D1SEmbedded Linux with Ac6 System Workbench
Implementing Linux on Embedded Systems
|
Objectives
|
||||||||||||||||||
- Printed course material (in English)
- One Linux PC for two trainees.
- One target platform for two trainees
| A version of “Ac6 System Workbench for Linux – Basic Edition” is provided free of charge to each trainee | ||
- Good C programming skills
- Knowledge of Linux user programming (see our D0 - Linux user mode programming course)
- Preferably knowledge of Linux kernel and driver programming (see our D3 - Linux Drivers course)
- 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 in two different ways, depending on the course:
- For courses lending themselves to practical exercises, the results of the exercises are checked by the trainer while, if necessary, helping trainees to carry them out by providing additional details.
- Quizzes are offered at the end of sections that do not include practical exercises to verifythat 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.
