[DS-5] Accessing VE RTSM peripherals

Note: This was originally posted on 17th September 2012 at http://forums.arm.com

I've downloaded an evaluation version of the DS-5 IDE to start learning some assembly, but I keep having problems trying to access peripherals.

For instance, I've tried accessing the timer0 control field using:

ldr r0, =0x1C110000 @ defined in DUI0575D VE RTSM model memory map
control .req r1
ldrb control, [r0, #8] @ load Timer1Control byte with offset 8, as defined in DDI0271

Yet I'm always presented with a Data Abort Exception.
I've tried to access the UART0 Line Control Register as well:

ldr r0, =0x1c090000
ldr r2, [r0, #0x02c]

Unfortunately I get a Data Abort Exception once again.
What am I doing wrong?

Thanks

Ha. If only I'd known (or at least had any indication of the emulated board being used).

Thank you very much for the tip, after selecting the correct RTSM everything works as expected.
