How to generate interrupt only for M4 in i.MX7D ?

[ko-hey]

Hi all

My customer use i.MX7D and plan to use GPIO interrup.
They want to generate a interrupt only for M4.
So let me confirm whether user can generate a GPIO interrupt only for M4.

We know that user can make a interrupt setting with GPIO Interrupt mask register (IMR).

Q1
In that situation, user can use Global Interrupt Controller(GIC) and Nested Vector Interrupt Controller(NVIC) for M4.
Is it correct ? 

Q2
Is there any example for test the above usage ?

Hi Ko-hey

1. right

2. for NVIC examples one can check FreeRTOS :

FreeRTOS_iMX7D_1.0.1_LINUX (REV 1.0.1)
