I'm currently working on i.MX53 with TrustZone and made a simple GPIO program using IRQ in the normal world. I want to implement the same thing, but using FIQ in the secure world. I already read the reference manual, still don't know how about that. Does anyone know how to use FIQ for user-defined buttons in the secure world? Any hint or example code would be appreciated.


Thanks you.
