FCQ3 P204X QorIQ implementation

This course covers NXP QorIQ P2040 and P2041

  • This course has 6 main objectives:
    • Describing the hardware implementation, particularly the boot sequence and the DDR3 controller
    • Understanding the features of the internal interconnect and related units and mechanisms such as PAMU, CPC and stashing
    • Describing the units which are interconnected to other modules, such as clocking, interrupt controller and DMA controller, because the boot program generally has to modify the setting of these units
    • Explaining the standard bus interface controllers, PCIe, SRIO, USB, SATA and MMC-SD
    • Clarifying the operation of the Datapath Acceleration Architecture that assists the processor core in taking in charge buffer allocation, queue management, frame management and particularly incoming frame classification, pattern searching, and encryption
    • Describing the various debug units and their utilization to fix errors in a multicore / multimaster SoC.

  • Products and services offered by ACSYS:
    • ACSYS is able to assist the customer by providing consultancies
    • Typical expertises are done during board bringup, hardware schematics review, software debugging, performance tuning.
    • Note that ACSYS has delivered several consultancies on NXP Netcomm SoCs to companies developing avionic equipments.
A more detailed course description is available on request at
This document is necessary to tailor the course to specific customer needs and to define the exact schedule.
  • Experience of a 32-bit processor or DSP is mandatory.
  • Note that the e500mc Power core is covered in a separate course reference FCC1 - e500mc implementation course.
  • The e500mc cores implemented in the P2040 do not support L2 caches.
  • 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.
