Hi,
I powered up a adafruit feather 32u4 while the male pins were still stuck in the pink (insulating?) foam. Now, both the green power LED and the red user controllable LED are blinking continuously.
When I try to upload a sketch I get:
Sketch uses 4104 bytes (14%) of program storage space. Maximum is 28672 bytes.
Global variables use 149 bytes of dynamic memory.
Forcing reset using 1200bps open/close on port /dev/ttyACM0
PORTS {/dev/ttyACM0, } / {} => {}
PORTS {} / {/dev/ttyACM0, } => {/dev/ttyACM0, }
Found upload port: /dev/ttyACM0

avrdude done. Thank you.
I'm running ubuntu 16 LTS, I've never uploaded to the board before.
Thanks in advance!
