OMAP3530 (BeagleBoard) interrupt question

Miguel Robertson

Hi,

I am supporting a customer who is using a BeagleBoard, and I just want to confirm something.  Is it possible to connect external interrupts to any GPIO as long as they are configured to be interrupt inputs through the firmware?

Thanks!

    For the most part yes, the GPIO module of the OMAP3 is fairly flexible and can route in an interrupt from any of the GPIO lines, though each GPIO module will share the same event from its multiple pins, you can enable specific pins on a GPIO module from the GPIO_IRQENABLE register.
