Shutdown of companion computer post flight

(David Ross) #1

Hi all,

I am fairly new to ardupilot and have just got a F450 quad with pixhawk 2.4.8 running and tuned which seemed to go pretty well. Now I have added a companion computer (RPI 2b+ with Maverick) and have a few logging issues to resolve. At least some of them I suspect are from me disconnecting the battery post flight and thus not properly shutting down the RPi.

I was just wondering how other people manage shutting down the companion computer cleanly post flight? Do you:

  • issue a shutdown command from a terminal or somehow from the GCS?
  • have a shutdown button on the drone (I guess using the I/O on the companion computer and some scripting)?
  • similar arrangement using a channel on the radio?
  • Or something else I have not thought of?

I fly with BeagleBone , RPI , BPI and Jetson NANO, some X86 CC as well and I generally don’t shutdown the system, I just unplug and let the file system recovery do his job at next reboot. I never experienced system lost because of a sudden power termination.

You can easily setup a system on ur radio to shut the system down properly. Or a push button that you hold down for 4-5 secs.
