AM3517 - wake up (sys_nirq)

Other Parts Discussed in Thread: AM3517

Hi,

I'm looking to wake up an AM3517 board through the sys_nirq line. The wakeup button is directly connected to the sys_nirq pin.

I started with following code in the board file:

        omap_mux_init_signal("sys_nirq", OMAP_WAKEUP_EN | OMAP_PIN_INPUT_PULLUP);                /* IRQn */

but canno't wake up the board after

echo mem > /sys/power/state

What do I missing ?

I checked the hardware functionaliy through a GPIO IRQ and all work fine. Can I wakeup the board through normal GPIO ? Is there any definition for wake up sources ?

cheers
