    Wei,

    You cannot use GIO 31 for interrupt from WLAN module. In DM36x you can use only GIO-0 to GIO-16 for interrupts. If you are using EMAC for ethernet, then you'll be left with only GIO-0 for interrupt.

    Hope this answers your query.

    Hi All,

    I have registered an interrupt for the GIO pin 0 with the irq number 44. When i try to run it i am getting an error as below

    "No IRQF_TRIGGER set_type function for IRQ 44 (AINTC)"

    The following is the part of the code :

        status = request_irq(irq_num, &gpio_irq_handler,IRQF_TRIGGER_RISING, "gpio_test", NULL);

    I have changed the values of the the trigger type referring to both interrupt.h as well as ioport.h but with no help.

    Could anyone please suggest what could be the problem
