Unable to get Part ID and Booloader version.

I downloaded the following codes from the prototype-to-hardware page: /media/uploads/bjsrlu/source_codes.bmp

I am able to get the "Synchronize" message after I type ? but I try to run the command to get the part ID by typing the letter J or K to get the bootloader version, I am seeing garbage character. /media/uploads/bjsrlu/screen_capture.bmp

Can anybody tell me why?

If you are interested in building one and tell me what's wrong. Here is my Gerber file: /media/uploads/bjsrlu/lpc1768_minimun_hardware.zip
