Flash Instructions

The following steps will guide you through the installation of Android 9.0 on the Pico PI IMX8M Mini development kit from TechNexion.

Hardware Requirements

  • TechNexion PICO-PI IMX8MM development kit (pico-pi-imx8m-mini-4g-dev)
    • SOM with 4GB of RAM and 16GB of eMMC
    • PICO PI carrier board
    • 5 inch MIPI display (optional)
    • OV5645 MIPI camera (optional)
  • A host computer running GNU/Linux
  • Micro USB cable - serial console access
  • USB-C cable - fastboot access

Software Requirements

  • Kynetics Android 9.0 for TechNexion PICO PI iMX8MM archive, downloadable here
  • Android platform tools installed on the host computer

Installation procedure

Read the first point of the Known limitations paragraph before starting the installation procedure.

  • Unpack the Kynetics archive. The directory with the Android images will be referred as Kynetics Android images directory in this article.
  • Connect the micro USB cable to use the serial console from your host pc.
  • Connect the USB-C cable between the board and the host pc. The board will start booting: stop it at the U-Boot console pressing any button.
  • On the U-Boot console:

    => mmc partconf 1 1 1 1
    => fastboot 0

  • On the host pc console, from the Kynetics Android images directory:

    $ sudo fastboot flash bootloader u-boot-imx8mm.imx
    If this command returns an error (FAILED), change it to:
    $ sudo fastboot flash bootloader0 u-boot-imx8mm.imx

  • Reboot the board and stop it again in the U-Boot console.

  • From the u-boot console

    => env default -a
    => saveenv
    => fastboot 0

  • From the host pc, from the Kynetics Android images directory:

    $ sudo ./ -f imx8mm -e
    By default, the script flashes the partition table for the 16gb version of the PICO SOM. Use the -c X argument of the script to change this, as example:
    $ sudo ./ -f imx8mm -c 8 -e
    8GB and 28GB are available.

  • After that, run:

    $ sudo fastboot reboot
    and the board will reboot into Android.


  • Is fastboot working?
    • Yes, however the first time fastboot is used it is necessary to unlock the device, with the command fastboot flashing unlock. This will wipe the data on the device.

Known limitations

  • When the board is powered up with the micro USB cable for the serial console access connected, it is possible that U-Boot gets some input signals and stops the boot process. In this situation random characters are shown on the console, so wait a few seconds (~10) and press CTRL+C to get access to the console. You may need to reboot the board if this isn't working. This issue doesn't ususally happen when rebooting the board.
  • The Voice HAT included in the development kit is not supported in this release.
  • The HDMI output is not supported in this release.
