Hello,
I am trying to configure one of the general purpose I/O pins under Linux to be interrupt driven on the C6A816x (example GPO_IO4). I understand how to configure this pin as an input or output using the provided GPIO routines (gpio_set_value/gpio_get_value), but not clear how I would configure it to be interrupt driven and connect an ISR or call back routine to it. We are developing a custom driver and want to use one of the GPIO pins to generate a interrupt to our driver code.
Can you provide or point me to some example that does something like this on the integra.
Thanks,
Craig
