I've got a problem with configure USIU in MPC555. I'm using Phytec phyCORE-MPC555 module. There are two free chip selects (CS2, CS3). I'd like use one.
My configuration is following:


and i try read from addres:

#define TEST (*(volatile unsigned char *)( 0x02000000))


Unfortunately it doesn't work. Codewarrior show message box (Check Mashine Exception 0x200) when I try read this addres.
Thank you for Your help. I'm using this module in my final thesis. Could You send me any example how to configure chip select?
