I'm using Freescale i.MX6 DL sabresd as my platform and ubuntu 16.04 as my OS system.

I set the gpio-keys in the driver and respectively set to menu, power, volume up and volume down.

But it did not work when I push the button.

I cat /proc/bus/input/devices and I get below content.

I: Bus=0019 Vendor=0001 Product=0001 Version=0100

N: Name="mykeys"

P: Phys=gpio-keys/input0

S: Sysfs=/devices/soc0/gpio-keys/input/input3

U: Uniq=

H: Handlers=kbd event3

B: PROP=0

B: EV=3

B: KEY=800 1c0040 0 0 0

After getting this information, I tried to cat /dev/input/event3 and push the button.

Oddly, it would print some data out. So I assume that the button is work.

But why the system did not run the function that button related?

Did I miss anything?
