Other Parts Discussed in Thread: TMS320F28388D, C2000WARE

Hello,

I have some questions about using TMS320F28388D chip. 

1. In the example project,  there are 4 types sample. Would you tell me about the difference of these project?

   I understand as follows, 

   1) c28x (first project) : this makes the single CPU Project

   2) c28x_dual : this makes the the same project Both CPU 

   3) the others : I don't kwow about "CM" project 

2. About using dual project, I want to know about How to use dual CPU

  1)  Is each CPU acts independently?

  2)  What parameter I change for debug each CPU? 

Regards,

Minwoo

    Minwoo, 

    F2838x has three cores - two C28x cores and one Cortex M4(CM) cores. 

    Answer to first part of your question:

    1. c28x  : This folder contains examples which run exclusively on the C28x CPU1 core .
    2. c28x_dual : This folder contains examples which require both C28x CPU Cores to run.
    3. cm : This folder contains examples which run exclusively on the CM core 
    4. c28x_cm : This folder contains examples which require both cores - CM and C28x to run .

    Answer to second part of your question:

    These examples (c28x_dual) show how to make use of F2838x device functions which span both the cores - CPU1 and CPU2.

    All of these examples contain two example projects: one for CPU1 and one for CPU2. 

    To run one of these examples after compiling it, load the appropriate programs on each of the two cores. Then, for more example specific instructions please refer to the documentation regarding the example you wish to run in the fimware example user guide or in the comments of the example sources.

    You can refer the firmware example user guide (F2838x_FRM_EX_UG.pdf) provided in C2000Ware to know details about each example project. It is locted at <C2000WareInstallDir>\device_support\f2838x\docs

    Best Regards
