RTOS/OMAP-L138: Processor SDK Training/Workshop/Guides

Part Number:OMAP-L138

Tool/software: TI-RTOS

Hi All,

I am fairly new to software development so please bare with me. I am currently developing a DSP board and decided to use OMAP-L138. I am using Processor SDK and CCS v8. Are there any current available workshops to get my feet wet on Processor SDK? The TI-RTOS workshop that I just did was a bit outdated and the labs wouldn't even build on my CCS v8.

I am at the point right now where I wanted to write my own Hello World code and use TMDSLCDK138 EVM board for evaluation purposes. The problem I'm having is that I don't even know how to use the GPIO API's. I ran the LLD examples and it worked (blinked LED) but since I wanted to write my own code just for practice, I don't know how to do this. Right now all I have is this on my main.c :

/*
 *  ======== main.c ========
 */

#include <xdc/std.h>

#include <xdc/runtime/Error.h>
#include <xdc/runtime/System.h>

#include <ti/sysbios/BIOS.h>

#include <ti/sysbios/knl/Task.h>

#include <ti/drv/gpio/GPIO.h>

/*
 *  ======== taskFxn ========
 */
Void taskFxn(UArg a0, UArg a1)
{
    System_printf("enter taskFxn()\n");

    Task_sleep(10);

    System_printf("exit taskFxn()\n");

    System_flush(); /* force SysMin output to console */
}

/*
 *  ======== main ========
 */
Int main()
{ 
    Task_Handle task;
    Error_Block eb;
    
    System_printf("enter main()\n");

    Error_init(&eb);
    task = Task_create(taskFxn, NULL, &eb);
    if (task == NULL) {
        System_printf("Task_create() failed!\n");
        BIOS_exit(0);
    }

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

tl;dr

I need step-by-step documentation from scratch to simple LED blinking application. And documentation on how to use Processor SDK API's.

Thanks!
