Rebooting Pluto/M2k

There are few different use cases, and methods to locally (USB/Serial), or remotely (USB/Network) to reboot a Pluto/M2k.

Pluto/M2k was designed never to have to be rebooted - but software bugs happen. Before you reboot things - try to ask yourself “why”, what went wrong, how do I reproduce, and how can I file a bug report that will help someone debug.
