In this case, the error appeared on a Linux when trying to upload code due to the drivers not being installed and the root permissions. language:bashĪvrdude: ser_open(): can't open device "/dev/ttyUSB0": No such file or directory You may receive an avrdude: ser_open(): can't open device error similar to the output shown below.

COM Port Not Available Windows, Mac, and Linux Users seem to be able to eventually get the board recognized by a combination of giving the computer time to finish the install ( close to 20 min), plugging the board back in multiple times, reinstalling the drivers, and/or resetting the computer multiple times ( repeat both steps). Others have had issues where the installation process hangs.īased on the customer experiences, this might be specific to the manufacturer and are usually isolated cases.
