FIQ in the secure world.

[daeyoungkim]

Hello,

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.

Hi Chip,

Thank you for the answer, and sorry for the late reply. But it seems that the fiq example does not work. Does it work?

Hi Daeyoung

I am afraid we have not such examples.
