I cannot read the TZPC and TZASC registers?

godlike


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???

    Hi,
    I have a similar problem, but I am working on FVP_VE Cortex-A15. I need to split dram in secure and non-secure regions since the secure sram and the secure dram are too small for my target.

    The version of Fast Models is 10.3.026 and I am using the example provided in the examples/LISA/FVP_VE.

    How can I add the TZC-400 module in the model?

    Thanks a lot in advance
