As I already posted in another similar thread, a safe and much simpler way to use sdram is: define a sdram buffer as a variable array, i.e. char bigbuffer[BUFSIZE] and then write to bigbuffer[myaddr] instead of using direct iowr. The linker automatically takes care of avoiding sdram corruption (provided you check myaddr<BUFSIZE in your code...) Cris
