This course covers UHS-II which is the enhanced version of SD

formateur
Objectives
  • This course explains how legacy SD commands are transported over UHS II.
  • The hardware layer is detailed, including the analog part.
  • The link layer operation is explained through sequences clarifying flow control and acknowledgement mechanisms.
  • The course describes the low power modes.
  • The enumeration and configuration for a point-to-point or ring topology is studied.
  • Data protection system is also covered.

  • This training has been delivered several times to companies developing SoCs for wireless / consumer market.
A more detailed course description is available on request at training@ac6-training.com
  • Experience of mass-storage interface, such as SD/MMC or USB mass storage class 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
