hello

every expects

This is Tomiyama from Tokyo.

When I code task in app.cfg file just as bellow:

var task1Params = new Task.Params();
task1Params.instance.name = "taskHeadCyc";
Program.global.taskHeadCyc = Task.create("&taskHeadCyc", task1Params);

Q1.Are there need to write main.c with this code:

    Task_Params_init(&task1Params);
    task1Params.instance->name = "task2";
    task1Params.stackSize = 2048;
    task1Params.arg0 = 2;
    task1Params.priority = 15;
    Error_init(&eb);
    task = Task_create(taskHeadCyc, &task1Params, &eb);
    if (task == NULL) {
        System_printf("Task_create() failed!\n");
        BIOS_exit(0);
    }

Q2.If there are no need to write code with upper code, How can I call the task fuction ?

I need your help.

Thank you very much.

Tomiyama.

Tomiyama,

Please follow this example in the Processor SDK RTOS package for AM335x C:\ti\pdk_am335x_1_0_9\packages\MyExampleProjects\USB_DevMsc_evmAM335x_armExampleProject

It shows you how to setup your tasks for a USB applicaiton.

You will see that main() looks like below in this example

int main(void)
{

    Task_Handle task;
    Error_Block eb;

    Board_initCfg boardCfg;
    boardCfg = BOARD_INIT_MODULE_CLOCK |
        BOARD_INIT_PINMUX_CONFIG |
        BOARD_INIT_UART_STDIO;
    Board_init(boardCfg);

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