Mastering Mender

Secure and Automated Updates for Embedded Linux

Objectives

  • Understand the challenges of updating embedded Linux devices
  • Automate the update process for embedded Linux devices using Mender
  • Set up and configure a Mender server
  • Deploy updates to devices using Mender, and monitor their progress.
  • Use advanced Mender features such as rollback, A/B updates, and update channels to improve update reliability and flexibility.
  • Integrate Mender with cloud providers such as AWS and Azure for OTA updates, and use delta updates to reduce update sizes and bandwidth usage.
Labs are conducted on target boards, that can be:
    Dual Cortex/A7-based "STM32MP15-DISCO" boards from STMicroelectronics.
    Quad Cortex/A9-based "SabreLite" boards from NXP.
    Quad Cortex/A53-based "imx8q-evk" boards from NXP.
  • Printed course material (in English)
  • One Linux PC for two trainees.
  • One target platform for two trainees
  • Any embedded systems engineer or technician with the above prerequisites.
  • Prerequisites are checked before the course starts, against the prerequisites published on this page.
  • Throughout the course, learning is assessed continuously: guided lab work, exercises reviewed with the trainer, end-of-section quizzes and direct observation by the trainer.
  • At the end of the course, each participant receives a training completion certificate.
