FA2 | i.MX31 implementation + LTIB |
This course describes the i.MX31 multimedia processor and Linux Target Image Builder tool
|
Objectives
|
- Knowledge of ARM1136JF-S is recommended, see our course reference R2.
- Knowledge of USB is recommended, see our course reference IP2 - USB 2.0 course
- ACSYS also offer a large set of courses on Linux.
- 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.
