I am creating a product however I do not need any input from the equipment suppliers. What it has to achieve is rock solid predictable behavior while minimizing power consumption (standby or shutdown, standby is preferred).while reacting to external events that are unpredictable. With this simple button (or pads) to control the Pi you need to have a scheme to deal with unpredictable events. I was hoping to not need a full micro controller as some are doing to wake the Pi as that seems like overkill. They are potentially tricky issues for example, if you had a power glitch and the power causes a reset you need to have a strategy to know that the Pi5 is no longer in standby when it is going to restart. While the Pi4 has a big advantage with the standby wake-up for this application, it lacks an RTC that could be critical in some applications in the future. Ideally I would like to prototype a solution before going forward. I already created a board to handle all of the above today but I need to make sure at all bases are covered.
