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.

Hi igor,
Thank you, but my question concerns interrupts more than the trustzone.
Have you any idea of about how to handle IRQ and FIQ.
Thank you.
