How to Reimage NTP220 and NTP270

Follow these instructions to reimage your NTP220 or NTP270. You may have been told to do this due to corruption or to debug an issue. Different instructions apply to reimage a NTP200 or NTP250.

This procedure requires physical access to the appliance, a microSD card, and a laptop or computer with a microSD card reader.

To obtain a reimage image, please contact us so we can generate an image for you.

Image your microSD card

WARNING: this will destroy all data on your microSD card.

Linux Users

On a linux system you can use unzip and dd to image the microSD card. Determine which block device is the microSD card, in the examples below sdc is used.

ubuntu:/local# unzip aion_sdcard_2.16.0.zip 
Archive:  aion_sdcard_2.16.0.zip
  inflating: aion2_2.16.0_sdcard.img  
ubuntu:/local# dd if=aion2_2.16.0_sdcard.img of=/dev/sdc

Windows Users

On a windows systems, we recommend using ImageUSB from PassMark.

Unzip the compressed reimage image to obtain a .img file. WARNING: Windows defaults to hiding the file .zip extension even when it is still compressed.

Attach your microSD card reader, and open ImageUSB. Select the USB reader, Browse for the .img file, and click Write

Insert microSD card into Appliance

Install the microSD card, note that the card goes upside down, with the pin contacts on the top.

Power cycle the appliance

It is desirable to have the USB console connected, however it is not required.

Power cycle the device and observe the USB console (or LEDs). When booting from the microSD card, the device will enter reimage mode displaying the following prompt and the SYS and NTP LEDs will blink in an alternating pattern.

  ...Booting reimage image
  ...Press CMD button to start reimage...

To initiate the reimage, press the CMD button. The SYS and NTP LEDs will stop blinking and the reimage will start:

  ...Unmounting devices
  ...Unmounting uSD
  ...Reimage finished
  ...Press CMD button to reformat uSD or remove uSD to retain reimage...

Once complete, the SYS and NTP LEDs will blink in unison. You can either remove the microSD card as is (retaining the custom reimage image), or press the CMD button again to have the microSD card reformatted for generic use.

If you press the CMD button the card will be reformatted and then the device will reboot. If removed, the device will automatically reboot.

  ...Reformatting uSD for generic use
  ...Rebooting

If succesful, the device will now boot normally. Note that reimaging will reset the device to defaults.
