Cortex-A9 MPCore Fastmodel Trustzone support

Note: This was originally posted on 21st March 2012 at http://forums.arm.com

I am trying to develop an trustzone application based on ARM A9MPcore Fast model. But if I tried to enable the non-secure interrupts and it is not working. Is any one able to use the A9MPCore fast model for trustzone development.


Thanks,
Gopu

    Thanks for the clarification.

    If I use the example projects, I am not getting any group1 interrupts i.e. non-secure interrupts. Even writing to GIC Distributor control register enables only secure interrupts. If I try to write 0x3 in GIC distributor control register, it got set with 0x1. But if I try the same in Cortex A8 example project, I am able to enable both non-secure and secure interrupts. But in Cortex A8, FIQ interrupts are not working.

    It is kind of trick situation and I don't know about the hardware modelling.
