Running TrustZone

Hallo,
I'm trying to run the TrustZone example from DS-5. And it's working with the RTSM-VE-A9x4. But this is just a simulation, isn't it. Because I do not have to power up DSTREAM and my board.
So I tried some more to run the example on the Xilinx Zynq board which has a ARM Cortex A9 DualCore.
BUT: If I'm using "Debug Cortex_A9_0 via DSTREAM/RVI" from Xilinx-Zynq-7000 EEP ZC702 its not working anymore. I used the connection with a hello world program before so it's defiantly the right connection. I also added
add-symbol-file "${workspace_loc:/TrustZone/normal.axf}" N:0
in execute debugger commands like it is in the RTSM version.
Nevertheless I get the following error if I want to debug the software on the ARM.
ERROR(CMD16-TAD11-NAL22):
! Failed to load "TrustZone-versatile.axf"
! Failed to write 4.872 bytes to address S:0x80000000
! General error on memory or register access.
I know the example was written for versatile express, but its also just a Cortex A9. So where is the difference? What did I forgot to change? I would be happy about some ideas.
