If the server code says that the expected min-eVOLVER port is plugged in, check that the conf.yml file has the correct port address in it (as detailed in the setup).
This happens when the micro-USB is unplugged and replugged in, but the power supply is not
Quit the server (ctrl+C), unplug the min-eVOLVER from power and micro-USB, plug the micro-USB back in, then the power supply, and restart the server
I have found this happens when the Arduino IDE program (used for putting min-eVOLVER code on the control board) Serial Monitor is open and connected to the SAMD21. Close the Serial Monitor and you will be able to start the server.
Rarely, the Arduino that runs the min-eVOLVER needs to be uploaded with its software again. Follow the Arduino Software Installation guide and upload the min-eVOLVER Arduino code onto the device.
The most common reason for this is the computer is falling asleep. Make sure your computer is set to not fall asleep.
If your computer is managed by an IT department, they will sometimes control these settings remotely. Therefore, you will set your computer to never sleep, but will come back with the setting changed. In this case, contact your IT department.
On Mac: Alternatively, you can type the command caffeinate into a terminal window and your computer will never sleep
OD is one of the most useful and most challenging aspects of eVOLVER. However the min-eVOLVER OD system is nearly the same as the main eVOLVER. Check the main OD troubleshooting page for potential causes and fixes.
