MQX Lite LED task not work

yogesh8418 — Tue, 04 Jun 2013 08:38:07 GMT

Hi ,

I am using FRDM-KL25Z and I have successfully Written LED blink program using code warrior. I am also able to run all the sample program from freescale start up kit.

Now I am writing A MQX Lite program to blink LED's using MQX tasks.

I made three tasks One for Initialising and 2 other for blinkin the LEDs on the board using task.

The task declaration in task_template_list.c is below

#define TASK_TEMPLATE_LIST_END {0, 0, 0, 0, 0, 0, 0}

/* MQX task template list */

const TASK_TEMPLATE_STRUCT MQX_template_list[] =

{

/* Task: InitTask */

{

/* Task number */ INITTASK_TASK,

/* Entry point */ (TASK_FPTR)InitTask,

/* Stack size */ INITTASK_TASK_STACK_SIZE,

/* Task priority */ 8U,

/* Task name */ "inittask",

/* Task attributes */ (MQX_AUTO_START_TASK),

/* Task parameter */ (uint32_t)(0)

/* Task: LEDTask */

{

/* Task number */ LEDTASK_TASK,

/* Entry point */ (TASK_FPTR)LEDTask,

/* Stack size */ LEDTASK_TASK_STACK_SIZE,

/* Task priority */ 10U,

/* Task name */ "ledtask",

/* Task attributes */ (0),

/* Task parameter */ (uint32_t)(0)

/* Task: GR_LED_ON */

{

/* Task number */ GR_LED_ON_TASK,

/* Entry point */ (TASK_FPTR)GR_LED_ON,

/* Stack size */ GR_LED_ON_TASK_STACK_SIZE,

/* Task priority */ 9U,

/* Task name */ "gr_led_on",

/* Task attributes */ (0),

/* Task parameter */ (uint32_t)(0)

TASK_TEMPLATE_LIST_END

};

Now in the mqx_tasks.c I have written a code like below

But when I debug the program I only blinks the LED of the higher priority and the other task is not working .....

Can anyone suggest me what mistake I am doing .

Thanks

I have also attached my code warrior project..

Hi Martin,

If followed your instructions and Now The program works.

Thank you very much for replying.
