The currently loaded firmware version number can be determined:

  • in the navXUI when the “Board Info” button is pressed
  • via the software libraries
  • via the “Currently-loaded Firmware Version” tab of the firmware tool described below

Requirements

  • "Classic" navX-MXP: navX-MXP Circuit Board (rev. 3.3 or higher)
  • "Generation 2" navX-MXP: navX2-MXP Circuit Board (rev. 4.1 or higher)
  • PC with USB 2.0 port running Windows 7 or greater.
  • Mini-USB Cable

Updating the Firmware

  • Within that directory, select the sub-directory for the matching Generation:
Generation Sub-directory name
Classic classic_navX
Generation 2 gen2_navX2
  • Within the sub-directory matching your board's generation, the firmware file will be named using this pattern:
navx-mxp_X.Y.ZZZ.hex

(X = Major Version Number Y = Minor Version Number Z = Revision NUmber)

  1. Connect a USB-mini cable from a Windows PC to the navX-MXP circuit board.
  2. From your Start Menu, select “Kauai Labs” and then “navX-MXP” and click on the run the navXFirmwareUpdater, and follow the directions included in the program.
