Manual update

Prerequisites

Process

Linux

  • Download the latest firmware file: Changelog.

  • Plug the device to the computer

  • Open the terminal and copy/type the following commands:

    • Reset the device in upload mode: stty -F /dev/ttyACM0 1200

    • Upload the actual firmware: avrdude -p atmega32u4 -c avr109 -b 57600 -D -P /dev/ttyACM0 -U flash:w:/path/to/firmware-X.X.X.hex:i

Note

If the second command is unsuccessful you propably waited too long between the commands. After the first command the device will wait in upload mode for 5s and then restart back to normal operation.

Windows

Working on it. It should be pretty similar to the Linux process but exact commands may vary.
