Concerto F28M35H52C1

Other Parts Discussed in Thread: CONTROLSUITE

Hi,

constructing our first application test board we encounter some problems concerning demo programs provided by TI.

We are running code composer studio 5.1.0.09000  using a Concerto F28M35H52C1 and a XDS100v2 debugger from Spectrum Digital for programing.

The demo project, we've tried to run, is the control suite example project which toggles port a.

The result we get is that we can see the internal registers for port a toggling, but the outputs stay low.

We also modified the ports to toggle but again there was no action at the pins.

Is this a common issue or did we something wrong concerning adjustment of periphals (we did not modify the code of the example project) ...

Any help is wellcome!

Thank you

Pirmin

    Hi Pirmin,

    Could you give me the exact name of the example project you are trying to run?

    I suspect you might be trying to toggle pins from the C28x side of Concerto and you don't have the GPIOs assigned to the C28x, but I can't be certain without more information.

    The program ist called blinky from the control suite example project folder for host example projects.

    I've variated the ports, too.

    Could you also tell me what version of the device support library you are using?

    Dear Trey,

    We did not find a specific device support library.c-file but maybe the release-date and version of
    the F28M35x Driver Library and the path of the project provides you with enough information:

    Path of the project:
    C:\TI\controlSUITE\device_support\f28m35x\v100\F28M35x_examples_Master\blinky\m3

    //###########################################################################
    // FILE:   blinky.c
    // TITLE:  blinky example.
    //###########################################################################
    // $TI Release: F28M35x Driver Library v100 $
    // $Release Date: October 12, 2011 $
    //###########################################################################

    If this is not what you intended, please provide the path of the folder, where the library usually is.

    Thank you

    Pirmin,

    That's exactly what I was looking for. 

    We test all of the examples before we release them, but I just double checked and the v100 blinky example does in fact work.  Are you 100% positive you didn't modify anything in the example sources?  If you can see the data register switch toggle but can't see it on the pin maybe you don't have the digital enable (register DEN) bit set or you accidentally setup the pin to use one of its alternate peripheral functions(register AFSEL)?  Also keep in mind that the GPIO registers are MWRALLOW protected, so unless protection is disabled CPU writes to these registers will not work.

    We just released a new version of the device support library for Concerto.  Try updating your controlSUITE installation and look for the v110 folder.  There are a number of bugfixes and enhancements to this release.  Try the blinky example from this new release and let me know if you are still having trouble.
