How to let gpio-keys work in ubuntu 16.04?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
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?
