Hi, My boot code copys all code from Flash into faster SRAM for execution on startup. How can I relocate all of the code to ensure the jumps work. I've read App note 138 about relocating functions but doing it this way would mean that I have to relocate each C file (there's 19 in this project) and the project would become unmantainable as you have to specify a store and execution address which will change with each code update. Is it possible to relocate an entire code space? Any suggestions greatly appreciated. Thanks Mark.
