I am using atmega328pb with external crystal 11.0592 MHz and seven segment and RGB LEDs. My devices works fine. But suppose I am having 300 devices and all are working fine and when I turn off and on main power then some time few devices start behaving randomly like by seeing seven segment display it pretends that device started working on 1 MHz instead of 11.0592 MHz. And some devices does not display anything but few segments of seven segment glows. And when I press the reset button then these devices start working fine. Some of these damaged devices work fine after giving power second time and some devices need to press reset button all the time after power on. Can anyone tell me what happening here?
