Lpc2000

Hello Thiadmer

Done that in the linker file but I get an error message.

GNUARM/bin/../lib/gcc/arm-elf/4.0.2/../../../../arm-elf/bin/ld: cannot find .=0x1fc collect2: ld returned 1 exit status

Do you know why?

I have some assembler code that I can put before position
0x1FC but I don't know how to place that code there.
Can you please explain me how to do that?

Thanks.
Rui
