Embedded C code for lpc2148 works on simulator not on hardware

 A simple embedded c code was written to display hello world code on terminal window. At first a char pointer was created to store hello world. Checked UOLSR register to see if UOTHR was empty .if it was then the data was loaded into UOTHR using pointer. After running the code I got the required output on the uart1 window(view->serialwindow->#uart1).

But when I tried to dump the code on lpc2148 kit using flash magic and then tried to execute it...the terminal window showed strange characters on screen.
