Firmware Update Instructions

  1. Install the Teensy Loader program
    Download the Teensy Loader for Windows from PJRC.COM: https://www.pjrc.com/teensy/teensy.exe or for Mac: https://www.pjrc.com/teensy/teensy.dmg
    Save it to someplace convenient where you can find it, like to the desktop.
    Note: more details for using the Teensy Loader (and the Linux version) can be found here, but don’t download any firmware there:
    PJRC Teensy Loader page
  2. Download the latest The NDLR firmware and Unzip it
    Download The NDLR firmware file from the link above, being careful to select the update for your version of The NDLR (original Rev1 or Rev2 with the red base). Save it to your desktop or another convenient location where you can find it. Un-zip the .hex file from the .ZIP file (that you downloaded above) to your desktop or another convenient location where you can find it.
    1. Load the Firmware on The NDLR
      Connect The NDLR to your computer with a USB cable.
      Run the Teensy Loader program       by double clicking it.
      Click on File, then Open HEX File. Select the  .hex file you extracted above.
      Alternatively, find the .hex file with Windows File Explorer, or on the Mac, click on the Downloads icon and choose “Open in Finder”. Then drag and drop the .hex file onto the Teensy Loader program.
    2. Click the green Auto button so it is lit:
      Then use a pen or paper clip to briefly press the recessed FW button on The NDLR. It’s between the pairs of MIDI ports on the back. It takes a second or 2 to program. The NDLR will restart once it is programmed.

Troubleshooting:

      1. If you get a black screen after updating, double check that the correct firmware was downloaded. If The NDLR as a Red base, download version 3.3.x. If it’s a blue/grey base, download version 1.1.x. If you have the correct version, see no. 6.
      2. If you get a message that the file is too large, it typically indicates that the Teensy Loader program does not recognize The NDLR. First make sure you clicked on the green Auto button as shown above. You can ignore the error and try pressing the FW button on The NDLR again to see if it will work.
      3. If The NDLR is connected to a USB hub, connect it directly to the USB port on the computer while performing the firmware update.
      4. Try a different USB cable, or computer.
      5. If it still fails, the .hex file may be corrupt. Try downloading and extracting the .hex file from the ZIP file again.
      6. If you get a black screen after updating, and you are sure you used the correct firmware, try resetting The NDLR to factory Defaults using the boot menu: Remove power from The NDLR, press and hold the Menu and Shift buttons, power The NDLR and release the buttons when the boot menu appears. Press the PAD button. If asked to confirm, press the motif 2 button to confirm. Press the Panic button to exit.
