The recommended installation procedure is using a host PC with a Debian-based operating system.

Preparing the workstation

  • Install bmap-tools package if not installed
  • Obtain a USB flash drive. Any commercially available USB flash drive of 4GB (or larger) may be used for the installation.
  • Plug the USB flash drive into the host PC. From now we assume the device name of the flash drive on your Linux PC is /dev/sdX.

Preparing the Yocto Linux live image

  • Live image: imx-image-multimedia-iot-din-imx8plus.wic.bz2
  • Block map file: imx-image-multimedia-iot-din-imx8plus.wic.bmap

Preparing Installation Media

  • Flash the image file to the USB flash drive by the means of bmaptool utility:
sudo bmaptool copy ~/path/to/imx-image-multimedia-iot-din-imx8plus.wic.bz2 --bmap ~/path/to/imx-image-multimedia-iot-din-imx8plus.wic.bmap /dev/sdX
