[Solved] Is there a way to detect if the OS is booted?

EGM · March 2020

We have designed our own carrier board for embedded system and we would like to detect if the system is booted so we can light up a LED and cooling fan. Is there a way to do so? I did not find any useful signal on the 100-pin header.

@EGM
I think you can use DIO pins to monitor or detect if OS is booted.
For example, setting DIO pin to HIGH state when OS from the booting to the ready state, and then turn your devices on (LED and FAN).
To the same rules, turn off your device when the DIO pin state change to a LOW
BTW, you can find the carrier-board design guide here.
