UCM-iMX8M-Mini: Debian Linux: Manual Installation: SD card

Introduction

This article provides instructions needed to install the Debian 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 Debian Linux package from CompuLab website.
• Unzip the package to a directory on the host workstation.
• The Debian 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.

• Flash the image file to the micro-SD card:

bzcat ~/path/to/ucm-imx8m-mini-debian-linux/images/debian-ucm-imx8m-mini.sdcard.bz2 | sudo dd of=/dev/sdX bs=1M

Run Debian Linux image
