You can put them there. You get a speed hit. You also need to make sure that the SDRAM controller is already set up before you try to use SDRAM. That means that your loader needs to initialize the controller before it loads code and data from the load source into SDRAM. stdio is something that you should expect to run slowly, so you might as well relocate it to external memory. You can do this using directives in the LDF file. Read the linker manual closely to understand how to do this. The LDF file is an extension of the linker command file used by Gnu tools, so you can get some additional insight by reading the documentation and tutorials for the Gnu linker (named "ld"). LDF adds some features for multiple processors with shared memory and for the Harvard architecture that the SHARC uses. |
