This course covers UFS 2.0 , which is the enhanced version of MMC standard
|
OBJECTIVES
|
|||
- Experience of mass-storage interface, such as SD/MMC, USB mass storage class or SATA is recommended.
- 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
