Hi Don,
You cannot access all memory address in WinCE6.0. It has been divided into
Kernel mode and User mode.
You may not access hardwares directly via an application of User mode in
WinCE6.0. Try to move them to Kernel mode or access through a driver.

I hope it is useful ^_^

I am trying to Port the above code to Windows CE 6.0.
I used to compile the above code in Platform Builder 5.0 as a C program.
I
don't notice a way to write a C program in Visual Studio 2005 with the
Windows CE 6.0 add on. Is there a way? When I was using Platform Builder
I
had decided that I did not need a driver in the form of a DLL and just
wrote
directly to the PCI Bus with the above code in a console app using
Platform
Builder 5.0. The exe built in Platform Builder 5.0 does not run under
Windows CE 6.0. Is this what I should expect, exes built for 5.0 will not
run on 6.0? Do I really need to write a proper driver DLL to talk to the
PCI
bus?
