Putting the Le Potato in a car

bman1296

Hi,

I would like to put a 'Le Potato' board in my car. However, I do not want it to cycle with the ignition turning on and off - instead, I would like the board to control when it turns off (say, 24 hours after the engine being off), after detecting the ignition wire is low.

I understand completely how to do this with a raspberry pi - I use a switch to supply power to pull GLOBAL_EN to low and this trips the pi into rebooting. However, this does not exist on Le Potato. From what I have seen, when you sudo shutdown -H now, it reboots, and if you reboot it obviously reboots.

My question is if there is any functionality on the board to get it to power back up after having halted or some other means - any suggestions??

This is possible on the Amlogic SDK but upstream doesn't have suspend support yet. If you leave it in on in "halt" it will still use a watt or so which might deplete your battery after long time. Suspend is on the upstream Linux todo list.
