issues with PI SD Card .. Failing to boot... and a Heartbeat between PI and Arduino
Posted: Sat Feb 24, 2018 11:46 pm
Has anyone else seen an issue with the PI SD Card failing to boot and having to reformat the card?
I am concerned that there is no heartbeat between PI and Arduino to handle the shutdown properly.
I am going to post this here and also email Kevin. We need a heartbeat between the P{i and Arduino. This can be a GPIO dedicated to this. The PI strobes/heartbeats the line every X time. (time TBD). The Arduino monitors this line when the power button is pushed and it has sent the signal to the PI to shutdown. Once the heartbeat goes away, then it is ok to turn power off. Without this we run the risk of having the PI still up and shutting down when power is removed.
Thoughts, Concerns, etc..??
