Need help about FreeRTOS with TMS570

Other Parts Discussed in Thread: TMS570LS0432, HALCOGEN

 Hello,

I'd like to get started with some simple example of RTOS (no necessary FreeRTOS) for TMS570LS0432 board. But, unfortunately, I wasn't able to find any working example. So maybe someone could point me to some kind of tutorial video or at least article.

Regards,

And thanks in advance.

    Hi

    Download Latest HALCoGen version from below Link and Install.

    http://www.ti.com/tool/halcogen

    Once HALCoGen is installed you can find two FreeRTOS blinky example in the default install folder.

    C:\ti\Hercules\HALCoGen\v03.05.02\examples\TMS570LS31x\example_freeRTOSBlinky.c and example_freeRTOSRestrictedTask.c

    Hi Prathap,

    So I have HalCoGen 3.05.00 installed at the moment.   There is a TMS570LS0432PZ_FREERTOS project template available.

    Is the suggestion to:

       a) create a project using this TMS570LS0432PZ_FREERTOS template

       b) copy the example_freeRTOSBlinky.c file into the new project as a replacement for the sys_main.c file?

    In order to run on the 0432 instead of the 3137?

    Hi Anthony,

    Yes, you got it right.

     Hey everyone,

    Thanks for fast response. But I didn't want to verify the answer before I get the example running.
    So I tried doing everything as description in .c file says, but eventually I got into some kind of error of HalCoGen.

    New project for "TMS570LS0432PZ_FREERTOS".

    When I go to "TMS570..->Interrupts" and enable IRQ "Dispatch Mode". All the rest of properties are untouched, just to show the error that occurs.

    I get these errors in CCS 5.4:

    #10010 errors encountered during linking; "trinti1.out" not built

    <a href="file:/C:/ti54/ccsv5/tools/compiler/dmed/HTML/10234.html">#10234-D</a>  unresolved symbols remain

     unresolved symbol _isrStub, first referenced in ./source/sys_intvecs.obj

     

    And I can't go on with running this example.

     

    Regards,

    Vytautas

    Hi Vytautas,

    Are you using HALCoGen 3.05.02?

    The new project for TMS570LS0432PZ_FREERTOS on 3.05.02 should not have this issue.

    Please seelct the "Vector mode" fro IRQ as in the image

     

    Regards

    Hello,

    I've managed to run "example_freeRTOSBlinky", although description of how to run it, isn't exactly right. As pointed out by Prathap- you don't have to enable dispatch mode and you don't have to change any handler names. In fact the only thing I had to change, was enabling GIO driver and generate code. Another thing I was missing, that althoug you enable GIO drivers, you are controlling NHET channels.

    Thanks for everyone's patience.

    Regards,

    Vytautas

    Hi Prathap,

    I have HalCoGen 3.05.02. When I create new project only TMS570LS1227ZWT_FREERTOS project template available. I'd like uses TMS570LS1227PGE and FREERTOS . How can I do it?

    Regards, And thanks in advance

    Agoda,

    The TMS570LS1227ZWT and PGE are both the same silicon - the package is the only difference.

    With the PGE you will see 2 main differences:

      a) have to run at a slower frequency, see table 3.3 in the datasheet SPNS162A,  "Switching Characteristics over Recommended Operating Conditions..."

      b) there are a lot fewer IO

    Since (b) is something you'd get to later as you start to turn on peripherals in HalCoGen,  you should be able to simply create a *ZWT_FREERTOS project, but then change the clock frequency down to 160MHz -- and you'll be up and running at least.
