Toradex Easy Installer Overview

Introduction​

This article aims to give a quick overview about the Toradex Easy Installer tool.

What is the Toradex Easy Installer?​

Toradex Easy Installer (Tezi) is a Linux-based standard tool provided by Toradex. It is provided pre-installed in all newer Toradex System on Modules and contains several features and is the recommended way to flash your image. Toradex Easy Installer (or Tezi) aims to:

  • Allow users to install a selection of Operating System images into the internal flash memory of Toradex modules in an extremely simple way.
  • Allow for fully automated volume production as it allows for no-touch installation of custom images.
  • Offer configuration options for advanced users such as pre-install and post-install script execution and customized partitioning schemes.

The Toradex Easy Installer application runs completely in memory so that the complete internal flash can be erased, (re-)partitioned, formatted, or written to. The image to be flashed can be obtained over the Internet (via Ethernet), from a USB Flash Drive or an SD card.

Toradex Easy Installer Customization​

Each Easy Installer compatible image is described in a JSON image file. Toradex provides images with a proper JSON image file. Yet, depending on the use case you might need to alter the JSON image file e.g. to add an additional partition. The easiest way is to take an existing image.json file and alter it accordingly.
