Introduction

This article provides instructions needed to install the Yocto Linux SD-card image on SD card using a Linux Host workstation. The image provides full boot system including U-Boot, Linux kernel, device driver modules and example root filesystem.

Preparation steps

  • Obtain a Linux PC workstation.
  • Obtain a USB Card reader and an micro-SD Card. Any commercially available micro-SD card of 1GB (or larger) may be used for the installation.
  • Download the UCM-iMX8M-Mini Yocto Linux package from CompuLab website.
  • Unzip the package to a directory on the host workstation. From now we assume the device name is pakage_dir.
  • The Yocto Linux SD-card image file, mentioned below, can be found in the images subdirectory.
  • Plug the USB SD Card reader into the host PC. Insert the micro-SD Card into the USB Card reader. From now we assume the device name of the MMC/SD card on your Linux PC is /dev/sdX.

Installation

  • Flash the image file to the micro-SD card:
bzcat pakage_dir/images/image-ucm-imx8m-mini.sdcard.bz2 | sudo dd of=/dev/sdX bs=1M

Run Yocto Linux image

  • Insert the micro-SD card into SD socket P23 (see drawing)
  • Connect a standard USB cable (included in the kit) between your host PC and the evaluation kit micro-USB2.0 connector P13 (see drawing)
    Use a terminal emulator as described here
  • Press and hold the ALT_BOOT button (SW7) and then reset / power-on the system to force boot from SD card (see drawing). Release ALT_BOOT button after 2-3 seconds
  • The system boot into Linux.
