CCS: CONNECTING USB on F28379D controlCARD

Other Parts Discussed in Thread: TMS320F28379D

Tool/software: Code Composer Studio

I read in the documentation that if the card is connected to the USB cable it will blow the card.  I have not yet connected the card but would like to know if this is still true. I have just receive the board and the serial number is sp8_1803622B. If I understand the documentation correctly this is version 1.3 and does no longer have this problem.

Therefore is it safe to connect it to the PCB USB and get powered from the PC USB +5V

    Erastus,
    What note are you referencing?

    There is an older warning for R1.1 controlCARDS, that sounds similar to what you are stating. You will not have that issue if you have a newer controlCARD revision.

    Hi Cody,


    3.1 Warnings/Notes/Errata
    Notes for all controlCARDs:
    Delfino TMS320F28379D controlCARD R1.3
    User's Guide

    SOmehow it is not possible to get my PC and Code Composer to talk to the card.
    I am not sure if I must do the following:
    4. R83 on the controlCARD is populated to allow a customer to evaluate the controlCARD without a
    baseboard if desired. Because R83 is populated, the controlCARD will put more capacitance on the
    USB 5V supply than the USB specification allows. R83 should be removed in order to meet the
    specification.

    I only connected the board after I received you response
    Lights came on
    Ld1 Green
    LD2 Red
    LD3 Red
    Came on but htat is it.
    It does not get picked up by the USB.
    I can not see tht I must load drivers.

    Erastus,
    in the future please start a new thread for unrelated questions, it will keep the forum more organized and ensure you recieve the best support possible.

    The F28379D has 1MB of flash and about 200KB of RAM, which is a good size for a microcontroller of this type. My first thought is you are not linking your code to the full available memory. The following wiki article explains linking pretty well.
