Hello,
I am working on a project that uses the spear-mx8 board on a VAR-SP8Customboard. I have Linux running on the Cortex A cores and I am able to run some bare metal C code on the cortex M4 co-processors using the MCUXpresso SDK.
Now I want to configure a GPIO pin as input and use this pin to trigger an interrupt in the M4. I have seen examples of interrupts with timers, but I am unable to find some example or even some good documentation. Has anyone already used a GPIO as an interrupt on the cortex M4 or is there some documentation about this?
Thanks
