FM1 MPC5XX implementation

This course covers MPC55X and MPC56X NXP MCUs

formateur
Objectives
  • This training highlights differences between MPC55X and MPC56X.
  • The hardware implementation is fully described, especially burst transfers.
  • A boot program has been developped.
  • The course focusses on PowerPC EABI, which is fundamental for low level programmers.
  • A generic interrupt handler supporting nesting is introduced.
  • TPU3 functions are studied with the help of a logic analyser.
  • QADC operating modes are described.
  • The course details the internal debug facilities particularly the MPC56X nexus port.
A lot of programming examples have been developed by ACSYS to explain the boot sequence and the operation of complex peripherals, such as QADC and TPU.
•  They have been developed with Diab Data compiler and are executed under Lauterbach debugger.
A more detailed course description is available on request at training@ac6-training.com
  • Experience of a 32-bit processor or DSP is mandatory.
  • The following course 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.
