Hello everyone,
So I've got the head unit connected and everything and it works great. However, about 70% of the time, the device keeps starting then turning off just after starting the car. I could get it to boot properly by disconnecting and reconnecting the 5V input from the pi itself, this works every time, but it's annoying. Did anyone else have this problem?
I suspect that when starting the car, the voltage from the battery would drop for about a second due to taking so much power to start the engine, this could drop the voltage so low for the 5V converter that it would not supply enough power for the pi, the pi would recognize this and would keep restarting until the power is disconnected then reconnected. I think it also doesn't help that I've configured it to enable the turbo for the cpu on startup (I don't remember exactly but it might be something like 2.5GHz for the startup).
I'm thinking of getting a super cap or something to supply the pi with enough initial power but I don't want to go through all that trouble if there is a better solution, or even if the initial power isn't the problem.
Thanks in advance!
