Hi All,

I'm using a ls1012ardb and i want to make an awakening vi to gpio.

I would like to know how to carry out this action.

Thanks

Hi Joris,

In order to use GPIO as wakeup source, you need to have a driver that actually setup and request the GPIO irq. The driver needs to use device_init_wakeup() API to setup as a wakeup device, and the wakeup irq needs to use irq_set_irq_wake() API to be enabled as wakeup irq during system suspend.


Best Regards,

Zhenhua
