I changed the OS to Carberry for a test, and now I get this message before it shuts down: Broadcast message from root@raspberrypi (Sat Apr 25 21:19:27 2015):
System halted by Carberry The system is going down for system halt NOW!
Broadcast message from root@raspberrypi (Sat Apr 25 21:19:28 2015):
System halted by Carberry The system is going down for system halt NOW! ----------- it seems that the Carberry plate tries to shut down the system. With normal linux only shuts down itself, but It succeeds with the carbian due to the shutdown deamon.
Yes, When Carberry can't get the positive ignition info from a canbus line, it requires +12V on positive ignition input in order to keep powered Raspberry Pi.
When Carberry can't get the positive ignition info from a canbus line, it seems that it does not see your car at all. Because even when I put +12V on positive ignition input, I still cannot read messages from CAN BUS. Any ideas?
Very Very Very important, Raspberry pi could not be powered by 5V micro USB port. You need to power only Carberry connecting Red and Yellow/Blue wire to +12V and Black wire to ground.
I haven't powered the raspberry, only the carberry. It was working fine, til one day, it started to shut down by itself. Still haven't found the reason
