I have backlight driver that exelent works on ColibriPXA320 806Mhz v2.0B. I rewrite PDD layer this driver using ToradexCeLibraries v1.6. In library.
I use pwm module for control backlight and gpio module for initializing LCD. Driver good works on VF61, but after board goes to sleep and followed by awakening(43 SODIMM by default), board does’n responds, Async is not connected, backlight off. In driver’s log I see that Power Manager sends IOCTL request IOCTL_POWER_SET with D4 to the driver and then log ends. Please help me.
