how to config gpio interrupt in imx6qsabresd?

[magicarrow98]

Hi, all

i'm used linux 14.04.5 and kernel 3.0.35-4.1.0+yocto+gbdde708.

My board is connected to the GPS PPS signal line and CSI0_DAT6.

I want to generate an interrupt when a signal is received.

what should I do?

menuconfig? board-mx6q_sabresd.c or board-mx6q_sabresd.h edit?

please, Tell me...

Sorry. I can not speak English well. I hope you understand.

Hi jun

one can look at below thread

Proper GPIO interrupt handling in iMX6 

various examples, like configuring touch interrupt can be found in

linux/../mach-mx6/board-mx6q_sabresd.c

Linux-3.0.35_4.1.0

Thanks, igor.

But I hope to have a more detailed explanation.

I want to interrupt the signal that occurs once a second, and to count the sysclk between the signals.

I downloaded the package(https://www.nxp.com/webapp/Download?colCode=L3.0.35_4.1.0_ER_SOURCE_BSP&appType=license&loca...) but it did not help. I even had it already.

Is there any other way? I want you to remember that I am a beginner.

Hi jun

for beginners suggest to start with linux tutorial:

Hi, igor

I modified the source code to use "CSI0_DAT6" as the GPIO pin.

arm/mach-mx6/board-mx6q_sabresd.h

arm/mach-mx6/board-mx6q_sabresd.c

I added the code.

Is that right?

If so, what should we do next?
