I am using the SPI interface on iMX6qSabreSD platform to integrate WIFI device. I am successfully integrated SPI interface.
Now i want to use one GPIO pin on iMX6 platform to use as an interrupt.But unfortunately i am unable to find the unused GPIO pins on iMX6QSabreSD platform.
I have tried to use one GPIO pin which is being used for volume button but not succeeded.
Can any one please help me how to configure GPIO pin on iMX6qSabreSD platform and which pin can i use for GPIO.And please provide required changes need to be done in the board specific files to configure GPIO pin.
Your input is very appreciated.
Thanks in Advance.
