CCS/TMS320F28377S: Demo SYS/BIOS LED Blinky Project

hello Todd, 6_76_02_02 is installed, which I found SYS/BIOS and Non-BIOS projects.  Within the  BIOS projects, I did not find a Blinky.

Starting with a non-BIOS Blinky  project, I added RTSC configuration file. Which resulted in "linker" and "invalid re-declaration" "compiler errors, of which some I resolved.

My question is, Staring with any Non RTOS project is it possible to add SYS/BIOS, if so is there step-step process.

When using the BIOS, which includes and header files are not required, to blink a LED.

thanks

The SYS/BIOS product does not have any "peripheral" examples like blinky or serial. The only peripherals the kernel interfaces with are the timers and vector table. 

I'd recommend starting with a SYS/BIOS example and add functionality onto it instead of taking a non-SYS/BIOS example and trying to add the kernel into it.

using SYSBIOS "Task" as the base project  and adding :

//////////////////////////////////////////////////////////////////

     InitSysCtrl();
     InitGpio();
     GPIO_SetupPinMux(BLINKY_LED_GPIO, GPIO_MUX_CPU1, 0);
     GPIO_ SetupPinOptions(BLINKY_LED_GPIO, GPIO_OUTPUT, GPIO_PUSHPULL);
     DINT;
     InitPieCtrl();
     IER = 0x0000;
     IFR = 0x0000;
     InitPieVectTable();
      EINT;  // Enable Global interrupt INTM
      ERTM;  // Enable Global realtime interrupt DBGM
//////////////////////////////////////////////////////////////////
      Task_Params taskParams;
    
     /* Create a Semaphore object to be use as a resource lock */
     sem = Semaphore_create(1, NULL, NULL);


    /* Create two tasks that share a resource*/
    Task_Params_init(&taskParams);
    taskParams.priority = 1;
    tsk1 = Task_create (task1, &taskParams, NULL);
    
    Task_Params_init(&taskParams);
    taskParams.priority = 2;
    tsk2 = Task_create (task2, &taskParams, NULL);

    BIOS_start();    /* does not return */
    return(0);

this resulted in new code indiscreetly mixed with sysbios code (I'm guessing) and the code hanging in timer2 interrupt  when running on the launch pad.  .When the blinky code is removed, the base project run as expected.

Which sections of the blinky code are required for the sysbios project.

thank

You should not be managing the vector table directly. The kernel is manages this instead. For the timer, you need to use the ti.sysbios.hal.Timer module.

 Can you confirm that the following items are not required:

InitSysCtrl();

     DINT;
     InitPieCtrl();
     IER = 0x0000;
     IFR = 0x0000;
     InitPieVectTable();
      EINT;  // Enable Global interrupt INTM
      ERTM;  // Enable Global realtime interrupt DBGM

thanks

hello Tom

I tumbled across this thread, can you provide a link to the lessens

e2e.ti.com/.../666344

The older workshop has been replaced with this: https://training.ti.com/getting-started-ti-rtos-training-series

The new  workshops lack substance which I require, is it possible to obtain a copy of the original workshop.

thanks

We are working on it, but don't have a timeframe.
