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.</P><P>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?</P><P>Thanks</P> Wed, 30 Mar 2022 11:38:06 GMT jens0501 2022-03-30T11:38:06Z https://community.nxp.com/t5/i-MX-Processors/i-MX-8QM-GPIO-interrupt/m-p/1436147#M188783 <P>Hello,</P><P>I am working on a project that uses the spear-mx8 board on a VAR-SP8Customboard.
