Attempting to upload to the Flora board results in an error message, which I will post below. Afterwords the serial port which get created at /dev/ACM0 is only available for a brief window of time before disappearing. Using the Arduino IDE to upload in that brief window fixes all issues, but then I'm back to using the Arduino IDE. Let me know if more information is needed.
