User button
Input: Press the USER button
Output: Button events 1 and 0 are generated
root@imx6-tinyrexultra:~# evtest /dev/input/by-path/platform-gpio-keys*-event
Input driver version is 1.0.1
Input device ID: bus 0x19 vendor 0x1 product 0x1 version 0x100pio-keys.16-event .
Input device name: "gpio-keys.16"
Supported events:
Event type 0 (EV_SYN)
Event type 1 (EV_KEY)
Event code 116 (KEY_POWER)
Properties:
Testing ... (interrupt to exit)
Event: time 1453240251.571826, type 1 (EV_KEY), code 116 (KEY_POWER), value 1
Event: time 1453240251.571826, -------------- EV_SYN ------------
Event: time 1453240251.711820, type 1 (EV_KEY), code 116 (KEY_POWER), value 0
Event: time 1453240251.711820, -------------- EV_SYN ------------
Reset button
Input: Press the RESET button
Output: Module will execute bootloader immediately with "Reset cause: POR"
Note: Module should never freeze or hang after the reset button was pressed. Testing the operations 10 times gives a reliable result
