Problem mini2440

Hey everybody,

i'm actually a student and i look for solution about the input/ouput of the
mini2440 (with linux). When i try to access to the registers with a memory
adress (found on datasheet) i've a segmentation fault. And i'm pretty sure
about the adress number, for exemple :

#define GPBCON (*(volatile unsigned long*) 0x56000010)

I include the librairie with all the declaration (i work in C) and i do
just a little programme with just an acess to GPBCON the compilation is
good (i've the cross compilater installed)  but the execution make a
segmentation fault.


I would be grateful if you could help me.

Google for what a "Memory Management Unit" means and how Linux makes use of
it.

thx i'm gonna try
