Programming Embedded Linux Applications for Linux

Objectives

  • Discover Linux and its development tools
  • Connect an embedded Linux system in a network
  • Review the Linux boot sequence
  • Mount a remote file system
  • Boot a remote Linux kernel
  • Program and Debug Linux applications
    • Network programming
    • Synchronous and asynchronous input-output
    • Multi-thread programming
    • Inter-process communications
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.
  • Engineers that must create embedded Linux applications
  • Basic Linux user knowledge
  • Good C programming skills
  • 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 training.
  • Progress is assessed by the trainer through the practical exercises, and by quizzes for sections without exercises.
  • Each trainee receives a completion certificate.
  • If a prerequisite gap appears, alternative or additional training is offered.
