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.

This specifies any shell prompt running on the development host
Following commands can be used to boot a fresh build of the firmware image. To simply things, there is a script in plutosdr_scripts pluto_ramboot that can do all these steps in one command.
