Hello guys,


I'm exploring the ARM trustzone on my IMX53QSB and I want to handle interrupts in the secure world.


Can I have an example or the steps that I have to follow to :

          - Configure an interruption as secured

          - how can I configure the flag to move to the interruption handler for example :

                              for (i=0;i<5;i++) {

                                             if (i==3) generate an interruption and go to the interruption handler


          - how to clean the flag in the handler


Thank you.
