ERC32 System Registers

I'm trying to calculate the CRC of the  Erc32 System Registers 
(0x01f8....).
These registers are mapped in memory through the adresses like the one 
above.

First I tried using the same technique I used to do the memory CRC, that 
was to pass the adress to my CRC calculation routine, and the length of it 
in bytes.
Since it is a 32bit registers, I passed somehing like this:

sysreg=(char*)(0x01f80000);
  crc_sys_regs=binhex_updcrc(0,sysreg, 4);

and for the second register, feeded back the value:

sysreg=(char*)(0x01f80010);
  crc_sys_regs=binhex_updcrc(crc_sys_regs,sysreg, 4);

and so on.. and so on...

But this way, when I run the program I get a trap number 9.

Also tried to do this in Assembly, by loading the content of the adress 
0x01f8000 to a register... but it gives a relocation overflow.

Maybe all this troubles are because of this registers being mapped in 
memory, but not really in memory...

Has anyone ever tried to do something like this? With success preferably?

:)
