Hi Team,

                Iam working on Power Management for IMX6SL Board(ARM Architecture).Using the  command

echo mem >/sys/power/state i am entering into the suspend state. With the help of gpio_to_irq  for Watchdog reset pin and Power Key, using IRQ_EARLY_RESUME flag I am successfully able to wakeup the device.But only issue is that I am unable to get the previously stored Gnome desktop.Also Iam unable to get any image on the framebuffer when cat image on to Framebuffer.Kindly provide me any solution for the same.

Thanks & Regards,

C.Himabindu.
