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 ).
As a last resort, the Arduino
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.
The most common reason for this is the computer is falling asleep. Make sure your computer is set to not fall asleep.
As a last resort, the Arduino
Rarely, the Arduino that runs the min-eVOLVER needs to be uploaded with its software again. Follow the Arduino Software Installation and upload the min-eVOLVER Arduino onto the device.
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 for potential causes and fixes.
