How to enable acces to some registers in ARM cortex a9

Note: This was originally posted on 9th November 2011 at http://forums.arm.com

Hi,

I am trying to execute the following code, which hangs when it tries to execute the second instruction:
....
mrc p15, 0, r1, c15, c0, 1
mcr p15, 0, r1, c15, c0, 1
....
Could you please tell me the reason why it hangs and how it can be fixed? Is there a way how I can enable access to the registers?

Thanks
