How to generate interrupt INT7 in GPIO1?

Markon — Mon, 05 Dec 2016 12:17:01 GMT

I need individual interrupt from pad GPIO_7. I configured registers connected with GPIO, IOMUXC - similar as in Interrupts with GPIO1 INT0-7 , and GIC registers. When I have interrupt handler bounded with IRQ 98, it works. When I have interrupt handler bounded with IRQ 90, it doesn't work. According to i.MX 6Dual/6Quad Applications
Processor Reference Manual, GPIO_7, ARM processor should receive also individual interrupt from GPIO_7.

How to configure iMX6Q to reveive individual interrupt, IRQ 90 ?

Please refer chapter 3.2.4 "Interrupt Source Code Structure" of i.MX Linux Reference Manual.

Have a great day,
Victor

I'm not good in Linux. I work on FreeRTOS and I'm looking for solution connected close to hardware.

Hello,

Also, the following may be helpful.

How do I configure the INT0-INT7 interrupt request of GPIO1 source?
