Example Project uploaded but doesn't work with battery power

I tried the Edison_Pedometer_with_OLED project using Arduino IDE 1.6.4.

It works the first time after upload.
But after power off and on again, it will no longer work, whether with USB power or battery.

It seems that the example program does not run automatically after boot up.

Please help!
