Bootloader Update

WARNING:
During these steps, do not disconnect USB and make sure your laptop does not shut down (check battery / use a power supply!).

You can see your current bootloader version on the display under Settings → System → System Info.

Changelog

V1.0
– Updates via USB Flash Drive are supported.

Install Bootloader 1.0 (via the display menu)

To flash Bootloader 1.0, you must first update the display firmware to at least version 1.53.

  1. Install display firmware ≥ 1.53.
  2. On the display, open: Settings → System → System Info
  3. Next to the bootloader version (e.g. 0.5) you will see a small “Update” button.
  4. Important: Before pressing it, make sure ignition is on (best: engine running).
  5. Press “Update”. The bootloader update takes about 1 second.

Note: If something goes wrong during the bootloader update, the display may need to be sent in so we can re-flash the bootloader.

Bootloader 0.6 (PC procedure / step-by-step)

This procedure installs a second bootloader into the memory area of the normal NextGen program. This second bootloader can then overwrite/update the primary bootloader.

Download Bootloader 0.6

Changelog V0.6
– No Windows driver required anymore.

How to install Bootloader 0.6

1) Extract these files

  • AK-Motion-NG-BL_0_6.srec
  • AK-Motion-NG-BL-Step1.srec

2) Start the updater

Start the AK-Motion NextGen Updater

3) Flash Step 1

  1. Click “Browse…” in the updater
  2. Select AK-Motion-NG-BL-Step1.srec
  3. On the display: Settings → System → Update and start the update

The update only takes a few seconds. After a successful update, the updater will close automatically.
The display backlight will now fade slowly (slow on/off).

4) Flash Bootloader 0.6

  1. Start the updater again
  2. Click “Browse…”
  3. Select AK-Motion-NG-BL_0_6.srec

Bootloader 0.6 is now installed. The updater will close automatically.
The backlight will switch every 5 seconds between slow and fast blinking.

Next: Install the normal NextGen update

  1. It’s recommended to unplug the USB cable briefly.
  2. Start the updater again and click “Browse…”.
  3. Select the desired NextGen update file (for example from here): NextGen Updates
  4. Wait until the updater shows: “Connecting to the target (press Update in System-Settings)”
  5. When the backlight is fast blinking, plug in the USB cable — the upload will start.

If you get an error: repeat the last step (select the NextGen update file again). It’s possible the second bootloader was active at that moment.

Done.
