This sounds like an error message when using the uVision simulator; is that the case? Check your memory setup to be sure the simulator knows that you have internal RAM available at 0xFE. (If you're not supposed to have RAM there, then check the configuration when you build, and STARTUP.A51, to be sure that the program doesn't think there might be memory there.)
