   I use LPC1768, I modify MCU setting, the default configration is like this:   
MFlash512 (rx) : ORIGIN = 0x0, LENGTH = 0x80000 /* 512k */
This can work correctly
I modify it, make it change like this:
MFlash512 (rx) : ORIGIN = 0x0, LENGTH = 0x78000 /* 480k */
When I have changed, it can't work.
I want to know the reason and how I resolve the problem,
I see the code of the Disassembly, the program stop at the 0x00000000, it say "No Source available for g_pfnVectors()".
I want to use the top 32K of the flash to save myself data, for eample, some configration information.
