4.12. I develop program of generating software interrupt using “SWI 0x00” instruction in ARM. In deassembly window my source file is starting from IROM1 0x00 instead of start up file and so my Softwar Vector Address change to 0x08 to some other memory location. I go in “project->option for LPC 2300.s” and change start up file location default to IROM1[0x00] but there is no change im deassembly window. How to change the sequence of loading in memory from source file -> start upfile to start up file -> source file.
