I cannot read the TZPC and TZASC registers?


I ran the ARM cotex-A9 versatile express configuration on  Fastmodel, and tried realized "smc" function.

But when I wanted to make a further progress,

I found that read the TZPC(0x100e600) and TZASC(0x100ec00) address(at the address there are 2 registers called TZPCR0SIZE and  TZC configuration )

only returned me a meaningless value(0xdfefefef) .

While according to the arm documents , the reset value of that 2 registers should be 0x200 and a value depend of the SOC configuration.

What's the problem???
