Infinity ErgoDox Flashing Instructions

This wiki details how to flash the production bootloader and firmware onto a blank mk20dx256vlh7 Freescale MCU.

The Infinity ErgoDox has two different halves, each with their own firmware. Remember to flash each side with the correct firmware. The Bootloader is the same, so it's easy to correct (even without the flasher) if you flash one of the halves incorrectly.

Needed Equipment

• Computer (Flashing station)
  • Manufacturing tools installed
  • Minimum 2 USB ports
• Flasher (e.g. Bus Pirate)
• USB 2.0 (or 3.0) Micro B to A cable

Wait for flashing to complete. If flashing is successful, you will see the following things:

• Orange debug led flash, then stay lit
• LCD is on with logo, backlight is White
• The screen will show that the file flashed successfully.

/usr/local/kiibohd/<Firmware>/<Firmware>_firmware.<git rev>.dfu.bin - <git rev> - mk20dx256vlh7 was successfully flashed to 1c11:b04d

If you do not see this message, try running the command one more time. Make sure both the debug led is on and the message says 'successfully flashed'. If not, there is something wrong with either the PCB or the flashing setup.
