FA1 i.MX27 implementation + LTIB

This course describes the i.MX27 multimedia processor and Linux Target Image Builder tool

formateur
Objectives
  • The course details the hardware implementation of the i.MX27 microcontroller.
  • The boot sequence and the clocking are explained.
  • The course explains all parameters that affect the performance of the system in order to easily perform the final tuning.
  • A description of all internal peripherals is provided.
  • An overview of the ARM926EJ-S core helps to understand issues caused by cache and MMU.
  • The course ends with practical labs explaining how to generate a Linux image as well as a Root File System, by using a tool called LTIB [Linux Target Image Builder].

  • This course has been delivered to several companies developing multimedia equipments.
A lot of programming examples have been developed by ACSYS to explain the boot sequence and the operation of complex peripherals.
•  They have been developed with GNU compiler and are executed under Lauterbach debugger.
•  Furthermore, a host desktop running Fedora Linux is used to generate Linux image and Root File System during labs on LTIB.
A more detailed course description is available on request at formation@ac6-formation.com
  • This course provides an overview of the ARM926 core. Our course reference R1 - ARM7/9 implementation course details the operation of this core.
  • The following courses could be of interest:
  • Theoretical course
    • PDF course material (in English) supplemented by a printed version for face-to-face courses.
    • Online courses are dispensed using the Teams video-conferencing system.
    • The trainer answers trainees' questions during the training and provide technical and pedagogical assistance.
  • At the start of each session the trainer will interact with the trainees to ensure the course fits their expectations and correct if needed
  • Any embedded systems engineer or technician with the above prerequisites.
  • The prerequisites indicated above are assessed before the training by the technical supervision of the traineein his company, or by the trainee himself in the exceptional case of an individual trainee.
  • Trainee progress is assessed by quizzes offered at the end of various sections to verify that the trainees have assimilated the points presented
  • At the end of the training, each trainee receives a certificate attesting that they have successfully completed the course.
    • In the event of a problem, discovered during the course, due to a lack of prerequisites by the trainee a different or additional training is offered to them, generally to reinforce their prerequisites,in agreement with their company manager if applicable.
